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 | $0.00031 | $0.01442 |
| Opus 5.5 | $0.00012 | $0.00577 |
| Sonnet 5.5 | $0.00006 | $0.00288 |
| Haiku 4.5 | $0.00003 | $0.00144 |
Grade A, and why
code-simplification 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 1mo 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code simplification
Two modes share one authority: reversible local edits to a named target, no new public surface, behavior preserved. Measured mode proves reduction with the test suite; clarity mode proves preservation by reasoning over the recorded behavior contract.
Contract
| Field | Bound contract |
|---|---|
| Trigger | User asks to simplify, clean, refactor, or improve the readability of code, or review flags bloat beyond the current diff. |
| Authority | Reversible local: writes only the named target (may refactor, extract, inline, and collapse conditionals; may not add new public surface or edit files outside the target); rollback is version control or undo. No remote mutation. |
| Side effect | Refactoring edits to the named target only; no new public surface. |
| Done | Mode-specific done predicate holds (see each mode); behavior is preserved by tests (measured) or by recorded-contract reasoning (clarity). |
Inputs
- Target (required): the file, module, function, or range to simplify. Named by the user.
- Test command (required for measured mode): the command that runs the test suite proving behavior preservation.
- Bloat signal (optional, measured mode): a review-flagged duplication hotspot or branch-complexity concern to prioritize. If absent, measure duplication and branch complexity on the target.
- Constraints (optional, clarity mode): behavior that must stay identical (public signatures, outputs, side effects, ordering). Infer these from the code when omitted.
Mode selection
| User says | Mode | Gate |
|---|---|---|
| simplify, clean, debloat, reduce duplication or complexity, review flagged bloat | measured | Test suite green and bloat signal lower than baseline |
| simplify for readability, clean up, refactor for clarity, make this clearer | clarity | Recorded behavior contract unchanged after each edit |
When the user names a test command or a bloat signal, use measured mode. When the user names only a readability goal and no test command, use clarity mode. When both are supplied, use measured mode and prefer clarity-preserving candidates.
What ships with it
1 file 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.

code-simplification is a skill published in the GitHub repository OutlineDriven/outline-driven-development (53 stars, last pushed 22d ago), licensed Apache-2.0. It adds 31 tokens to every session and 1,442 once invoked, about $0.0001 per session on Opus 5.5. 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.
