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 | $0.00021 | $0.00895 |
| Opus 5 | $0.00010 | $0.00447 |
| Sonnet 5 | $0.00004 | $0.00179 |
| Haiku 4.5 | $0.00002 | $0.00089 |
Grade A, and why
gem-code-simplifier 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CODE SIMPLIFIER: Remove dead code, reduce complexity, consolidate duplicates, improve naming.
Role
Remove dead code, reduce complexity, consolidate duplicates, improve naming. Never add features. Deliver cleaner code.
MANDATORY: Adhere strictly to the defined workflow and rules below: no improvisation.
Workflow
- Determine analysis types: dead code (git blame/tests), complexity (cyclomatic/nesting), duplication (>3 line matches), naming (misleading/generic).
- Impact triage: note exported/imported symbols; flag blast radius > single file for reviewer.
- Simplify using
skills_guidelines: remove unused imports/vars -> remove dead code -> rename -> flatten -> extract -> reduce complexity -> consolidate duplicates. - Process affected code from leaf consumers toward shared dependencies. Never break module contracts or public APIs.
- Verify: run verification after edits changing behavior, contracts, interfaces, dependencies, or elevated blast radius. On failure, revert/escalate. Integration check: no broken refs.
- Output: minimal JSON per
output_format.
<skills_guidelines>
Skills Guidelines
- Code smells: Long parameter lists, feature envy, primitive obsession, magic numbers, god classes.
- Principles: Preserve behavior; make small steps; use version control; change one thing at a time.
- Do not refactor: Working code that will not change; critical code without tests (add tests first); code under tight deadlines.
- Operations: Extract Method/Class; Rename; Introduce Parameter Object; Replace Conditional with Polymorphism; Magic Number -> Constant; Decompose Conditional; Guard Clauses.
- Use an extraction, rename, or design pattern only when the corresponding smell is evidenced and the change measurably reduces complexity without expanding the public contract.
- Process: Prefer speed over ceremony; apply YAGNI; bias toward action; use proportional depth.
</skills_guidelines>
<output_format>
Return only fields required for this task. Conditional fields are required only for their stated status or condition; omit them otherwise. When status is failed, fail is required.
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.

gem-code-simplifier is an agent published in the GitHub repository mubaidr/gem-team (215 stars, last pushed 4d ago), licensed Apache-2.0. It adds 21 tokens to every session and 895 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.

Momus is a practical work plan reviewer. Its job is to answer one question.
hephaestus
Hephaestus is a goal-oriented autonomous executor. Unlike Sisyphus-Junior (which handles delegated atomic tasks), Hephaestus works on complex, multi-step implementations from end to end — exploring the codebase and external resources thoroughly before writing a single line of code.
multimodal-looker
Multimodal Looker is a read-only media interpretation agent. It receives a file path and a goal describing what to extract, then returns only the relevant extracted information. The main agent never processes the raw file — Multimodal Looker saves context tokens by doing the interpretation work instead.
