Why

The package check can approve resources outside the plugin, overlook incomplete packages, and reject valid consumer selections. A successful check can therefore disagree with what an assistant can actually load.

What

Validate complete packaged resources and preserve the names and selections declared for consumers. Ambiguous or incomplete packages fail before they can be offered for installation.

Related issues: #437, #438, #439, #440, #441 and #442.

Fixes #436

Validation of the implementation in eeb34cb434adf56dfe31e9ca05d0febf0758ddc7: all 313 manifest cases and 24 new discovery regressions pass, together with the package and MCP boundary suites and ShellCheck. The new suite is included in CI by 9471f3779ec4f41e097d2a803cb9609b696321f9 (actionlint passes).

The complete current package validates as a consumer would run it. Deliberately linked resources, manifestless packages, incomplete skills and truncated discovery output refuse; explicit agent selections exclude unselected documents, literal backslashes survive parity checks, and supported MCP names retain their identity in the catalogue. Independent review found two additional omissions within this scope, now covered by regressions and fixed.

This PR implements #437, #438, #439, #440, #441 and #442. They will be closed after the merged package behavior is read back.

Blocker: review-request coordination is unavailable because the GitHub REST API quota is exhausted. The required atomic review-lock helper returned UNKNOWN on #207 at 22:47 UTC; no review request was posted and no gate was waived. CI is also still settling at 9471f3779ec4f41e097d2a803cb9609b696321f9.

Implementation, regression coverage, independent read-only review and local consumer evaluation are complete. This PR remains a draft, and its related issues remain open. Resume by rebinding the current head and base, completing CI, acquiring the review lock, obtaining a substantive current-head review and merging with the exact head pin. No polling loop or background watcher is running.

ShellCheck SC2015 flagged the A && B || C chain in validate_skill_dir. The
condition is unchanged: refuse when the path is not a directory or is a
symlink.

📝 Walkthrough

Walkthrough

The manifest validator now checks package inventories, canonical manifests, and packaged resources, including plugin skills, agents, and MCP configuration. Marketplace comparisons use captured JSON fields, and catalogue parsing accepts nonempty inline-code tokens. New package-discovery tests cover valid and invalid fixtures, and CI runs the test script. Documentation and existing self-tests reflect the updated validation rules.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to cf98c

No actionable issue remains in the selected change; it is mergeable after the normal required checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to cf98c

The changes strengthen package validation without identifying a new security exposure. The new discovery tests run against temporary fixtures with read-only repository permissions. Remaining uncertainty concerns whether installation and consumer behavior fully match the stricter validation rules.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is repository-wide package acceptance and CI execution, not a new tenant-facing endpoint. The validator processes the plugin census, while the new test runs in a job with contents-read permission and checkout credential persistence disabled.

Trust Boundaries and Controls

  • observed — Package-authored paths and resources must pass canonical-layout and regular-file controls before acceptance. Marketplace comparisons use structured JSON values rather than tab-separated field reconstruction, preserving declared values during parity checks.
  • observed — The flagged PATH, FRAME_KIND and REAL_FIND usage implements test-only discovery producers under temporary fixture roots. Those overrides are applied to individual validator test calls; they do not create an alternate production acceptance entrypoint.

Resilience and Maintainability Implications

  • inferred — The inspected transition produces diagnostics and an exit status, not an installation or persistent approval record. Partial inventory production fails acceptance; interruption can leave temporary files but does not strand a newly deployed or privileged package state in this flow.

Comment thread scripts/package-discovery.test.sh Outdated
A rejected fixture passed on any error line, so a fixture refused for an
unrelated reason still counted as covering its boundary. Each one now names
the diagnostic it must produce, and a rejection that names none fails.

Evaluated as a user at cf98ce3a9e518846d8d655e61341486859a9916a. I ran the manifest validation on the real plugin tree (it passes) and the discovery regression suite (24 fixtures pass). I also printed what each of the 16 rejected fixtures reports: each is refused for the boundary it is meant to cover (linked skill, agent, MCP file, manifests, incomplete skill, orphan package, ambiguous MCP names, unlisted resource, incomplete record). CodeRabbit reviewed this head with no actionable comments, CI is green and the one thread is resolved.
