Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00450 |
| Opus 5 | $0.00000 | $0.00225 |
| Sonnet 5 | $0.00000 | $0.00090 |
| Haiku 4.5 | $0.00000 | $0.00045 |
Grade A, and why
lint-and-validate 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 5d 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.
This is a copy
84% identical to lint-and-validate — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Lint and Validate Skill
MANDATORY: Run appropriate validation tools after EVERY code change. Do not finish a task until the code is error-free.
Procedures by Ecosystem
Node.js / TypeScript
- Lint/Fix:
npm run lintornpx eslint "path" --fix - Types:
npx tsc --noEmit - Security:
npm audit --audit-level=high
Python
- Linter (Ruff):
ruff check "path" --fix(Fast & Modern) - Security (Bandit):
bandit -r "path" -ll - Types (MyPy):
mypy "path"
The Quality Loop
- Write/Edit Code
- Run Audit:
npm run lint && npx tsc --noEmit - Analyze Report: Check the "FINAL AUDIT REPORT" section.
- Fix & Repeat: Submitting code with "FINAL AUDIT" failures is NOT allowed.
Error Handling
- If
lintfails: Fix the style or syntax issues immediately. - If
tscfails: Correct type mismatches before proceeding. - If no tool is configured: Check the project root for
.eslintrc,tsconfig.json,pyproject.tomland suggest creating one.
Strict Rule: No code should be committed or reported as "done" without passing these checks.
Scripts
| Script | Purpose | Command |
|---|---|---|
scripts/lint_runner.py |
Unified lint check | python scripts/lint_runner.py <project_path> |
scripts/type_coverage.py |
Type coverage analysis | python scripts/type_coverage.py <project_path> |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

lint-and-validate is a skill published in the GitHub repository diillson/chatcli (90 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 450 tokens. A static security scan graded it A with 0 findings. It is 84% identical to lint-and-validate, differing in 4 lines, and is treated as a copy.
