verification-before-completion — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited verification-before-completion (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

<!-- Adapted from obra/superpowers — Tessera compliance check (tessera-verify) added as final gate -->
Claiming work is complete without verification is dishonesty, not efficiency.
Core principle: Evidence before claims, always.
Violating the letter of this rule is violating the spirit of this rule.
NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCEIf you haven't run the verification command in this message, you cannot claim it passes.
If tessera MCP is configured AND a plan was registered with `plan_save` — run `tessera-verify` before any other verification:
1. Run the tessera-verify skill
2. Review the compliance report:
- All plan checklist items should be marked done
- All target files should appear in git diff
3. If items are missing: complete them before proceeding
4. Only after tessera-verify is clean: run unit tests + linterThis closes the loop between what was planned and what was built.
BEFORE claiming any status or expressing satisfaction:
1. IDENTIFY: What command proves this claim?
2. RUN: Execute the FULL command (fresh, complete)
3. READ: Full output, check exit code, count failures
4. VERIFY: Does output confirm the claim?
- If NO: State actual status with evidence
- If YES: State claim WITH evidence
5. ONLY THEN: Make the claim| Claim | Requires | Not Sufficient |
|---|---|---|
| Tests pass | Test command output: 0 failures | Previous run, "should pass" |
| Linter clean | Linter output: 0 errors | Partial check, extrapolation |
| Build succeeds | Build command: exit 0 | Linter passing, logs look good |
| Bug fixed | Test original symptom: passes | Code changed, assumed fixed |
| Requirements met | Line-by-line checklist | Tests passing |
| Plan complete | tessera-verify: all items done | Checklist looks done visually |
Tests:
Run test command → See: N/N pass → "All tests pass"
NOT: "Should pass now" / "Looks correct"TDD Regression:
Write → Run (pass) → Revert fix → Run (MUST FAIL) → Restore → Run (pass)
NOT: "I've written a regression test" (without red-green verification)Plan compliance:
Run tessera-verify → See: all items complete → "Plan requirements met"
NOT: "I implemented all the tasks"No shortcuts for verification. Run the command. Read the output. THEN claim the result.
