run-evals — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited run-evals (Agent Skill) and scored it 45/100 (orange). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

The primary manifest — the file an agent reads to learn what this artifact does.
The eval suite verifies three things: the memory system recalls, per-user data never leaks across tenants, and every feature is actually wired and produces the durable DB state it promises. All commands run from the repo root and need a real DATABASE_URL (PostgreSQL + pgvector) and a model provider (ANTHROPIC_API_KEY, Vertex via CLAUDE_CODE_USE_VERTEX=1, or NOMOS_USE_SUBSCRIPTION=true).
On macOS, prefix commands with PGGSSENCMODE=disable if you see GSSAPI connection noise.| Command | What it does |
|---|---|
pnpm eval:audit | The full gate. Agent eval against a throwaway nomos_eval, then the Opus-4.8 label audit + the spec-driven manifest audit, then drops the DB. One process, end-to-end. |
pnpm eval:agent | Agent eval only (no LLM audit), throwaway DB. |
pnpm eval:agent --keep | Run + keep nomos_eval for inspection; also writes a results file. |
pnpm eval:agent --audit-kept | Audit a kept DB (label + spec audit) without re-running the eval, then drop it. |
pnpm eval:agent --clean | Drop a kept nomos_eval. |
pnpm eval:recall | Seed facts, probe retrieval, score recall@5 (regression guard). |
pnpm check:isolation | Write as two users through the real functions, assert neither sees the other. |
Default to PGGSSENCMODE=disable pnpm eval:audit -- the complete check (eval -> audit -> clean). Then report:
N ran, M failed),AUDIT: PASS/FAIL -- the Opus label audit (DB content vs the passing test labels),SPEC-AUDIT: PASS/FAIL -- the manifest audit (wiring + effects vs the feature manifest).To inspect the data instead of dropping it: --keep, then psql "$DATABASE_URL" against DB nomos_eval, then --audit-kept, then --clean.
eval/feature-manifest.ts is an INDEPENDENT contract: per feature, its trigger, entry symbols, observable effects (checkable SQL), and invariants. runSpecAudit() in eval/agent-eval.ts checks four layers:
DORMANT.This is the layer that catches dormant code and under-populated columns that no individual test asserts -- the gap the label audit alone cannot see.
Add a FEATURES entry in eval/feature-manifest.ts with:
trigger -- cron (with sentinel) / turn / boot / cli.entry -- the exported symbol(s) a live path must call. Liveness greps these, so each MUST have a real call site or the audit fails.effects -- a count-query sql (expect: "nonzero") for each durable DB effect; mark notExercised: true when the eval does not drive it (evidence-only, never a hard fail). Add a noDoubleEncode guard for any jsonb column.Verify a new entry with pnpm eval:agent --keep, probe the effect SQL against nomos_eval, and only promote an effect to a hard (exercised) check once you confirm it returns nonzero.
