e2e-runbooks — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited e2e-runbooks (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The primary manifest — the file an agent reads to learn what this artifact does.
Verify that a deployed service actually does what it claims when poked from outside, one capability per spec, asserted only on what the running system shows. Each spec has a paired immutable tasks-template, and every execution leaves a timestamped run record with token and duration accounting.

e2e/testing/runs/*.md
!e2e/testing/runs/README.mdThe four README files carry the conventions: what the suite covers, the canary content per fixture, the spec and template format, and the runner contract. The OpenSpec schema ships canonical text for each, and the scaffold templates in the schema repo are the source to copy from when scaffolding by hand.
Every capability test is three files, and the split is what makes a run auditable.
e2e/testing/{N}-{capability}-test.md, the immutable spec. Seven fixed sections. Never edited between runs. Whenbehaviour changes, write a new spec with a new {N}.
e2e/testing/templates/{N}-{capability}-tasks.template.md, the immutable checklist. Mirrors the spec's Prerequisites,Reset, Run and Expected sections as checkboxes.
e2e/testing/runs/{utc-timestamp}_{N}-{capability}-tasks.md, the execution record. Copied from the template at runstart, ticked off as the run progresses, closed with a Result summary, a Verdict, and token counts. Gitignored by default.
Editing a spec to make a failing run pass destroys the record. Fix the system, or write a new spec.
Every spec has these seven sections, in this order, every time.

Additional tasks I did: <anything off-spec>Assert what the user-facing API or the persisted state shows. Never assert on a log substring: logs drift across versions and are not visible from every runner's shell. When a behaviour assertion fails, a log tail is the next diagnostic step, not a pass criterion.
Fail: passes or fails on a string the service may rename tomorrow.
The agent log contains "MCP tool invoked: getCurrentWeather".Pass: asserts the observable consequence, which is only possible if the tool ran.
The response body's `content` field contains a numeric temperature for the requested city.
The response body's `content` does NOT contain "I cannot access live data".Persisted state counts as observable when it is queried directly.
A `docker exec postgres psql ... -c "SELECT count(*) FROM chat_history WHERE user_id='canary'"` returns 2.
A Qdrant scroll on `documents` filtered by `userId=canary` returns exactly 3 points.
A `mc ls local/uploads/canary/` shows the uploaded file with non-zero size.The {N} prefix is chosen at proposal time from what the test needs. Lower numbers run first in a sweep, so a cheap failure stops the expensive tests from wasting a stack.
| N | Setup cost class | Examples |
|---|---|---|
| 1 | No state to reset, no fixtures, single endpoint or tool call | Health check, MCP weather lookup, refusal probe |
| 2 | Single fixture upload, vision model, or document parsing | Image description, inline PDF summarisation |
| 3 | Single-service reset | Cache hit and miss probe |
| 4 | Multi-service reset | Full upload, ingest, retrieve round trip |
| 5+ | Seeded state plus an async background process to observe | Compaction, projection rebuild, event replay |
Pick the lowest unused N that matches the class.
A fixture used by an upload test must contain content unique enough that the model could not have memorised it, so a passing test proves retrieval rather than recall.
Fail: the model can answer from training data, so the test passes with retrieval broken.
fixtures/facts.md: "The capital of France is Paris."Pass: an invented proper noun and a specific number nothing else contains.
fixtures/markdown-canary.md: "The HELENA-DEDUP-CANARY village holds the 17th annual pierogi festival every August 14th."The same principle in other formats: short PDFs with invented product names and specific prices, DOCX recipes with distinctive rest times (47 minutes, not an hour), small images of an uncommon but recognisable subject, audio clips under 60 seconds containing an invented word. Keep every fixture small enough to upload in under two seconds, put them in e2e/fixtures/, and record each one's distinctive content in a table in e2e/fixtures/README.md.
The skill pins no client. Pick one per project and use it across every test.
| Client | When | Notes |
|---|---|---|
| Bruno CLI | REST APIs, multi-step flows, mature collections | Single source of API truth, and the request file is the fixture |
| Hurl | Plain-text HTTP with assertions inside the request file | Lighter than Bruno, with assertions next to the request |
| VS Code REST Client | Human-only execution paths | .http files, no CLI runner |
curl | Single-shot health checks and protocol probes | Use for prerequisite checks inside the spec |
| httpie | Interactive debugging | Not a stored-test format |
For MCP tool tests, drive the request through the agent rather than the MCP server directly, so the assertion covers discovery and routing rather than protocol mechanics alone.
Name each run record with the sweep timestamp and the spec it came from. Use ISO-8601 with colons replaced by hyphens so the filename is safe on Windows, macOS and Linux.

2026-05-12T17-23-36_2-image-description-tasks.mdOne timestamp equals one full sweep, so every record from a sweep shares a prefix and a mixed-timestamp directory reads as partial sweeps. Promote runs to a committed audit trail by adding runs/<YYYY-MM>/ subfolders when the team needs traceability.
The runner, human or agent, follows the same sequence every time.
e2e/testing/runs/ under the sweep timestamp.Start (UTC) as the first action, before the prerequisite checks.End (UTC) once the Verdict is decided.Duration = End - Start as HH:MM:SS, wall-clock for the whole test including prereqs and reset, not justthe API call.
Input tokens and Output tokens with the best available estimate. Leave blank when unavailable rather thaninventing a number.
For more than one test, the main session delegates rather than executing. It orders the specs by {N}, picks one UTC sweep timestamp, and fans out one e2e-runner subagent per spec, refilling the in-flight slots as verdicts return. Isolated context per test, per-test token accounting, and failure isolation are what the fan-out buys.
The default parallel cap is 5, confirmed with the user before each sweep, and conflicting tests serialise below it. The reasoning behind the cap, the concurrency declaration format, and the scheduling algorithm are in references/orchestration.md.
The main session never reads prerequisite output and ticks boxes itself, never invokes an API client directly during a sweep, never edits a spec mid-sweep, and never exceeds the confirmed cap. A single test being debugged can be run inline, since the subagent layer exists for fan-out.
When the service uses the startup-readiness banner from observability-and-logging, the banner's external dependency section is the first stop when a prerequisite check fails. Check it once at sweep start: a [FAILED] row names the dependency to fix, and there is no point running tests against a half-up stack.
