Problem

Routine-fired sessions have no gh CLI (gh: command not found), but the skills/agents:

  • built the relay identity as ACTOR="$(gh api user --jq .login)" → with gh absent, ACTOR is empty, so the relay 401s every X-Actor call and a Routine Test Runner can't provision; and
  • did all GitHub reads (PR diffs, checks, dedup, run logs, re-runs) via gh api → all break without gh.

This surfaced on the first real Jira-triggered Test Runner run (the /jira relay endpoint fired the routine end-to-end for the first time; the run then hit gh: command not found). Every prior validation ran in an environment that had gh (interactive sessions / the qa-linode env whose SessionStart hook installs it), so we never exercised the gh-less path.

Fix — MCP-first, gh as a fallback only where present

  • repos skill: new "GitHub access — MCP-first" section = the canonical tool map — get_me, pull_request_read (get/get_diff/get_files/get_commits/get_check_runs/get_review_comments), get_job_logs, actions_run_trigger, list_pull_requests/search_pull_requests, get_file_contents, get_commit, issue_read.
  • Identity (the actual blocker) — linode-docker-provisioning, linode-ha-provisioning, and the jira skill now take ACTOR from the GitHub MCP get_me (.login), set as ACTOR="${ACTOR:-$(gh api user …)}" so a pre-set ACTOR wins and gh is a pure fallback.
  • Routine-critical inline commands → MCP tools: investigator dedup (list_pull_requests) and failed-run logs (get_job_logs failed_only); fb-reporter re-run (actions_run_trigger rerun_failed_jobs).
  • fb-tests / git-diff: MCP-first banner + check-runs/diff via pull_request_read; the detailed gh api recipes stay as a documented fallback where gh exists.

Impact / risk

No behavior change where gh exists (interactive sessions keep working via the fallback). Fixes the gh-less Routine environment so the relay identity gate and GitHub reads work there. Docs/skills only — no product or test-suite code touched.

Routine-fired sessions have no `gh` CLI (`gh: command not found`), but the
skills/agents built the relay identity as ACTOR="$(gh api user --jq .login)"
and did GitHub reads via `gh api`. With gh absent, ACTOR is empty -> the relay
401s every X-Actor call, so a Routine Test Runner can't provision; and all
GitHub reads break. Surfaced on the first real Jira-triggered Test Runner run.

- repos skill: new "GitHub access - MCP-first" section = the canonical tool map
  (get_me, pull_request_read {get,get_diff,get_files,get_commits,get_check_runs},
  get_job_logs, actions_run_trigger, list/search_pull_requests, get_file_contents,
  get_commit, issue_read). gh api is a fallback only where gh exists.
- Identity (the blocker): docker + HA provisioning and the jira skill now take
  ACTOR from the GitHub MCP get_me (.login), set it as ${ACTOR:-$(gh api user…)}
  so a pre-set ACTOR wins and gh is a pure fallback.
- Routine-critical inline commands converted to MCP tools: investigator dedup
  (list_pull_requests) + failed-run logs (get_job_logs failed_only); fb-reporter
  rerun (actions_run_trigger rerun_failed_jobs).
- fb-tests / git-diff: MCP-first banner + check-runs/diff via pull_request_read;
  the detailed gh api recipes stay as a documented fallback where gh is present.

No behavior change where gh exists (interactive sessions); fixes the gh-less
Routine environment.

In @.claude/agents/fb-reporter.md:
- Line 38: Update the FB check polling instructions near the existing Step 1 to
use the GitHub MCP check-run API as the primary path, and guard any gh api
fallback with command -v gh so gh-less Routine sessions continue successfully;
keep the existing failed-job retry behavior unchanged.

In @.claude/skills/fb-tests/SKILL.md:
- Around line 8-12: The Green gate should use GitHub MCP check retrieval as its
primary path when gh is unavailable, with gh api retained only as a conditional
fallback. Update the relevant Green-gate instructions and the fb-tests reference
document to apply identical latest-run selection and fail-closed behavior
regardless of which retrieval path is used.
- Line 12: Update the check-run retrieval instructions around get_check_runs to
request up to 100 results per page and consume every MCP page before applying
the Green gate. Apply equivalent full pagination to the gh api fallback,
preserving the existing latest-run-per-check grouping behavior.

In @.claude/skills/jira/SKILL.md:
- Line 103: Update ACTOR resolution in .claude/skills/jira/SKILL.md:103,
.claude/skills/linode-docker-provisioning/SKILL.md:59, and
.claude/skills/linode-ha-provisioning/SKILL.md:27 to invoke gh only when command
-v confirms it is available, then validate ACTOR before any relay request and
fail closed when it is empty or invalid; apply the same guard and validation
consistently across all five relay blocks, including both teardown blocks.

In @.claude/skills/linode-docker-provisioning/SKILL.md:
- Around line 206-208: Make teardown fail closed: enforce successful 2xx
responses for both destroy requests, and remove retry markers only after
destruction succeeds so failed requests preserve them. Apply this to the
destroy-request flows in .claude/skills/linode-docker-provisioning/SKILL.md
lines 206-208 and .claude/skills/linode-ha-provisioning/SKILL.md line 111, and
update the relay requests in .claude/hooks/session-end-cleanup.sh to use the
same validation instead of suppressing failures with plain curl and || true.

In @.claude/skills/repos/SKILL.md:
- Around line 38-40: Scope every Actions CLI fallback to its target repository:
in .claude/skills/repos/SKILL.md update the generic gh run list, gh run view,
and gh run rerun examples to include -R {owner}/{repo}; in
.claude/agents/investigator.md update the Investigator gh run view fallback to
include -R percona/pmm-qa.
- Line 32: Paginate pull-request retrieval before deduplication: update
.claude/skills/repos/SKILL.md at line 32 and .claude/agents/investigator.md at
line 39 so list_pull_requests uses page/perPage iteration until all pages are
collected, while the gh api fallback uses --paginate with aggregation; preserve
the existing deduplication behavior over the complete result set.

The agent's GitHub credential proxy is repo-scoped (REST only), so a github.com
web page (e.g. an FB Actions run) navigated through it returns a 403 JSON instead
of HTML. Bypass the proxy for github.com hosts (or PW_NO_PROXY=1) with an
explicit --no-proxy-server so Chromium takes the transparent egress-gateway path,
which serves the real page — a bare launch would otherwise inherit the system
proxy and still hit the credential proxy.

Both the proxy and direct egress paths are TLS-intercepted by CAs Chromium's
bundled trust store rejects, so derive SPKI pins for those interception CAs from
the environment's trusted bundle and pass them via
--ignore-certificate-errors-spki-list — trusting exactly those CAs, not a blanket
ignoreHTTPSErrors.

The Jira action button now targets the relay's POST /jira, has the
webResponse 404 → "not onboarded" branch, and was confirmed firing from a
test ticket.

…xy path

Chromium keeps only the last --ignore-certificate-errors-spki-list, so a
per-script PMM-cert flag plus a separate interception-CA flag silently dropped
one set. Combine the caller's pins with the interception CA pins into a single
flag inside proxy.js, and carry the interception pins on the proxy path too (not
just the direct-egress path) so proxy-based browser scripts validate TLS-
intercepted sites under strict verification. pw-screenshot, pmm-ui-login, and
pw-record now pass their PMM pin via spkiPins instead of building their own flag.

Address review on #1191:
- fb-reporter Step 1 and the fb-tests Green gate are now MCP-first (get_check_runs),
  with the gh recipes guarded/labelled as fallback-only; page through all check runs.
- ACTOR resolution across all five relay blocks (jira, both provisioning skills,
  both teardowns) guards gh with `command -v` and fails closed on an empty actor
  instead of sending an empty X-Actor the relay 401s.
- linode-docker teardown removes the local run markers only after a confirmed
  destroy; linode-ha teardown uses --fail-with-body so a failed destroy surfaces.
- repos/investigator: page through all open PRs before dedup, and scope the
  gh run list/view/rerun fallbacks with -R {owner}/{repo}.

…lt to latest

An HA run testing a specific PMM release/RC could set the FB image tag but leave
the chart at its latest-published default — the skill only documented overriding
image.tag and never told the agent where the charts live or how to find the
matching chart version, so it never searched for the correct chart.

- linode-ha-provisioning skill: new "Choosing the chart" step names the charts
  (percona/pmm-ha, percona/pmm-ha-dependencies) and repo, and requires searching
  `helm search repo … --versions` + matching appVersion and pinning chart_version
  before install; the FB section now sets chart_version alongside the image and
  points at `helm show values` for the real image keys.
- create-lke-pmm-ha.sh: log the pinned chart version, and warn (with the latest
  chart/appVersion) when none is set, so an unpinned run is visible in the log
  the relay returns instead of silently installing latest.

An HA feature can span two repos — percona/pmm (image) and
percona/percona-helm-charts (the pmm-ha chart) — and the chart half is often an
unmerged PR/branch. The skill only taught picking a released chart version, so a
run tested a chart change against the released chart and drew a false conclusion
("the chart never sets PMM_HA_NAMESPACE" when the unmerged chart PR adds exactly
that).

- linode-ha-provisioning: new first step — decide whether the change is in the
  image, the chart, or both; search percona-helm-charts for the companion
  PR/branch; and if the chart is part of the change, install that PR-branch chart
  against the returned kubeconfig (git clone -b <branch> + helm upgrade
  charts/pmm-ha) instead of the released one. Released-chart version selection is
  now scoped to image-only changes.
- repos: add percona/percona-helm-charts to the repo map (read/diff only) so the
  chart repo is discoverable.
