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 | $0.00062 | $0.02508 |
| Opus 5 | $0.00031 | $0.01254 |
| Sonnet 5 | $0.00012 | $0.00502 |
| Haiku 4.5 | $0.00006 | $0.00251 |
Grade A, and why
simplifying-code 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 4d 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.

Simplifying Code
Principles
| Principle | Rule |
|---|---|
| Preserve behavior | Output must do exactly what the input did -- no silent feature additions or removals. Specifically preserve: async/sync boundaries (do not convert sync to async or reverse), error propagation paths (do not alter strategy), logging/telemetry/guards/retries that encode operational intent, and domain-specific steps (do not collapse into generic helpers that hide intent). One carve-out: a shape that existed only in an earlier iteration of the current unshipped scope is not protected behavior. Verify it has no deployed, persisted, public, external, dependent-branch, or in-repo caller outside the resolved scope, and that every required caller update fits inside the edit boundary; otherwise keep the compatibility path. This narrow exemption is about shapes with provably zero consumers -- it never licenses removing a guard, which is governed by the evidence bar under AI Slop Removal |
| Explicit over clever | Prefer explicit variables over nested expressions. Readable beats compact |
| Simplicity over cleanliness | Prefer straightforward code over pattern-heavy "clean" code. Three similar lines beat a premature abstraction |
| Surgical changes | Touch only what needs simplifying. Match existing style, naming conventions, and formatting of the surrounding code |
| Surface assumptions | Before changing a block, identify what imports it, what it imports, and what tests cover it. Edit dependents in the same pass |
Changing an interface, exported name, persisted format, or path reaches past the import graph. Enumerate the producers, consumers, schemas, fixtures, generators, manifests, scripts and CI recipes, config references, and documents that carry the old identifier, and migrate them in the same pass. Close out by searching for the old identifier: zero hits, or one line accounting for each intentional remainder. Renames rot in the fixture holding the old key and the .env.example entry, neither of which any import graph contains. When the identifier is a public or exported API, Stop Conditions applies first -- confirm with the user, then enumerate; the sweep runs unprompted only for internal identifiers.
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.

simplifying-code is a skill published in the GitHub repository iliaal/ai-skills (40 stars, last pushed 5d ago), licensed MIT. It adds 62 tokens to every session and 2,508 once invoked, about $0.0003 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.
