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 | $0.00070 | $0.00383 |
| Opus 5 | $0.00035 | $0.00192 |
| Sonnet 5 | $0.00014 | $0.00077 |
| Haiku 4.5 | $0.00007 | $0.00038 |
Grade A, and why
lint 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.
What it actually says
Linting
Run the project's linter/formatter — detect it, don't assume a toolchain.
Detection
Prefer a task the project already defines, then fall back to the ecosystem tool:
| Ecosystem | Check | Fix |
|---|---|---|
| Node | package.json lint (eslint/biome) |
lint:fix |
| Python | ruff check / flake8 |
ruff check --fix |
| Go | golangci-lint run / gofmt -l |
gofmt -w |
| Rust | cargo clippy / cargo fmt --check |
cargo fmt |
| else | Makefile / CI lint target |
— |
Workflow
- Detect the linter (project task first, then ecosystem default)
- Run the check command
- For fixes: run the fix variant (only when requested)
- Report
file:linereferences for all errors
Rules
- Prefer the project's defined task over a raw tool call
- Never invent a linter the project doesn't use
Error Handling
- If no linter or task found → report which config/task is expected and stop
- If the linter exits with parse errors → report each file-level parse error separately with
file:line - If the linter config is missing → report which config is expected and stop
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 is a skill published in the GitHub repository helderberto/agent-skills (14 stars, last pushed 4d ago), licensed MIT. It adds 70 tokens to every session and 383 once invoked, about $0.0003 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 2026-08-30.
