Subject: [PATCH 1/8] feat(readmevalidation): add online skill source
 verification

Adds a READMEVALIDATION_ONLINE=1 mode to cmd/readmevalidation that
shallow-clones every owner/repo@ref declared in
registry/<namespace>/skills/README.md and verifies:

- every catalogue override slug exists upstream as skills/<slug>/SKILL.md,
- each upstream SKILL.md has the required name and description frontmatter
  per the agentskills.io v0.2.0 specification,
- no slug is provided by more than one source within the same namespace.

The mode is off by default so go run ./cmd/readmevalidation keeps working
without network access. CI enables it when network is available.

Lifts the shallow-clone shape from coder/registry-server/cmd/build/skills.go
so the verifier matches what the deploy pipeline will actually ingest.
Branch-only refs for now, matching that pipeline's current behavior.

Subject: [PATCH 2/8] chore(scripts): add scan-skill-sources.sh

New helper that walks every registry/<namespace>/skills/README.md, extracts
each unique owner/repo@ref from the YAML frontmatter, and runs
NVIDIA SkillSpector over the upstream GitHub URL. One SARIF file per source
is written to ./sarif (configurable via the first positional argument).

The script does not gate on findings. It exits non-zero only when
skillspector itself crashes. Severity gating lives in the workflow so
the deploy policy is visible alongside the deploy step.

Subject: [PATCH 3/8] ci: gate PRs and deploys on skills catalogue and
 SkillSpector scan

Extends the existing validate-readme-files CI job with an online phase
that runs cmd/readmevalidation with READMEVALIDATION_ONLINE=1 when the
PR touches skills paths. Adds a scan-skills job that downloads and runs
NVIDIA SkillSpector over every declared upstream source and uploads
SARIF to GitHub Code scanning, failing on findings at the error level.

Refactors deploy-registry into three jobs:

- verify: runs the same online validator + SkillSpector before deploy.
- deploy: now needs: verify, so gcloud builds triggers run only fires
  when the catalogue is consistent and the scan is clean.
- open-issue-on-failure: posts to a single rolling tracker issue
  (label skills-gate) via JasonEtco/create-an-issue with update_existing,
  so repeat failures update the same issue rather than spamming.

A dorny/paths-filter step drives both the online phase and the scan-skills
job so PRs that do not touch skills pay no extra cost.

+name: Skills deploy gate failed
+about: Auto-opened by the deploy-registry verify job when catalogue or scan fails.
+title: "[skills-gate] Catalogue or scan failure blocking deploy"
+labels: ["skills-gate"]
+---
+
+The pre-deploy verify job for the agent-skills catalogue failed.
+Most recent run:
+
+{{ env.WORKFLOW_URL }}
+
+Trigger: `{{ env.RUN_TRIGGER }}`
+
+This is a single rolling tracker issue. The deploy workflow updates the
+same open issue on every subsequent failure until it is closed. Closing
+this issue without fixing the underlying problem reopens (or creates)
+the next time the gate fails.
+
+Likely causes:
+
+- A `sources[].skills[<slug>]` override in `registry/<namespace>/skills/README.md`
+  no longer matches a `skills/<slug>/SKILL.md` upstream (renamed,
+  deleted, or moved).
+- A declared `owner/repo@ref` no longer clones (repo renamed, deleted,
+  flipped to private, or the branch ref is gone).
+- An upstream `SKILL.md` is missing the required `name` or `description`
+  frontmatter per the agentskills.io v0.2.0 specification.
+- A SkillSpector critical-severity finding on upstream content. Open
+  alerts are listed under the repository's Security tab, Code scanning.
+
+See the run logs and any new Code scanning alerts for specifics, then
+land a PR that updates the catalogue or the upstream source repo.

Subject: [PATCH 4/8] fix: address CI feedback for skills gate

- Drop go-git/v5 dependency and use the system git binary via
  exec.Command. The library pulled go 1.25.0 transitively, breaking
  golangci-lint v2.1.6 which is built against go 1.24.
- Apply prettier-plugin-sh formatting to scan-skill-sources.sh.
- Disable actions/setup-go's default module cache in the deploy
  verify job to satisfy zizmor's cache-poisoning rule on jobs that
  hold security-events: write.

Subject: [PATCH 5/8] fix(ci): install SkillSpector from pinned git SHA

SkillSpector is not on PyPI yet, so the install must reference the
NVIDIA/SkillSpector repository directly. Pinned at commit
2eb844780ab163f01468ecf142c40a2ec0fcaec0 to keep the policy
reproducible. Will switch to a pip-published version when one ships.

Also bumps actions/setup-python from v5.6.0 to v6.2.0 to get off the
deprecated Node 20 action runtime, and pins the latest pip before
installing skillspector so its hatchling build env has the recent
packaging release that supports the SPDX license expression in its
pyproject.toml.

Subject: [PATCH 6/8] fix(scan): keep going on findings, gate only on missing
 SARIF

SkillSpector exits non-zero when its scan finds anything to report,
even though it still writes the SARIF file. Treating that as a crash
short-circuits SARIF upload and prevents the workflow's severity jq
step from making the policy decision. Inverts the check: scan_failed
is now set only when the SARIF file is missing or empty, which is
the genuine 'tool crashed' signal.

Subject: [PATCH 8/8] ci(skills): start SkillSpector gate in warn-only mode

SkillSpector flags 13 error-level findings against coder/skills@main,
all in the intentionally credential-handling setup skill (GitHub
device-flow scripts and references). These are real patterns
matching SkillSpector's PE3 'Credential Access' and E2 'Env Variable
Harvesting' rules, but they describe expected behavior for an
installer skill rather than a vulnerability.

Initial policy is warn-only: SARIF still flows to Code scanning so
the findings are visible on PRs, the severity gate still runs and
prints, but continue-on-error keeps the workflow green. A follow-up
PR can either tune the rules in coder/skills, add SkillSpector
suppressions, or flip continue-on-error to false to make the gate
strict.

Also drops the debug upload-artifact step now that the SARIF shape
is known.
