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.

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 | $0.00044 | $0.05838 |
| Opus 5.5 | $0.00018 | $0.02335 |
| Sonnet 5.5 | $0.00009 | $0.01168 |
| Haiku 4.5 | $0.00004 | $0.00584 |
Grade A, and why
set-up-linters 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 23d 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 — 269 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Set-Up Linters
Detect the project type, recommend appropriate linters and formatters, install them, generate sensible default configs, create .editorconfig, and optionally wire up CI.

lint-and-fix
Workflow
1. Detect Project Type
Scan for language and file-type markers using Glob. Exclude dependency directories from all searches to avoid false positives from vendored code: node_modules/, .yarn/, .lake/ (Lean dependency/build directory, including .lake/packages/**), and any others the project carries.
Use both files and directories as signals:
| Marker(s) | Language/Type |
|---|---|
package.json, tsconfig.json, node_modules/ |
JavaScript/TypeScript |
go.mod, go.sum |
Go |
pyproject.toml, setup.py, setup.cfg, requirements.txt, Pipfile, .venv/, venv/ |
Python |
Cargo.toml, Cargo.lock |
Rust |
build.zig, build.zig.zon |
Zig |
Gemfile, *.gemspec, .ruby-version |
Ruby |
Package.swift, *.xcodeproj, *.xcworkspace |
Swift |
lakefile.toml, lakefile.lean, lean-toolchain, *.lean |
Lean |
*.sh, bin/*, scripts/* |
Shell |
*.zsh, #!/usr/bin/env zsh shebangs, .zshrc, .zshenv |
Zsh |
*.css, *.scss, *.less |
CSS/SCSS |
Dockerfile, *.dockerfile, docker-compose.yml |
Docker |
.github/workflows/ |
GitHub Actions |
*.toml (beyond Cargo.toml) |
TOML |
*.yaml, *.yml (many files) |
YAML |
*.md |
Markdown (always) |

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.

set-up-linters is a skill published in the GitHub repository cboone/agent-harness-plugins (2 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 5,838 once invoked, about $0.0002 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 2026-09-03.
