Problem

While reviewing a VR run today, I followed the triaging-visual-review-runs skill, gave a verdict on two diffs, and told the user they had to go approve in the web UI. The skill said: "Do not approve or tolerate snapshots from this skill — those endpoints are intentionally not exposed as MCP tools yet." The write tools have since landed (visual-review-runs-approve-create, visual-review-runs-tolerate-create), so that instruction is now misdirecting agents away from a perfectly good action.

Changes

Update products/visual_review/skills/triaging-visual-review-runs/SKILL.md:

  • Drop the "all read-only" framing in the intro.
  • Split the Tools table into read tools and write tools, with the call-shape gotchas I hit (approve_all vs explicit snapshots, new_hash = current_artifact.content_hash, commit_to_github, snapshot_id-not-run-id for tolerate).
  • Document the 409 stale_run recovery path — approving a stale run silently fails, and the fix is to list runs by PR number and pick the newest one. A successful approval usually triggers a fresh CI run, which is expected.
  • In What NOT to do, replace "never approve from the skill" with "never approve without explicit user confirmation."

How did you test this code?

Agent-authored. I'm an agent — no manual UI testing performed. Verified by:

  • Calling posthog:exec search visual-review and confirming the two write tools are present.
  • Calling info on both visual-review-runs-approve-create and visual-review-runs-tolerate-create to confirm the input schemas match the call shapes I documented.
  • Hitting the 409 stale_run path live during the session that motivated this change — the recovery flow described in the skill is what I actually had to do.

No automated tests touched; this is a markdown-only change to a skill file.

Publish to changelog?

no

Docs update

Not user-facing — internal agent skill only.

🤖 Agent context

Authored by PostHog Code (Claude Opus 4.7) in the session referenced via Task-Id in the commit trailer. Trigger: I noticed the stale instruction mid-session while triaging PR #60396's VR run. Paul confirmed in chat that the write tools had landed recently and asked me to update the skill.

No code logic changes — markdown edits to a single SKILL.md file. The plugin copy under `~/Library/Application Support/.../plugins/posthog/skills/...` will re-sync from this source on next plugin update.


Created with PostHog Code

The triaging-visual-review-runs skill still said approval and toleration
were not exposed as MCP tools, so the agent kept redirecting users to
the web UI. The write tools landed; update the skill to use them.

Comment thread products/visual_review/skills/triaging-visual-review-runs/SKILL.md Outdated
The approval and toleration call-shape lists omitted the run `id` (the
route parameter), and the toleration note said snapshot_id was used
"not the run id" — which reads as if snapshot_id alone is the whole call.
Both MCP tools require the run `id` in the path *and* their body fields,
so an agent following the skill would hit a missing-route-parameter /
validation failure. List `id` as required in both call shapes and clarify
that snapshot_id selects which snapshot within the run rather than
replacing the run id.
