A full project verification routine that runs tests, checks installation and removal, inspects package contents, and looks for disallowed logging or hardcoded paths.

Use it to run the test suite, verify the CLI install cycle, check status-line output, confirm the npm package includes and excludes the right files, and report which checks passed.

It catches broken workflows, packaging mistakes, unsafe path assumptions, and code-quality problems before release.

verify — Skill for Claude Code by yusufalikync/ccs

Install

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.

Clone the repo

git clone --depth 1 https://github.com/yusufalikync/ccs

Per session 16 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 336 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00016	$0.00336
Opus 5.5	$0.00006	$0.00134
Sonnet 5.5	$0.00003	$0.00067
Haiku 4.5	$0.00002	$0.00034

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 1mo 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.

What it actually says

Verify

Run all checks in sequence and report results.

Instructions

1. Smoke tests

npm test

All tests must pass.

2. Install cycle

node bin/cli.js install
node bin/cli.js status
node bin/cli.js uninstall
node bin/cli.js status

After install: status should show ACTIVE
After uninstall: status should show NOT INSTALLED

3. console.log check

Grep scripts/statusline.js for console.log. It must NOT contain any — only process.stdout.write() is allowed.

4. Package check

npm pack --dry-run

Verify these are included: bin/cli.js, src/, scripts/statusline.js. Verify scripts/smoke-test.js is NOT included (excluded by design — only scripts/statusline.js is in the package).

5. No hardcoded paths

Grep src/ files for hardcoded ~/.claude or /tmp/ paths. All paths should come from src/paths.js or os.tmpdir().

Output

Report each check as:

PASS: Check description
FAIL: Check description — what went wrong and how to fix

Final summary: X/5 checks passed.

Changes

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 yusufalikync/ccs (3 stars, last pushed 6mo ago), licensed MIT. It adds 16 tokens to every session and 336 once invoked, about $0.0001 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.
