verify

verify is a skill for Claude Code from cwinvestments/memstack. It costs 71 tokens per session (2,079 once invoked), scanned A, original, MIT.

A project check runner that executes the repository's configured verification commands and reads the resulting receipt. It is used to determine whether completed changes pass the available checks.

In plain words
What is it for?
Use it before finishing or committing changes, or when you need to know whether the project's configured checks pass.
Why use it?
Code can appear finished while tests or other repository checks still fail. Running the defined check chain provides evidence before reporting the work as done.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/verify.py run --task-id <session-id>.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

verify 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 2d 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.

✅ Verify: Checking Work...

Run the project's checks, write a receipt, read what it says.

Activation

When this skill activates, output:

✅ Verify: running the check chain...

Then follow the protocol below.

Context Guard

Context Status Priority
Tracked changes are finished and about to be reported done ACTIVE, run the chain P1
User asks "does it pass", "verify this", "is this ready" ACTIVE, run the chain P1
About to commit ACTIVE, a receipt costs less before the commit than after P1
User is mid-task, still editing DORMANT, a receipt for a half-finished tree ages out the moment the next edit lands n/a
Read-only audit or investigation DORMANT, nothing changed, so there is nothing to verify n/a
Edits left no tracked change (new untracked files only) DORMANT, the gate does not see untracked files and neither does the chain n/a
Repo where verify list detects nothing DORMANT, but read NOTHING_DETECTED below before concluding this n/a

What the CLI actually detects

scripts/verify.py detects three families and nothing else. Anything outside this list goes unchecked, so a passing receipt is not a claim that the project is sound:

Family Detected when Runs
npm package.json has a scripts entry named test, lint, typecheck or build npm run <script>, one check per script, in that order
pytest pytest.ini, or pyproject.toml with a [tool.pytest] section, or a tests/ directory python -m pytest -q
ruff ruff.toml, .ruff.toml, or pyproject.toml with a [tool.ruff] section ruff check .

A detected check that cannot run becomes a SKIP carrying its reason: npm missing from PATH, node_modules absent, pytest not importable, ruff not installed. A SKIP is not a pass, because nothing ran.

Run python scripts/verify.py list to see the chain without executing it.

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.

verify is a skill published in the GitHub repository cwinvestments/memstack (419 stars, last pushed today), licensed MIT. It adds 71 tokens to every session and 2,079 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
