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.

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 | $0.00064 | $0.01062 |
| Opus 5 | $0.00032 | $0.00531 |
| Sonnet 5 | $0.00013 | $0.00212 |
| Haiku 4.5 | $0.00006 | $0.00106 |
Grade A, and why
biome-complete 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 8d 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.

Biome Complete Toolchain
When to Apply
Use this skill when the request includes:
- "set up Biome"
- "configure biome.json"
- "migrate from ESLint" or "migrate from Prettier"
- "fix lint and format drift"
- "run Biome in CI"
When Not to Apply
Do not use this skill when the user asks for ESLint-only or Prettier-only solutions.
Principles
- Use one source of truth for linting and formatting.
- Prefer deterministic commands and verifiable output.
- Keep SKILL.md short; move deep details to
references/.
Deterministic Workflow
- Confirm scope: migration, config, lint, format, or CI.
- Initialize config if missing:
bunx @biomejs/biome init. - Run checks and capture results:
bunx @biomejs/biome check ..- Verify: Confirm diagnostics are printed. If command fails, check Node.js version (≥14) and file permissions.
- Apply safe autofixes:
bunx @biomejs/biome check . --write.- Verify: Re-run
biome check .and confirm reduced error count. If errors persist, review unsupported rules or migration conflicts inreferences/migration-eslint-prettier.md.
- Verify: Re-run
- Add targeted suppressions only when justified.
- Verify commands pass in local and CI contexts:
bunx @biomejs/biome check . --error-on-warnings.- Verify: Exit code 0 indicates success. If non-zero, review remaining diagnostics and address or document exceptions.
Error Recovery: If biome check fails after migration, isolate conflicting rules by temporarily disabling rule groups in biome.json linter section, then re-enable one group at a time to identify the source.
Quick Commands
Initialize
bunx @biomejs/biome init
Expected result: biome.json exists.
Check repository
bunx @biomejs/biome check .
Expected result: diagnostics printed with file paths.
Apply safe fixes
bunx @biomejs/biome check . --write
Expected result: fixable issues are rewritten.
Format files
bunx @biomejs/biome format . --write
What ships with it
24 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.
- 8d ago First seen · 136 lines · 64 tokens per session scan A b9535d1f7b21
biome-complete is a skill published in the GitHub repository pantheon-org/tekhne (10 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 1,062 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 2026-09-03.
