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 5.1 | $0.00078 | $0.00768 |
| Opus 5.5 | $0.00031 | $0.00307 |
| Sonnet 5.5 | $0.00016 | $0.00154 |
| Haiku 4.5 | $0.00008 | $0.00077 |
Grade A, and why
skill-cutter 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 3d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Cutter
Reduce context cost and accidental activation while preserving the decisions that make the skill useful. Length is evidence, not a target.
Establish scope
- Audit requests authorize inspection and findings. Do not edit the target.
- An explicit request to implement findings, cut, trim or simplify authorizes local edits to the named skill scope, not publication or consumer installation.
- Read the complete
SKILL.md, available UI metadata and directly relevant resources. Preserve unrelated work and identify the user's requested outcome.
Classify before editing
Keep non-obvious domain constraints, fragile required sequences, exact file/tool contracts and action-specific authorization or data-integrity controls.
| Material | Treatment |
|---|---|
| Useful optional expert advice | Condense and mark non-blocking. |
| Generic knowledge or repeated policy | Delete. |
| Duplicate example or instruction | Keep the clearest useful instance. |
| Incident/project-specific rule in a generic skill | Move to its actual scope or delete. |
| Stale or unsupported claim | Verify with primary documentation, qualify or delete. |
| Useful detail for one variant | Link a selectively loaded reference. |
Do not move bulk merely to reduce the entrypoint's line count. Inspect callers before deleting scripts, assets or references; apparent non-use is insufficient.
Keep acceptance proportional
Blocking criteria come from the user outcome, higher-level invariants and risks created by the action. Distinguish:
- Invariant: explicit and narrow, such as preserving sample identity.
- Action-required: applies only to the named task, such as a file contract.
- Risk-triggered gate: names the risk and proportional proof.
- Recommendation/opportunity: advice or follow-up, not a prerequisite.
Flag unrelated coordination, optional infrastructure presented as mandatory, repeated approval despite established authorization, self-approval by a broken subsystem, and proof gathering that cannot change acceptance. More than one or two skill-added gates for a bounded task needs a concrete correctness, privacy, security, data-integrity or irreversible-action reason.
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.

skill-cutter is a skill published in the GitHub repository CHENyiru3/AI-Skills-Collections (2 stars, last pushed 3d ago), licensed MIT. It adds 78 tokens to every session and 768 once invoked, about $0.0003 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 2026-11-11.
