Stacked on #505 (feat/a11y-app-native-and-links) → #504 → #503: this PR's diff shows only its own two commits.

Why

After #504 and #505 an agent can read any App Accessibility build it has an id or link for. It still cannot find one: "what did the last run of the checkout app find?" had no way to be answered. And the reports people record by hand on the dashboard (the mobile Workflow Analyzer) were not readable at all.

What

App Accessibility's lists, as capabilities (no new tool): capability/app_accessibility.capability-index.json adds an app_accessibility product to the capability registry, reached through searchCapability / invokeCapability like TRA and Test Management:

• list_app_accessibility_projects: the account's projects newest first, or a search by name.
• list_app_accessibility_builds: a project's builds newest first, with the th_build_id fetchAccessibilityIssues reads, status, report_status, app, framework and issue counts; filters by build name, user, test health, time window and app.
• list_manual_app_accessibility_reports: manual reports newest first, with the report id, app, status and issue counts.

These are documented access-key reads with nothing to add on top, which is what the registry is for; a first version shipped them as a listAppAccessibilityReports tool, which this PR no longer adds. Authored from the controllers, with the traps the API docs leave out in each capability's guidance: the projects list reads page (the docs say page_number) and has no page-size ceiling; build_name searches only the project's 500 newest builds; an empty list answers 404 ("No builds found" / "No reports found"); manual reports' created_between is echoed but never filters and user_id applies to admins only, so neither is offered.

fetchAccessibilityIssues reads manual reports (appReportId, or the /report/{id} dashboard link as reportUrl)

• Issues come inline from the report's scanned screens, one row per element, most severe first, paged like the rest.
• Read from the dashboard's own screens (app_scanner/{id}/snapshot?hide_duplicate_issues=true) when that route takes the access key (browserstack/app-accessibility#2803): the count is then the dashboard's, duplicates left out, and each issue names its element, fix and measurements. Until that ships the route answers a key with a login redirect, and the issues come from the Manual Reports API as before: every occurrence, which it does not mark as duplicates, with the dashboard's own count stated next to it.
• A report that has not ended reads as in_progress and is waited on like the other sources.

Routing text: messages that need a report or project id point at the capability functions' lists; docs/TOOLS.md updated.

Changes after the isolated evals

• An empty listing is not an error. The API answers an empty list with 404 ("No builds found") for access-key callers; each list capability's guidance says so.

Changes after review

• A failed project search is reported as the failure (401/403/500), not as "No project named …". Only the API's "No … found" 404 means no match. The native-build link mapping uses the same search and gets the same behaviour.
• The lists moved to the capability registry (above), and the listing tool was dropped. Every capability was invoked live through invokeCapability: projects (by name and paged), builds (plain and by name) and manual reports return what the index declares; the 404/400 answers match their guidance; check-contract.py is clean. The isolated evals' listing cases (projects, latest run of a project, recent manual reports, builds by name) pass through the capabilities.
• Manual reports read through the dashboard's screens when allowed (above), with the fallback verified live.
• docs/TOOLS.md says the tool waits for a finished run's report to process, and reads a run still in progress as it is.

Verified

• npm run build: lint, prettier, 1444 tests, tsc.
• Against production through the built code: the project list, a project's builds, the manual report list, a manual report link, its status and its issues (144 occurrences; the dashboard counts 97, 47 duplicates), and the near-match message. Tests use made-up ids.
• The manual reports API answers at /api/v1/reports on api-app-accessibility.browserstack.com; the documented /api/accessibility/v1/reports path returns 404 in production. Worth a docs fix.

🤖 Generated with Claude Code

Changes after review (Shreyas)

• A dashboard screens page that fails after the first falls back to reading the report in full from the Manual Reports API, rather than returning the part read as the whole.
• The Manual Reports API's issue pages fail with their page and status. The report lookup treats only a 404 as an unknown report (checked live).
• A report with more screens than the page limit says how many were read.
• Checked live: the dashboard route's 302 carries no Location, so the access key never leaves the API host.
• npm run build passes: 1459 tests.

Summary by CodeRabbit

• New Features
  • Retrieve issues from manual App Accessibility reports, including scan and device details, issue occurrences, duplicate and hidden-issue counts, processing status, and dashboard links.
  • Select manual reports by report ID or dashboard link; reports with no scanned screens and no ongoing processing return a no-issues message.
  • Browse App Accessibility projects, builds, and manual reports, with optional name filtering and configurable result limits.

Merge Risk: 🔵 Low · up to 8dbba

Build listing can give misleading guidance during an API failure, and the documentation overstates when issue fetching waits. These bounded issues do not prevent merging, but should be corrected.

Security architecture risk: 🟡 Moderate · up to 8dbba

Project-search errors can return externally supplied names outside the protection used for normal results, creating a conditional prompt-injection path. Requests remain read-only and reuse existing credentials, but name-author permissions and account isolation are not fully established.

Retained concerns

• Medium · security · inferred: The new project-search recovery path places API-provided near-match names in plain agent-facing error text, outside the untrusted-data envelope used for successful results. If another actor can influence those names, a partial-name lookup can introduce stored directives into the agent’s instruction context. Name-author permissions and downstream effects are unverified; exact matching and read-only metadata do not isolate the emitted text.

Security review details

Security Blast Radius

• inferred — Discovery expands exposure from already-known report identifiers to the project and report metadata returned for the configured credentials. Backend authorization determines the accessible account and asset scope; the client source does not establish cross-account isolation. Any agent-level consequence of malicious returned text also depends on downstream capabilities not supplied here.

Security Findings and Attack Paths

• inferred — The conditional attack path is a controlled stored project name, followed by a partial-name lookup with no exact match, followed by unwrapped candidate-name interpolation in the public tool error. The text flow is observed, but attacker naming authority and successful agent redirection are not established. Earlier native-build errors also interpolated names; the PR adds a discovery-triggered path over matching projects.

Trust Boundaries and Controls

• observed — Manual dashboard links are host-checked before extracting an identifier, and report identifiers and name filters are encoded into fixed request targets. Exact project matching prevents selecting a near-match project for build retrieval. These controls constrain routing and selection but do not isolate candidate names subsequently emitted in errors.

Hardening Proposals

• proposed — Preserve the same external-data boundary during recovery as during successful responses: return project suggestions as isolated data while keeping server-authored error instructions separate.

Review: #506

No security issues found. The only CI status is CodeRabbit (skipped).

Medium

• dashboardScreens: a failure on page 2+ returns the partial list as success (deduplicated true), with total_issues below dashboard_count and no warning. Truncation at MAX_SNAPSHOT_PAGES (20) isn't reported either. Fall back to the manual API or throw, and surface screens_read.
• manualApiScreens: no raise_error:false and no resp.ok check, so a failed /issues fetch can read as "0 issues". Throw HTTP <status> on non-OK, including mid-pagination.
• (unverified) it probes the undocumented dashboard route app_scanner/<id>/snapshot with the access key on every call (currently 302). Confirm the Authorization header isn't forwarded across origins, and note the silent behaviour change once the route starts accepting the key.

Low-Medium

• PROCESSING_STATUSES now includes in_progress globally, which could make other sources wait. Scope it to the appReport source.

Low

• manualReportIdFromDashboardLink regex [0-9a-f-]{36} isn't a UUID regex (the tool-level zod is stricter).
• Every cursor page refetches all screens.
• listAppBuilds: dashboard_link can contain "undefined", the "Did you mean" text embeds unwrapped project names, and ordering/build_name semantics/single-page listing are unverified.
• projectId() now throws on non-404 failures, so feat(accessibility): App Accessibility checks on native builds, and App Automate links #505's buildOfNativeBuild propagates a raw error.
• Missing tests: page 2+ failure, /issues non-OK, in_progress waiting, executeListAppAccessibilityReports errors.

AI-assisted read-only review of the diff. Items marked (unverified) were not checked against the live APIs.

[Aaryan430]

Thanks @sarve-shreyas. Addressed in b479db6 (with the updated #505 merged in):

• Medium (dashboardScreens): if a page after the first fails, the partial list is no longer returned. The report is read in full from the Manual Reports API instead, so deduplicated is false and the dashboard's count is stated next to it. When a report has more screens than MAX_SNAPSHOT_PAGES covers, the answer now gives screens_read and says "Only the first N of the report's M scanned screens were read…", the same as for App Automate builds.
• Medium (manualApiScreens): it now sets raise_error: false, and any non-OK page throws Could not read page N of manual report …'s issues …: HTTP <status>, including mid-pagination. manualReport now treats only a 404 as an unknown report. Checked live: an unknown id is 404 on the details and on /issues, and a bad key is 401.
• (unverified) the dashboard-route probe: checked live. The route answers an access key with a 302 whose body is {"success":false,"message":"redirect_to_login",…} and which has no Location header. Nothing follows it, so the Authorization header never leaves api-app-accessibility.browserstack.com. Separately, follow-redirects 1.16.0 (via axios 1.19.0) drops Authorization on a cross-host redirect anyway. The behaviour change once browserstack/app-accessibility#2803 ships is intended and shows in the answer. It goes from "N issue occurrences … the dashboard counts M" to "N issues … duplicates left out", and the PR description says so. It costs one request per read until then.
• Low-Medium (in_progress): nothing waits on it. Only WAIT_STATUSES (finalizing, rule_processing) are waited on. PROCESSING_STATUSES decides the "issues are still being added" note and whether the export link is cached. Of the sources, only a manual report reports in_progress. Left as is.
• listAppBuilds and the other listing items no longer apply. The listing tool was dropped, and the lists are capabilities in the registry.

Build passes: lint, prettier, 1459 tests, tsc. I also read a real manual report through the built code, along with an unknown id and a bad key.
