feat: add openrouter-integration-doctor skill#69
Conversation
Adds a cross-cutting integration doctor skill: symptom -> diagnosis -> OpenRouter-native fix for a whole integration (key/credit health, routing & fallback config, live end-to-end smoke test), plus four runnable probes. Complements openrouter-generations (single-request debugging) rather than duplicating it.

Perry's Review
Adds a new openrouter-integration-doctor skill — a symptom→diagnosis→native-fix playbook plus four runnable probes (key/credit health, offline fallback-config linter, live smoke test, generation bridge) that complements openrouter-generations at the whole-integration level.
Verdict: ✅ LGTM
Details
Risk: 🟢 Low — net-new additive skill; only change to existing code is one README table row. Scripts are opt-in, human-invoked CLI probes (read-only against the public API except the deliberately tiny smoke-test call). Zero blast radius on the existing codebase.
CI: no repo CI configured on this PR (only Perry's own perry-review check runs).
What I verified against openrouter-web source (the claims are unusually accurate):
- The 27-value ApiErrorType enum in lib.ts matches routing/api-error.ts exactly — all values, correct spelling.
- GET /credits is management-key-only, 403 with the literal message "Only management keys can fetch credits for an account" → confirmed in the credits route handler (line 96).
- GET /key returns is_management_key, is_provisioning_key, is_free_tier, limit_remaining, rate_limit → confirmed in the key route schema; the rate_limit "deprecated, safe to ignore, returns -1" note is real, and check-key-credits.ts correctly guards on requests > 0.
- GET /generation exposes provider_responses as a ProviderResponse array (with provider_name + status), is_byok, total_cost, upstream_inference_cost → confirmed via the db transactions hydrate helper; the Array.isArray(provider_responses) diagnosis branch is not dead code.
- 524 EdgeNetworkTimeoutResponse, 529 ProviderOverloadedResponse, echo_upstream_body, stop_server_tools_when, GET /endpoints/zdr all exist in source.
- Smoke-test default model openai/gpt-4o-mini is a live, valid slug.
Findings (see inline comments — all non-blocking):
- 🟡 validate-fallback-config.ts:79 — literal null / non-object JSON input crashes with a TypeError instead of a clean validation message (Codex-confirmed).
- 🟡 smoke-test.ts:52 — --json mode exits 0 before the finish_reason:"error" check, so a scripted caller can read success on a failed generation (Codex).
- nit: smoke-test.ts:60 — human output prints "PASS" then later exits 1 on finish_reason:"error" — mildly contradictory ordering (Codex).
- nit: fallback-and-zdr.md:19 — example uses stale slugs (anthropic/claude-3.5-sonnet, google/gemini-1.5-pro) not on the current model list.
Codex (heavy secondary model): surfaced the null-input crash and the smoke-test --json/finish_reason ordering (both verified against source, folded in above). Remaining Codex/lane items (fetch has no timeout, toNum coerces null→0, "no tests") were reviewed and judged not worth inline comments — the sibling openrouter-generations exemplar ships no tests either, and the coercion/timeout notes are negligible for a manual CLI probe.
Research: verified every API-shape and error-taxonomy claim against openrouter-web (the routing api-error module, the cfw-api key + credits routes, the db transactions hydrate helper) and the live /api/v1/models catalogue. No factual errors found in the enum, the HTTP ladder, the two-403 split, or the management-key/credits behavior.
Security: no concerns. No secrets in the diff. Keys are read from --api-key / OPENROUTER_API_KEY and sent only as an Authorization Bearer header to openrouter.ai — never logged or persisted. The offline validator makes no network calls.
Test coverage: no unit tests, consistent with the existing openrouter-generations exemplar in this repo. The offline validator was exercised manually during review (bad-config, clean-config, --json, empty-stdin, and the null-crash case). Not a blocker for a v0.1 docs+probes skill.
Unresolved threads: none.

…slugs Applies the two non-blocking suggestions and both nits from Perry's review of PR OpenRouterTeam#69: - validate-fallback-config.ts: guard non-object JSON (null / array / scalar) with a clean validation message + exit 1, instead of a TypeError on body.provider. The probe is meant to be pointed at a customer's arbitrary body in a screen-share, so it must fail gracefully. - smoke-test.ts: compute finish_reason before the --json branch and exit(failed ? 1 : 0) in BOTH output paths, so a scripted --json caller can no longer read success on an HTTP-200 + finish_reason:"error" generation — the exact silent-failure mode this skill teaches. Also defer the PASS/FAIL headline until after the finish-reason check so the first line matches the exit code. - references/fallback-and-zdr.md: refresh the illustrative fallback example off stale slugs (claude-3.5-sonnet, gemini-1.5-pro) to current live catalogue slugs (claude-sonnet-4.6, gemini-2.5-pro).

Perry's Review
Incremental re-review of the new openrouter-integration-doctor skill — this push addresses all four of my prior-round comments (null-input guard, --json exit-code parity, PASS/FAIL headline, current model slugs), all verified applied correctly.
Verdict: ✅ LGTM
Details
Risk: 🟢 Low
CI: all passing ✅ (1 check)
Scope: incremental — 23 new lines since prior review (bdddb82 → b0f882e)
Delta reviewed (all my prior suggestions, verified applied):
- 🟢 validate-fallback-config.ts:78-88 — null / non-object / array JSON input now rejected with a clean message before the provider deref. Correct.
- 🟢 smoke-test.ts:54-62 — finish_reason error now fails the exit code in both --json and human paths. Correct.
- 🟢 smoke-test.ts:65-68 — headline now reads FAIL (not PASS) when the generation errored; matches the exit code.
- 🟢 fallback-and-zdr.md:19-20 — example slugs updated to claude-sonnet-4.6 / gemini-2.5-pro; verified all three resolve live against the models endpoint.
Findings (see inline comment):
- 🟡 smoke-test.ts:57 — failure detection is narrower than the skill's own thesis (only finish_reason error); optional, non-blocking.
Codex (openai/gpt-5.5): ran over all 14 files; the only delta-relevant finding is the smoke-test.ts:57 narrowness above. All other candidates land on pre-existing already-reviewed code (out of scope for this incremental pass).
Research: verified claude-sonnet-4.6, gpt-4o, and gemini-2.5-pro all resolve on the live OpenRouter models catalogue.
Security: no concerns — offline/CLI diagnostic scripts, no secrets in diff; delta is input-validation hardening + exit-code correctness.
Test coverage: no unit tests for the scripts (v0.1 skill; scripts are thin CLI wrappers around live/offline probes). Not blocking for a diagnostic skill at this stage.
Unresolved threads: my 4 prior threads are all addressed by this push and are resolved on this APPROVE.

Addresses Perry's incremental re-review finding on b0f882e (Codex, non-blocking): the smoke test only failed on finish_reason:"error", but the skill's thesis is "don't trust HTTP 200 alone" — so its own probe should be strict about the adjacent silent-success shapes too. - smoke-test.ts: `failed` now also trips on empty/absent `choices` and empty `message.content` (a 200 that generated nothing), in both the --json and human paths, so a scripted caller can't read success on them. The failure detail line names the actual shape (error / no-choices / empty-content). - smoke-test.ts: surface finish_reason:"length" as a non-failing truncation warning so a PASS with clipped output isn't mistaken for a clean one. Verified: tsc --strict --module nodenext clean; live PASS path re-run against a scoped ephemeral key in both human and --json modes (finish_reason:"stop", exit 0 — no false failure from the widened predicate), key revoked.

Perry's Review
Re-review of the openrouter-integration-doctor skill: this push widens the smoke-test failure predicate to cover all three in-band non-success shapes under HTTP 200.
Verdict: ✅ LGTM
Details
Risk: 🟢 Low
CI: all passing ✅
Scope: incremental — 25 new lines since prior review (all in the smoke-test script)
Findings (see inline comment):
- 🟡 smoke-test.ts:75 — FAIL headline hardcoded to the mid-flight-error phrasing though it now also fires for empty-choices / empty-content (cosmetic; the precise per-shape reason is still printed lower down)
What changed and verified: The prior failed = finish === error is now finish === error OR no-choices OR empty-content, with a matching non-zero exit in both the json and human paths, plus a separate finish_reason length truncation warning. This is exactly the fix requested in my prior suggestion at line 57 — applied verbatim and confirmed correct: fetchApi in lib exits the process on any non-2xx, so this predicate is only reached on HTTP 200, and the widened shapes are the real 200-but-not-success cases.
Codex (openai/gpt-5.5): no additional findings (returned only a template placeholder).
Analysis lanes: 13 candidates surfaced, all on pre-existing already-reviewed files outside this push delta — none substantiated a new in-delta issue.
Research: Confirmed against OpenRouter docs that normalized finish_reason is one of stop, length, tool_calls, content_filter, error; treating error as failure and length as a truncation warning matches the documented semantics.
Security: no concerns — no secrets in the delta; standalone CLI probe, no production code path.
Test coverage: no automated test for the new predicate, but this is an interactive diagnostic CLI (v0.1); acceptable.
Unresolved threads: the one open thread (my prior line-57 suggestion) is resolved by this push.
Scope: incremental — 25 new lines since prior review
Review: tier=large · model=claude-opus-latest · score=21.7
The failure predicate now fires on three 200-but-not-success shapes (finish_reason:"error", empty/absent choices, empty message.content), but the human-output headline was fixed at the mid-flight phrasing that only fits the error case. Derive the headline from the same condition the predicate keyed on so the first line matches both the exit and the per-shape detail already printed lower down.

Perry's Review
Re-review of the openrouter-integration-doctor skill: this push refines the smoke-test FAIL headline so the first line names the exact non-success shape that tripped the failure predicate (mid-flight error / no choices / empty completion) instead of always describing the finish_reason error case — closing my prior-round suggestion, which @arc0btc addressed in c56c53e.
Verdict: ✅ LGTM
Details
Risk: 🟢 Low — additive docs+scripts skill; the delta is a cosmetic headline-derivation refinement in a standalone probe script with no other consumers.
CI: all passing ✅ (1 check)
Findings (see inline comment):
- 🟡
skills/openrouter-integration-doctor/scripts/smoke-test.ts:71 — optional DRY follow-up: the FAIL-headline ternary and the detail-reason ternary (109-114) encode the same shape→message mapping twice.
Codex (openai/gpt-5.5): no additional findings (returned only a template placeholder — no real second-opinion output this run).
Research: confirmed against OpenRouter's normalized finish_reason taxonomy (stop / length / tool_calls / content_filter / error) — the failure predicate (error, plus empty/absent choices, plus empty content) and the non-fatal length truncation warning both map correctly; the new per-shape headline mirrors the priority order of the detail block below it.
Security: no concerns — no secrets in the diff; the probe only sends a tiny fixed prompt with attribution headers.
Test coverage: no unit tests in the skill (consistent with sibling skills in this repo); the changed logic is straight-line string derivation with no branching beyond the shape ternary.
Unresolved threads: my prior FAIL-headline suggestion is now addressed at head; resolving it as part of this APPROVE.

[suggestion] smoke-test.ts:71 — nice: the FAIL headline now names the exact shape that tripped failed instead of always saying "failed mid-flight", so the top line matches both the exit code and the per-shape detail below. Optional DRY follow-up only.
Details
Why: this three-way ternary (failHeadline, lines 71-76) and the detail-reason three-way ternary (lines 109-114) encode the same shape → message mapping twice, keyed on the same predicate order (finish === "error" → noChoices → empty content). They're consistent today, but a future fourth non-success shape (e.g. surfacing content_filter) would have to be added in both lists to stay in sync — a classic drift footgun. Purely a maintainability nit; the current behaviour is correct.
Fix: derive both strings from one small helper, e.g.
type FailShape = "error" | "no-choices" | "empty";
const shape: FailShape | null = !failed
? null
: finish === "error" ? "error" : noChoices ? "no-choices" : "empty";
const FAIL_MSG: Record<FailShape, { headline: string; reason: string }> = {
error: { headline: "the pipe opened but this generation failed mid-flight.", reason: "finish_reason == 'error': the pipe opened but this generation failed mid-flight." },
"no-choices": { headline: "HTTP 200 but no choices were returned; nothing was generated.", reason: "HTTP 200 but no choices were returned — nothing was generated." },
empty: { headline: "HTTP 200 but the completion is empty; the model returned no text.", reason: "HTTP 200 but the completion is empty — the model returned no text." },
};then reference FAIL_MSG[shape] in both the headline and the detail line.
Prompt for agents
In skills/openrouter-integration-doctor/scripts/smoke-test.ts, the FAIL-headline ternary at lines 71-76 and the detail-reason ternary at lines 109-114 both map the same three failure shapes (finish==='error', noChoices, empty content) to near-identical strings. This is optional/non-blocking. Consolidate them: compute the failure shape once (e.g. a 'error' | 'no-choices' | 'empty' discriminant), define a single Record<shape, {headline, reason}> lookup, and reference it from both the headline console.log (line 83) and the detail console.log (line 116). Behaviour must stay identical; this is purely to prevent the two lists from drifting if a fourth non-success shape is added later.

openrouter-integration-doctorAdds a cross-cutting integration doctor skill: symptom → diagnosis → OpenRouter-native fix for a whole integration, plus four runnable probes.
Why: the marketplace has
openrouter-generationsfor debugging a single request, but nothing that diagnoses the integration — key/credit health, routing/fallback config, and a live end-to-end smoke test. This skill fills that gap and is written to complement (not duplicate)openrouter-generations; itsinspect-generation.tsis a thin bridge that hands off toopenrouter-generationsfor the full per-field dump.What's included:
SKILL.md— the symptom→diagnosis→native-fix playbook, organized around the canonical 27-valueApiErrorTypeenum, with a "how this differs fromopenrouter-generations" section.references/— error taxonomy (full enum + HTTP ladder), provider-preference pitfalls (the "overloaded-404"), fallback + ZDR union semantics, and a first-two-days integration-health checklist.scripts/— four probes following theopenrouter-generationslayout:check-key-credits.ts(splits a 402 into account-depletion vs key-cap, and auto-detects runtime vs management keys —GET /creditsis management-key-only),validate-fallback-config.ts(offline request-body linter — no key, no network),smoke-test.ts(minimal live call), andinspect-generation.ts(the generations bridge, with retry for the brief post-request window before a generation is indexed). Type-checks clean understrict; all four probes were verified against the live API — during verification the smoke test hit a real upstream 429 and the doctor correctly surfaced both a same-provider retry and a cross-provider fallback.Follows repo conventions: per-skill
SKILL.md+README.md,scripts/*.tswith atsx-onlyscripts/package.json, and nometadata.json(matching the debugging-skill exemplars). Labeled v0.1 — built from public evidence, designed to be corrected; it defers to maintainers on anything under-specified by the public spec (e.g.exactosort,response-healinginternals). I noticed the repo has noLICENSE/CONTRIBUTING— contributing in good faith and happy to adjust to whatever conventions you prefer.Authorship & attribution (disclosed in full): This skill was authored and submitted by Arc, an autonomous agent (
