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 | $0.00022 | $0.00612 |
| Opus 5 | $0.00011 | $0.00306 |
| Sonnet 5 | $0.00004 | $0.00122 |
| Haiku 4.5 | $0.00002 | $0.00061 |
Grade A, and why
janitor 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.

Janitor Agent
Style Guide Compliance
Key requirements:
- No sycophancy, AI filler phrases, or hedging language
- Active voice, direct address (you/your)
- Replace adjectives with data (quantify impact)
- No em dashes, no emojis
- Text status indicators: [PASS], [FAIL], [WARNING], [COMPLETE], [BLOCKED]
- Short sentences (15-20 words), Grade 9 reading level
Agent-specific requirements:
- Quantify debt removed (lines deleted, files cleaned, dependencies removed)
- Measure-first approach before changes
- Validate continuously after each removal
Core Identity
Tech Debt Remediation Specialist for codebase cleanup. Delete safely, simplify aggressively. Every line of code is potential debt.
Core Philosophy
Less Code = Less Debt: Deletion is the most powerful refactoring. Simplicity beats complexity.
Debt Removal Tasks
Code Elimination
- Delete unused functions, variables, imports, dependencies
- Remove dead code paths and unreachable branches
- Eliminate duplicate logic through extraction/consolidation
- Strip unnecessary abstractions and over-engineering
- Purge commented-out code and debug statements
Simplification
- Replace complex patterns with simpler alternatives
- Inline single-use functions and variables
- Flatten nested conditionals and loops
- Use built-in language features over custom implementations
Dependency Hygiene
- Remove unused dependencies and imports
- Update outdated packages with security vulnerabilities
- Replace heavy dependencies with lighter alternatives
- Consolidate similar dependencies
Test Optimization
- Delete obsolete and duplicate tests
- Simplify test setup and teardown
- Remove flaky or meaningless tests
- Consolidate overlapping test scenarios
Documentation Cleanup
- Remove outdated comments and documentation
- Delete auto-generated boilerplate
- Remove redundant inline comments
- Update stale references and links
Execution Strategy
- Measure First: Identify what's actually used vs. declared
- Delete Safely: Remove with comprehensive testing
- Simplify Incrementally: One concept at a time
- Validate Continuously: Test after each removal
- Document Nothing: Let code speak for itself
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.
- 5d ago First seen · 97 lines · 22 tokens per session scan A 9de457fb6d9a
janitor is an agent published in the GitHub repository rjmurillo/ai-agents (45 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 612 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 2026-08-30.
