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 | $0.00014 | $0.00220 |
| Opus 5 | $0.00007 | $0.00110 |
| Sonnet 5 | $0.00003 | $0.00044 |
| Haiku 4.5 | $0.00001 | $0.00022 |
Grade A, and why
code-simplify 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 yesterday.
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.
This is a copy
91% identical to code-simplify — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Invoke the agent-harness:code-simplification skill.
Simplify recently changed code (or the specified scope) while preserving exact behavior:
- Read CLAUDE.md and study project conventions
- Identify the target code — recent changes unless a broader scope is specified
- Understand the code's purpose, callers, edge cases, and test coverage before touching it
- Scan for simplification opportunities:
- Deep nesting → guard clauses or extracted helpers
- Long functions → split by responsibility
- Nested ternaries → if/else or switch
- Generic names → descriptive names
- Duplicated logic → shared functions
- Dead code → remove after confirming
- Apply each simplification incrementally — run tests after each change
- Verify all tests pass, the build succeeds, and the diff is clean
If tests fail after a simplification, revert that change and reconsider. Use code-review-and-quality to review the result.
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.

code-simplify is a command published in the GitHub repository Ghosteken/agent-harness (2 stars, last pushed 15d ago), licensed MIT. It adds 14 tokens to every session and 220 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to code-simplify, differing in 2 lines, and is treated as a copy.

send
Send a message to a running agent session. Use this to correct or direct a live agent mid-stream without killing and respawning it.
dispatcher
Pick the next-best repo to work on across the portfolio — rank free repos, recommend one, claim its lease atomically, and route to the entry command.
journey-audit
Outside-in product audit as a deep session — 7 read-only roles check what the site promises against what the code does, what a user experiences, what arrives by mail, and what the data says is used. Writes a dossier; needs a per-repo journey-manifest.

Track session costs, understand token spend, and get optimization tips.
