Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00087 | $0.02474 |
| Opus 5.5 | $0.00035 | $0.00990 |
| Sonnet 5.5 | $0.00017 | $0.00495 |
| Haiku 4.5 | $0.00009 | $0.00247 |
Grade A, and why
unit-test-validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unit Test Validator
Audit unit test files to ensure they comply with every rule the unit-test-writer enforces.
Read-only: produce a compliance report; never modify test or production files, never execute
tests (static analysis only).
The full rule set is in
../unit-test-writer/references/unit-rules.md— validate against it. Build its project profile from the project'sGATES.mdfirst: it says which suites, runner and language the rules apply to here, and names the project's own rules file, which is audited too. The suite's language file,../unit-test-writer/references/languages/<language>.md, is part of the rules: resolve the language asunit-rules.md("Language") says, and read that one file.
Scope: the unit suites the project profile names. Out of scope, reported as such: a file of an integration, e2e or visual suite.
INPUT
test_file_path(required) — test file or directory.checklist_file_path(optional) — the checklist, for coverage cross-reference; when absent, look for it next to the test file (its extension replaced by.unit-test.md) and in eachdocs/<feature-id>-<kebab>/folder whose checklist names the test file; when none is found, report checklist alignment as not verified.target_file(optional) — the source under test, to verify coverage completeness; when absent, the source the test file loads the unit from.language(optional) — the suite's language; when given, it wins over what the profile and the repository say.severity_filter(optional) —critical|major|minor(default: all).
OUTPUT
A compliance report (English): the project profile it applied (a few lines), summary counts,
overall verdict — PASS = 0 critical and 0 major (minors are listed, not counted against it);
PASS WITH WARNINGS = 0 critical and ≥1 major; FAIL = ≥1 critical — each violation
([SEVERITY] Rule-ID, location, description, expected, found, fix), the rules not verified or not applicable with the cause
of each, coverage analysis, and positive findings. When dispatched, the verdict is the signal the caller consumes.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

unit-test-validator is a skill published in the GitHub repository dayvisonassis/sdd-skills (3 stars, last pushed 16d ago), licensed MIT. It adds 87 tokens to every session and 2,474 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
