- Every payment-required error now ends with a "Next step" line: the
  platform hint when one is sent, else the topup command and the billing
  URL for the configured platform. JSON output gets the same text as
  next_step. The platform hint is no longer repeated inside the error.
- An archive file passed to --source is rejected with guidance to pass
  the directory instead, which packs and excludes deps/build output.
- An oversize archive names its largest files and points to --exclude
  and --dry-run --show-files.
- uploads request help points to scans start --source for local code.

-  - API docs: https://docs.app.strix.ai (OpenAPI: https://docs.app.strix.ai/openapi.json).
+  - Account setup runs from the CLI too: `strix cloud workspaces list|create|use` (`workspace` is an alias and `use` accepts a displayed number, name, or ID), `strix cloud session scopes|scopes set`, `strix cloud org members invite`, `strix cloud billing subscribe --plan strix_cloud`, `strix cloud billing portal`, `strix cloud integrations install github`, and `strix cloud domains verify <id>`. Workspace switching preserves the server-side profile and can never widen past the login ceiling; ordinary switches do not reprompt. The last four end at a person: the command prints a link or a DNS record for the user to open or add, and it never completes the payment, installation, or DNS change for them.
+  - Every REST operation has a `strix cloud <resource> <verb>` command. Run `strix cloud` to list them. Output is JSON when stdout is not a terminal (or with `--json`), and there are no prompts without a TTY. Binary downloads are the exception: redirect raw bytes intentionally, or combine `--output FILE --json` for structured download metadata. Exit codes: `0` success, `1` error, `2` usage, `4` auth or plan limit, `5` payment required. `--token` or `STRIX_API_TOKEN` is a stateless override and never replaces stored auth; set `--workspace-id`/`STRIX_WORKSPACE_ID` for an override CLI session. `--data` adds extra request fields as JSON, and accepts `@file` or `-` for standard input.
+  - Local source uploads require `uploads:write`. For an agent/CI handoff, review `scans start --source . --dry-run --show-files --json`, capture `source.archive_sha256`, then rerun with the same `--source`, `--exclude`, and `--include-*` selection flags plus `--approve-sha256 HASH`. A changed snapshot is rejected. `--yes` approves only the snapshot built in that invocation, so reserve it for a deliberate human or one-shot approval rather than a digest-bound two-step handoff.
+  - Git ignores, hidden files, `.git`, symlinks, dependency/build output, secret-like filenames, and nested archives are excluded by default; `.strixignore` and `--exclude` narrow the manifest further (a trailing `/` excludes a directory subtree). Limits: 20,000 files, 25 MiB/file, 250 MiB expanded, 50 MiB compressed. Source-only infers `code_review`; source plus a domain infers `live_test`.
+  - The temporary local archive is always removed. A staged upload is deleted after a definitive rejection, but retained when a network error, `5xx`, malformed success response, or interruption leaves the scan launch ambiguous. JSON reports its `upload_id` with `launch_outcome_unknown: true`, or with `cleanup_unknown: true` when automatic deletion cannot be confirmed. Check `scans list` before retrying; if no scan is linked, run `uploads delete UPLOAD_ID`.
+  - Non-Enterprise scans consume the scope estimate (a default-tier source-only review currently starts at 60 credits); Enterprise scans are plan-included. A rejected launch does not consume credits.
+  - Human output is compact and numbered; non-TTY output and `--json` retain full records. Enable tab completion with `source <(strix completions zsh)` (or `bash`), or `strix completions fish | source`.
+  - The REST API works directly too: https://docs.app.strix.ai (OpenAPI: https://docs.app.strix.ai/openapi.json).

+```
+
+A browser sign-in creates one reusable credential for each CLI installation. A second sign-in on the same installation replaces the secret instead of adding another key. `strix cloud logout` revokes the server session before it deletes the local token. Use `--local-only` when you cannot reach the server.
+
+## Scopes
+
+The default **Recommended** preset covers normal scan work, local source uploads, workspace switching, and user-approved credit top-ups. It excludes credential creation, so request `tokens:write` when you need it.
+
+```bash
+strix cloud login --scopes scans:read scans:write uploads:write billing:read
+strix cloud login --scope-profile minimal   # also accepts recommended or full
+strix cloud session scopes                  # granted scopes and the login ceiling
+strix cloud session scopes set minimal      # narrow without another browser sign-in
+```
+
+A workspace switch keeps the credential and its expiry, preserves the server-side scope preference, and caps access by the target role. A switch can never exceed the login consent ceiling. Each process pins the workspace it started with, so a concurrent switch fails safely instead of sending a stale command to another organization.
+
+## Commands
+
+Every operation of the [REST API](https://docs.app.strix.ai) has a matching command in the form `strix cloud <resource> <verb>`.
+
+```bash
+strix cloud                                   # list all resources
+strix cloud scans                             # run the safe default (scans list)
+strix cloud scans help                        # list the verbs of a resource
+strix cloud domains add --domain example.com --asset-type web_app
+strix cloud scans start --engagement-type live_test --domain-ids <uuid> --wait
+strix cloud vulns list --severity critical
+strix cloud credits                           # credit balance
+```
+
+Write commands take request fields as flags. Every write command also accepts one JSON object with `--data`:
+
+```bash
+strix cloud scans start --data '{"engagement_type":"code_review"}'   # literal JSON
+strix cloud scans start --data @request.json                         # read a file
+cat request.json | strix cloud scans start --data -                  # read standard input
+```
+
+`--token` and `STRIX_API_TOKEN` are stateless overrides for a single command, and they never replace the stored sign-in. Pair a CLI-session override with `--workspace-id` or `STRIX_WORKSPACE_ID`.
+
+## Workspaces And Account Setup
+
+```bash
+strix cloud workspaces list                       # numbered list; workspace is also accepted
+strix cloud workspaces create --name "My Team"    # needs admin and organizations:write
+strix cloud workspaces use 2                      # switch by list number, exact name, or ID
+strix cloud billing topup --credits 20 --yes      # approve an agent payment after HTTP 402
+strix cloud billing subscribe --plan strix_cloud  # opens the hosted checkout page
+strix cloud billing portal                        # opens the billing portal
+strix cloud integrations install github           # opens the app installation page
+strix cloud domains verify <domain-id>            # prints the DNS record to add
+```
+
+The last four commands end at a person. Strix creates the link, opens the browser for an interactive terminal, and always prints the URL. The user enters the card, approves the installation, or adds the DNS record. Pass `--no-browser` to print the URL only.
+
+## Output And Exit Codes
+
+The commands work for people and for agents. Terminal output favors names, branches, lifecycle states, and numbered selectors. Redirected output, and `--json`, preserve the complete machine-readable record.
+
+- Human lists keep the selectors that follow-up commands need, and they omit internal organization and user IDs. A selector that is too long for the compact table is repeated losslessly in a copyable block.
+- Paginated lists print the next `--page` or `--offset`. Detail views keep useful prose within a safe terminal bound, so use `--json` for the complete record.
+- Token lists separate API keys from named CLI device sessions.
+- Binary downloads are the exception to JSON output. Redirect the raw bytes on purpose, or use `--output FILE --json` to write the file and receive structured download metadata.
+- There are no prompts when stdin is not a terminal.
+
+Exit codes: `0` success, `1` error, `2` invalid usage, `4` authentication or plan limit, `5` payment required.
+
+## Credits And Plan Limits
+
+Non-Enterprise scans consume the deterministic estimate shown for their scope. A source-only code review at the default `ultra` tier currently starts at 60 credits. Enterprise scans are plan-included and do not consume the credit wallet.
+
+Report downloads need Enterprise, schedules need Pro, and billing writes need an admin token. A plan block exits `4`. An insufficient credit wallet exits `5` without the creation of a scan and without a charge.
+
+## Local Source Scans
+
+See [Scan Local Source](/cloud/overview#scan-local-source) for the upload approval flow, the exclusion rules, and the size limits.
+
+## Tab Completion
+
+Enable native tab completion once for each shell session:

Hidden files, `.git`, symlinks, dependencies and build output, secret-like filenames, and nested archives are excluded by default. Use `.strixignore` or repeat `--exclude GLOB` for project-specific exclusions. `--include-hidden`, `--include-sensitive`, and `--include-archives` are explicit opt-ins.
+
+The CLI limits individual files, total expanded bytes, archive bytes, and file count. For an agent or CI handoff, repeat the same `--source`, `--exclude`, and `--include-*` flags with `--approve-sha256`; Strix refuses the upload if the rebuilt archive differs from the reviewed digest. `--yes` is a one-invocation approval for the snapshot built at that moment, not a digest-bound two-step approval.
+
+The temporary local archive is always removed. After a definitive launch rejection, Strix also deletes the staged remote upload. If a network error, server error, or interruption makes the launch outcome ambiguous, it retains the upload and reports its ID; check `strix cloud scans list` before retrying, then delete an unlinked upload with `strix cloud uploads delete UPLOAD_ID`.

The `managed-pentesting-with-strix` skill has the full flow.
 
 ## Agent-Friendly Interfaces
 
 Everything an agent needs is machine-readable:
 
 - **Headless CLI** — `strix -n` runs without the TUI and exits with `0` (clean), `1` (error), or `2` (vulnerabilities found).
+- **Cloud CLI** — `strix cloud` prints JSON when stdout is not a terminal (or with `--json`), never prompts without a TTY, and exits with `0` (success), `1` (error), `2` (usage), `4` (authentication required), or `5` (payment required). Credit top-ups pay the Stripe machine-payment challenge with an agent wallet (`strix cloud billing topup --credits N --yes`). Account setup also runs from the CLI: `strix cloud workspaces list|create|use`, `strix cloud org members invite`, `strix cloud billing subscribe`, `strix cloud billing portal`, and `strix cloud integrations install github`. The last three print a hosted link the user opens to finish the payment or approve the installation.
 - **REST API** — the managed platform exposes a documented [OpenAPI](https://docs.app.strix.ai/openapi.json) at `https://app.strix.ai/api/v1` (scans, vulnerabilities, assets, PR reviews, schedules, webhooks) with bearer tokens and scopes.
 - **Structured results** — every run writes `vulnerabilities.json`, `vulnerabilities.csv`, `findings.sarif` (SARIF 2.1.0), and per-finding Markdown under `strix_runs/<run-name>/`; the cloud exposes the same as JSON plus SARIF export.
 - **Budget controls** — `--max-budget` and `--max-turns` give agents hard cost/time caps.

+- **Agent graph** — a live map of the multi-agent team, and what each agent is doing.
+- **Steering** — send instructions to a live scan to redirect the agents during the run. Steering works only in the dashboard the running scan opens. A standalone `strix view` has no live scan to steer.
+- **History** — browse past runs on this machine and move between them. Verify your email address in the dashboard to unlock the other runs.
+- **Reports** — generate a shareable report and send it by email. Verify your email address first.
+
+## Sharing The Link
+
+<Warning>
+  The token in the printed URL grants access to the run data, and to the steering of a live scan. Share it only with trusted users.

+
+To reach the viewer from another machine, start it with `--host 0.0.0.0` and replace `0.0.0.0` in the printed URL with a reachable IP address or hostname. Restrict the port with your firewall. A request without the token-derived session cannot read run data.

+# Strix Cloud (managed, no local infra)
 
 Use this when you want Strix's autonomous pentesting **without running Docker or an LLM yourself** — the scan runs on Strix's infrastructure and results are tracked in a team dashboard. This is the right choice in sandboxed/hosted agent and CI environments, for teams, and for scheduled/continuous testing (downloadable PDF/DOCX reports are an Enterprise-plan feature). For fully local, free, air-gapped, or BYO-LLM runs, use the open-source CLI in the **penetration-testing-with-strix** skill instead — both share the same engine and SARIF output, so you can mix them.
 
-Full reference: **[docs.app.strix.ai](https://docs.app.strix.ai)** · OpenAPI: `https://docs.app.strix.ai/openapi.json`
+There are two equivalent interfaces. Prefer the CLI:
 
-## Setup
+- **`strix cloud` CLI** — every REST operation has a command in the form `strix cloud <resource> <verb>`. Install with `curl -sSL https://strix.ai/install | bash`. Run `strix cloud` to list all resources and `strix cloud <resource> help` (or `-h`) to list a resource's verbs; a bare resource with a safe read operation runs its documented default.
+- **REST API** — base URL `https://app.strix.ai/api/v1`, `Authorization: Bearer <token>` on every request. Full reference: **[docs.app.strix.ai](https://docs.app.strix.ai)** · agent index: `https://docs.app.strix.ai/llms.txt` · OpenAPI: `https://docs.app.strix.ai/openapi.json`.
 
-- **Base URL:** `https://app.strix.ai/api/v1`
-- **Auth:** every request sends `Authorization: Bearer <token>`. Tokens are **org-scoped**.
-- **Get a token:** the user creates one in the dashboard at **Settings → API Access** (app.strix.ai). Ask them for it; never hardcode, log, or commit it. Store it in an env var or the CI secret store.
+The CLI is equally usable by agents and people. Output is complete JSON when stdout is not a terminal, or when you pass `--json`; terminal tables favor names, branches, lifecycle states, and numbered selectors. Human lists retain the selectors needed by follow-up commands but omit internal organization/user IDs; a selector too long for the compact table is repeated losslessly in a copyable block. Paginated lists print the next `--page` or `--offset`, and detail views preserve useful prose within a safe terminal bound; use `--json` for the complete record. Token lists label credentials as active, expired, or revoked. Binary downloads are the exception: redirect raw bytes intentionally, or use `--output FILE --json` to write the file and receive structured metadata. There are no interactive prompts when stdin is not a terminal. Exit codes: `0` success, `1` request/runtime error, `2` invalid usage, `4` authentication or plan limit, `5` payment required.
+
+Every resource group with a safe read operation has a useful default action, and `-h` or `help` always shows its verbs. Native tab completion includes resources, verbs, flags, workspace commands, and local paths:
+
+```bash
+source <(strix completions zsh)       # current zsh session
+source <(strix completions bash)      # current bash session
+strix completions fish | source       # current fish session
+```
+
+Write commands take request fields as flags. Every write command also accepts one JSON object with `--data`, which is the way to send fields that have no flag:
+
+```bash
+strix cloud scans start --data '{"engagement_type":"code_review"}'   # literal JSON
+strix cloud scans start --data @request.json                         # read a file
+cat request.json | strix cloud scans start --data -                  # read standard input
+```
+
+The platform enforces plan and role limits, and the CLI passes the platform message through. Report downloads need the Enterprise plan. Schedules need the Pro plan. Billing writes need an admin token. A blocked command exits with code `4`.
+
+## Setup: sign in
+
+Run the device sign-in. It creates the user's account and workspace on first use and stores a personal API token in `~/.strix/platform-auth.json`:
+
+```bash
+strix cloud login
+# Non-interactive least-privilege example:
+strix cloud login --scopes scans:read scans:write uploads:write billing:read vulnerabilities:read assets:read assets:write
+# Or use a stable named profile:
+strix cloud login --scope-profile recommended
+```
+
+The user approves the sign-in in the browser. With `--scopes` (and optionally `--workspace <name-or-id>`) there are no terminal prompts, so the command works from a non-interactive agent shell. In an interactive terminal without flags, the CLI offers a workspace picker and scope presets (Recommended, Full access, Minimal, Custom). Recommended covers ordinary scans, source uploads, workspace switching, and user-approved credit top-ups; it excludes `tokens:write`, which must be requested explicitly when credential management is required. Use explicit scopes for a narrower automation token.
+
+- `strix cloud whoami` is the fast local status. `strix cloud session --json` verifies the remote device session; `strix cloud session scopes` shows both effective access and the immutable login ceiling.
+- `strix cloud logout` revokes the remote session before removing the local token. On a network or server failure it keeps the token so the user can retry; `--local-only` deliberately skips revocation.
+- Every other `strix cloud` command uses the stored token automatically. `--token <token>` or `STRIX_API_TOKEN` is a stateless per-command override and never overwrites the stored account. For an override that is itself a CLI session, also pass `--workspace-id` or set `STRIX_WORKSPACE_ID`.
+- Never hardcode, log, or commit the token. Store it in an env var or the CI secret store.

+
+## 0. Credits & top-ups
+
+Non-Enterprise scans consume org credits. Enterprise engagements are plan-included and do not debit the wallet. Check the balance before a scan (`billing:read`):
+
+```bash
+strix cloud credits
+```
+
+When the balance is too low, buy credits with `strix cloud billing topup` (`billing:write`, admin token). The server answers the first request with **HTTP 402 and a machine-payment challenge** (Stripe Machine Payments Protocol). The CLI pays the challenge with the Stripe Link wallet client when Node.js is available — the user approves the spend in the [Link app](https://link.com/agents). The response returns the receipt (`credits_granted`, `duplicate`, `reference`) and the new balance.
+
+A default-tier source-only code review currently starts at 60 credits. Source uploads are not free: they launch an ordinary `code_review` and use the same deterministic scope estimator. The service checks the full balance before launch, reserves credits atomically only after validation succeeds, and does not create or charge a rejected scan. Retests and Enterprise scans are exempt.
+
+```bash
+strix cloud billing topup --credits 20 --yes   # explicit approval; skips the TTY prompt
+strix cloud billing topup --credits 20 --no-pay   # print the 402 challenge without paying
+```
+
+The default payment path is the Stripe Link wallet. When no wallet is connected, an interactive `strix cloud billing topup` starts the Link sign-in for the user and prints the verification link. The user approves the connection one time in the Link app, and then approves each payment there. No keys or variables are necessary. In a non-interactive process, the command stops and tells the user to connect the wallet at [link.com/agents](https://link.com/agents) or to use the hosted checkout link.
+
+In a non-interactive agent or CI process, payment never proceeds unless the command includes `--yes`. Show the challenge or estimated spend to the user and obtain approval before adding it. `--no-pay` always stops after printing the challenge.
+
+If the user does not want a wallet, create a hosted checkout link with `strix cloud billing subscribe --plan strix_top_up` and give the link to the user. The user pays in the browser.
+
+Automatic top-ups (admin): `strix cloud billing auto-topup` shows the setting. Enable it with:
+
+```bash
+strix cloud billing auto-topup update --enabled --topup-credits 20 --monthly-cap-credits 200
+```
+
+An omitted `--monthly-cap-credits` keeps the stored cap. Pass `--no-monthly-cap` to remove the cap.
+
+### Workspaces and account setup
+
+Manage workspaces with a personal token from `strix cloud login`:
+
+```bash
+strix cloud workspaces list                    # numbered name/role/current list
+strix cloud workspaces create --name "My Team"  # admin + organizations:write
+strix cloud workspaces use 2                   # displayed number, exact name, or ID
+strix cloud workspace use "My Team"            # singular `workspace` alias also works
+strix cloud session scopes                     # effective scopes + consent ceiling
+strix cloud session scopes set minimal         # narrow the session
+strix cloud org members invite --email dev@example.com --role analyst
+```
+
+`workspaces use` retargets the current personal token to a workspace the user already belongs to and stores the updated workspace metadata; the bearer secret and expiry stay unchanged. It does not reprompt during ordinary switches: the server preserves the chosen profile, enforces the immutable login ceiling, and caps effective scopes by the target role. Use `--scope-profile` or `--scopes` to narrow within that ceiling; broader consent requires `strix cloud login` again. The CLI pins each process to the workspace it started in, so concurrent shells fail with a recoverable conflict instead of silently crossing organizations.
+
+### Handoffs a person must finish
+
+Four steps end at the user. The command creates the link or the record and prints it. Strix opens the browser only in an interactive terminal. Pass `--no-browser` to print the URL only.
+
+```bash
+strix cloud billing subscribe --plan strix_cloud # hosted checkout page for the Cloud plan
+strix cloud billing portal                       # billing portal for the card and the plan
+strix cloud integrations install github          # GitHub App or Slack installation page
+strix cloud domains verify <domain-id>           # DNS record to add, then run it again
+```
+
+Give the printed URL or DNS record to the user and wait. Do not claim that the payment, the installation, or the DNS change is complete. Confirm the result afterwards with `strix cloud credits`, `strix cloud integrations list`, or `strix cloud domains list`. All four commands need an admin token, except `domains verify`, which needs `assets:write`.
+
+### Organization knowledge
+
+Agents can manage the organization knowledge base without the dashboard (`knowledge:read` / `knowledge:write`):
+
+```bash
+strix cloud knowledge list --search authentication
+strix cloud knowledge add --title "Authentication" --content "Staging uses SSO."
+strix cloud knowledge update <document-id> --content "Staging uses SSO and TOTP."
+strix cloud knowledge delete <document-id>
+strix cloud knowledge policies add --key staging-only --content "Never test production."
+strix cloud knowledge policies delete staging-only
+strix cloud knowledge repos entries usestrix/strix
+```
+
+Knowledge policy writes require an admin token. Repository names are passed as normal `owner/name` values; the CLI handles URL encoding. The `costs` and `llm-settings` commands target on-prem installations and return `404` on app.strix.ai.

-## 3. Poll to completion
+### Scan a local workspace in the cloud
 
-`GET /scans/{scanId}` (`scans:read`). Status flow: `pending → running → completed` (or `failed` / `cancelled`). Poll on an interval — scans take minutes to hours. Do not block.
+For an agent or CI workflow, bind approval to the exact source snapshot that was reviewed. Run
+the dry run with the intended source-selection flags, review the manifest and selected paths,
+and capture `source.archive_sha256`. Then repeat the same `--source`, every `--exclude`, and
+any `--include-hidden`, `--include-sensitive`, or `--include-archives` flags with
+`--approve-sha256`:
 
 ```bash
-while :; do
-  s=$(curl -sS "$BASE/scans/$scan_id" "${auth[@]}" | jq -r .status)
-  echo "status=$s"; [[ "$s" =~ ^(completed|failed|cancelled)$ ]] && break
-  sleep 60
-done
+strix cloud scans start --source . --exclude 'private/' --dry-run --show-files --json
+# After reviewing the output, capture its source.archive_sha256 value:
+SOURCE_SHA256="<reviewed source.archive_sha256>"
+# Repeat every source-selection flag unchanged; a source-only scan infers code_review.
+strix cloud scans start --source . --exclude 'private/' \
+  --approve-sha256 "$SOURCE_SHA256" --wait
 ```
 
+The CLI rebuilds the archive and refuses the upload if its SHA-256 no longer matches. `--yes`
+has deliberately narrower semantics: it approves only the snapshot built during that one
+invocation. Use it for a deliberate human or one-shot approval, not as the second half of a
+digest-bound agent/CI review. Without a TTY, a source upload requires either matching
+`--approve-sha256` approval or `--yes`; an interactive terminal can instead show the summary,
+the selected filenames when `--show-files` is set, and a `[y/N]` confirmation for its current
+snapshot.
+
+The default selection is privacy-conscious: in a Git worktree it includes tracked files plus untracked files that are not ignored; it honors `.gitignore`, excludes every hidden path component, always excludes `.git`, symlinks, dependencies/build output, secret-like filenames, and nested archives. Add project exclusions to `.strixignore` (one exclude glob per line) or repeat `--exclude GLOB`; a trailing slash such as `private/` excludes that directory subtree.
+
+The client refuses more than 20,000 files, a file over 25 MiB, more than 250 MiB expanded, or a ZIP over 50 MiB. The service then stream-inflates the ZIP and independently rejects malformed or unsupported entries, unsafe paths, too many entries, oversized entries, excessive expanded data, and oversized compressed input, so an untrusted client cannot bypass the ZIP-bomb controls by forging metadata.
+
+Only use `--include-hidden`, `--include-sensitive`, or `--include-archives` after the dry-run manifest shows that the scan needs them. Hidden and sensitive files are separate opt-ins: for example, including `.env` requires both `--include-hidden` and `--include-sensitive`.
+
+The CLI removes its private temporary local archive after every invocation. Once a remote
+upload is staged, a definitive scan rejection causes the CLI to delete it. A network failure,
+`5xx` response, malformed success response, or interruption after scan launch begins is
+ambiguous—the platform may have accepted the scan—so the CLI retains the upload and returns
+its `upload_id` with `launch_outcome_unknown: true`. If an automatic deletion attempt cannot
+be confirmed, it instead returns the retained `upload_id` with `cleanup_unknown: true`.
+Before retrying, run `strix cloud scans list` to avoid a duplicate scan or charge. If no scan
+is linked to the retained upload, remove it with `strix cloud uploads delete UPLOAD_ID`;
+linked uploads cannot be deleted.
+
+With no explicit type, source alone infers `code_review`. Any domain target wins and infers `live_test`, so source plus a deployed domain is the normal white-box live-test workflow. Pass `--engagement-type` when you need to override the inference.
+
+## 3. Wait for completion

+Pass `--wait` to `scans start` to poll until the scan reaches a final state, or poll yourself with `strix cloud scans get <scan-id>` (`scans:read`).

 ## 4. Read findings
 
 The scan-detail response includes `executive_summary`, `methodology`, `recommendations`, a `findings` severity roll-up, and a `vulnerabilities[]` array. Each vulnerability carries `title, severity, status, cvss, cwe, endpoint, method, impact, technical_analysis, poc_description, poc_script_code`, and (for code findings) `code_file`/`code_diff`/`code_before`/`code_after`.
 
 ```bash
-curl -sS "$BASE/scans/$scan_id" "${auth[@]}" \
+strix cloud scans get <scan-id> --json \
   | jq '["critical","high","medium","low","info"] as $order
        | .vulnerabilities
        | sort_by(.severity as $s | $order | index($s))
        | .[] | {title, severity, endpoint, cwe}'
 ```
 
-Cloud severities are `critical | high | medium | low` and statuses are `open | in_progress | fixed | ignored`. Sort by an explicit severity order rather than `sort_by(.severity)`, which sorts alphabetically (critical, high, low, medium).

 ## 7. Continuous testing (schedules & webhooks)
 
-- **Schedules** (`schedules:write`, Pro plan): create recurring scans and trigger them on demand — the managed equivalent of a cron-driven CLI loop.
-- **Webhooks** (`webhooks:write`): subscribe to pentest/vulnerability lifecycle events such as `scan.completed` and `vulnerability.created` to push results into Slack, ticketing, or your own pipeline instead of polling.
+- **Schedules** (`schedules:write`, Pro plan): `strix cloud schedules create` makes recurring scans, and `strix cloud schedules trigger <id>` runs one on demand — the managed equivalent of a cron-driven CLI loop.
+- **Webhooks** (`webhooks:write`): `strix cloud webhooks create` subscribes to pentest/vulnerability lifecycle events such as `scan.completed` and `vulnerability.created` to push results into Slack, ticketing, or your own pipeline instead of polling.
 
 See the schedules and webhooks sections at [docs.app.strix.ai](https://docs.app.strix.ai) for payloads.
 
+Network connectors are Enterprise-only. `strix cloud connectors create` may return a one-time enrollment command containing credentials; do not paste it into logs, and request it with `--include-command` only when the user is ready to install it. Browser checkout, source-control installation, DNS verification, connector installation, chat sharing, and publishing SARIF to an external provider are user handoffs or explicit external mutations—prepare the command/link, then obtain the appropriate approval before completing them.
+
 ## Safety
 
 Only scan assets the user's organization owns or is authorized to test. External domain scans require verification (DNS/file/meta-tag) enforced by the platform — do not try to bypass it.

 - Before filing any report, run the counterevidence pass: argue the strongest case AGAINST the finding, record what you found in the `counterevidence` field, set `confidence` honestly (a static-only trace you couldn't execute is at best `medium`), and state what evidence would change the severity. See the counterevidence and severity-calibration knowledge above.
 - A vulnerability is ONLY considered reported when a reporting agent uses create_vulnerability_report (or create_dependency_report for known-CVE dependency/supply-chain findings) with full details. Mentions in agent_finish, finish_scan, or generic messages are NOT sufficient
 - Reporting and fixing are ONE step, not two: when source is available, the reporting agent derives the concrete fix and files it INLINE via create_vulnerability_report (`code_locations` with `fix_before`/`fix_after` + `fix_pr_body`) — the report is not complete without it. Do NOT report first and then spawn a separate downstream agent to re-derive and re-apply the same patch; that just re-does the analysis and wastes tokens. (Do not silently patch a finding WITHOUT filing a report — the report, with its embedded fix, is the deliverable.)
-- DEDUPLICATION: The create_vulnerability_report tool uses LLM-based deduplication. If it rejects your report as a duplicate, DO NOT attempt to re-submit the same vulnerability. Accept the rejection and move on to testing other areas. The vulnerability has already been reported by another agent
+- DEDUPLICATION: The create_vulnerability_report tool uses LLM-based deduplication. If it rejects your report as a duplicate, DO NOT attempt to re-submit the same vulnerability. Accept the rejection and move on to testing other areas. The vulnerability has already been reported by another agent. If your evidence proves more than the finding it matched (a working exploit where that one had only a static trace, a chain that raises the impact), revise that finding with update_vulnerability_report using the duplicate_of id — never re-file it.
+- REVISING A FINDING: use update_vulnerability_report (report id + the fields you want to replace + update_reason) when you learn something a finding already on file does not carry — you built the PoC after filing it, a chain raised its impact, further testing weakened it, or its counterevidence/remediation/code locations were wrong. Editing a finding needs no duplicate verdict, and it is always better than filing a second report for the same issue. Read the finding first with get_report, and pass only the fields that change.
 - REVIEWING FILED FINDINGS (orchestrator/root agent): use list_reports to see every vulnerability filed so far in this scan (by any agent, root or child) — metadata-first with per-severity counts — and get_report to read one finding in full by its id. These are read-only orchestration tools: the root agent uses them to track coverage, avoid dispatching work on already-covered ground, assemble the finish_scan executive summary, and reason about attack-chaining across confirmed findings. Leaf/specialist agents should NOT call them — just do your assigned testing and file findings. Each entry shows which agent filed it (agent_name), and your own entries are flagged by_you. list_notes/get_note do the same for notes.

+        Discard-on-error, rebuild-on-next-use is the whole discipline here, and it
+        rests on one invariant: **a session object is only ever awaited while
+        healthy.** The moment a call fails, the very next thing this method does,
+        before any other ``await`` including the backoff sleep inside
+        :meth:`_handle_failure`, is dispose that session on this task
+        (:meth:`_safe_cleanup` runs the transport teardown and clears ``_server``).
+
+        Why the ordering is the crux, not a nicety: when a provider returns a non-2xx
+        status mid-call, the streamable-HTTP transport's task group cancels its scope,
+        which cancels this supervising task; the failure surfaces as a
+        ``CancelledError`` and the scope keeps firing (re-raising on every subsequent
+        ``await``) until the session is torn down. Disposing closes the transport's
+        AsyncExitStack, which exits that firing scope. If instead we slept for backoff
+        first, the sleep would re-raise the firing ``CancelledError``, escape this
+        method, and kill the supervising task, leaving the slot wedged with
+        ``is_dead`` False forever. Disposing first is what turns a failure into a
+        returned value and keeps the task alive to rebuild on the next attempt.
+
+        The rebuild itself happens lazily at the top of the loop: once a failure has
+        set ``_server`` to None, the next iteration builds a fresh session (guarded by
+        :meth:`_reconnect`) and retries the operation on it. A permission or protocol
+        failure from a call returns immediately after disposal because it describes
+        that request, not the session. A genuine shutdown (``_closing``) and a real
+        external cancellation still propagate; only the transport's teardown
+        cancellation is contained.

+
+        Why this is delicate: the streamable-HTTP transport holds an anyio task group
+        whose cancel scope was entered on this supervising task. When a background POST
+        got a non-2xx status the SDK cancelled that scope, and until the scope is
+        exited every ``await`` on this task re-raises ``CancelledError``.
+        ``server.cleanup()`` closes the AsyncExitStack that runs the task group's
+        ``__aexit__``, and that ``__aexit__`` is exactly what exits the scope and stops
+        the firing; it also absorbs the scope's own cancellation internally, so the
+        common case returns cleanly. A stray ``CancelledError`` can still surface,
+        though, and ``contextlib.suppress(Exception)`` would let it through because
+        ``CancelledError`` is a ``BaseException``, not an ``Exception``.
+
+        So we catch ``CancelledError`` explicitly. During a real shutdown
+        (``_closing``) that cancellation is the run going down and must propagate, so
+        we re-raise it. Otherwise we absorb it and retry the close a bounded number of
+        times: if a cleanup was interrupted before the exit stack finished unwinding,
+        closing again continues from where it left off (the stack pops one callback at

+
+    Use this when you learn something a filed finding does not yet carry:
+
+    - You built the working exploit after filing the finding on static
+      evidence, so the PoC and the confidence change.
+    - You chained the finding with another one and the real impact is
+      higher, so the impact narrative and the CVSS vector change.
+    - Further testing narrowed or weakened the finding, so the severity
+      must come down.
+    - Counterevidence, remediation, or a code location was wrong or
+      incomplete.
+
+    This is not deduplication. You do not need a duplicate verdict to
+    revise your own finding, and you must not file a second report for a
+    finding you can revise. Call ``list_reports`` or ``get_report`` first
+    to find the id and read what the report already says.
+
+    Pass only the fields you want to replace. Every other field stays as
+    it is. Reporting rules of ``create_vulnerability_report`` apply to
+    every field you pass, including the markdown and tone rules.
+
+    Notes on specific fields:
+
+    - ``cvss_breakdown`` replaces the whole vector. The score and the
+      severity are recalculated from it, so pass all 8 metrics. On a
+      dependency finding it replaces the contextual rating and needs
+      ``contextual_cvss_reasoning`` with it. Pass the reasoning alone to
+      correct only the explanation of the rating already on file.
+    - A dependency finding never carries ``endpoint``, ``method`` or a PoC.
+      File a proven exploit of the package as its own report.
+    - A field that only explains another field is dropped when the field
+      it explains changes and you pass no replacement. Pass
+      ``confidence_rationale`` with a new ``confidence``, and
+      ``severity_change_conditions`` with a new ``cvss_breakdown``.
+    - ``code_locations`` replaces the whole list. A location carrying
+      ``fix_after`` needs ``fix_verification``.
+
+    The report keeps its id, its original author, and its filing time. The
+    revision is recorded in the report as update history, so state the
+    reason plainly.
+
+    Args:
+        report_id: Id of the report to revise (format ``vuln-NNNN``).
+        update_reason: What you learned that the report does not yet
+            carry, in one or two sentences.
