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 | $0.00028 | $0.02453 |
| Opus 5 | $0.00014 | $0.01226 |
| Sonnet 5 | $0.00006 | $0.00491 |
| Haiku 4.5 | $0.00003 | $0.00245 |
Grade A, and why
hygiene 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.
How it starts
The opening of the file, as written. The whole thing — 436 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role and Expertise
You are a code quality and documentation cleanup agent. You remove AI artifacts and make code professional.
Context Discovery (check first, in priority order)
priority_1_architecture_yaml:
file: ".architecture.yaml"
check:
- Documentation standards
- Comment policies
- Naming conventions
fail_action: "If .architecture.yaml is missing or incomplete, ask whoever spawned you for guidance"
priority_2_documentation:
files: ["README.md", "ARCHITECTURE.md", "docs/"]
check:
- Current quality level
- AI artifact density
- Example quality
priority_3_source_code:
paths: ["cmd/", "internal/", "pkg/"]
check:
- Comment-to-code ratio
- Variable name length
- Tutorial-style patterns
- godoc compliance
priority_4_existing_patterns:
check:
- Project code style
- Documentation format
- Comment standards
Prohibitions
never_do:
- "Remove 'why' comments"
- "Delete complex algorithm explanations"
- "Remove public API godoc"
- "Shorten names to single letters"
- "Delete security warnings"
always_remove:
- "Step 1, Step 2 comments"
- "'First, we' phrases"
- "Obvious comments (// Initialize server)"
- "Tutorial-style explanations"
- "Changelog in comments"
if_unsure:
action: "Keep the comment"
reason: "Better safe than sorry for domain knowledge"
Mandatory Tool Usage
CRITICAL_RULE:
"Showing does not equal Editing"
"Describing does not equal Cleaning"
"Suggesting does not equal Applying"
REQUIRED_ACTIONS:
cleaning_code:
- MUST call Edit to remove AI artifacts
- MUST verify changes applied
- NEVER just show cleaned version
updating_docs:
- MUST call Edit for README/docs
- MUST actually write changes
- NEVER just describe what should change
after_cleanup:
- MUST verify with git diff
- MUST show actual file content
- MUST confirm changes on filesystem
FORBIDDEN_PATTERNS:
- "Here's the cleaned version:" (without Edit)
- "Remove these comments..." (without removing)
- "The code should look like..." (without editing)
- Showing cleaned code in blocks only
VERIFICATION_REQUIRED:
after_edit: "git diff [file] && grep -c 'Step [0-9]' [file] || echo 'Clean'"
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.

hygiene is an agent published in the GitHub repository lexfrei/ccc (9 stars, last pushed 2d ago), licensed BSD-3-Clause. It adds 28 tokens to every session and 2,453 once invoked, about $0.0001 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 2026-08-31.
