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 | $0.00123 | $0.01518 |
| Opus 5 | $0.00062 | $0.00759 |
| Sonnet 5 | $0.00025 | $0.00304 |
| Haiku 4.5 | $0.00012 | $0.00152 |
Grade A, and why
skill-tighten 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Tighten
Core responsibility: Fix language that causes agents to skip or underweight instructions. Not behavioral gaps — that is skill-review's job. Only phrasing: rationale prose, soft language, missing enforcement signals, redundant repetition.
Input: One or more of:
- A file path:
source/atoms/clean-code/SKILL.md - A skill name:
clean-code(resolves to the correct path automatically) - A tier:
atoms(tightens all skills in that tier) - No argument: tightens all skills across all tiers
Output: Edited files + a report per skill:
## skill-tighten — {skill-name}
Lines: {before} → {after}
Changes:
1. {what changed} — {one-line reason}
2. ...
Result: TIGHTENED ({N} changes) | CLEAN (no changes needed)
How to verify this skill did its job:
- Every cut section had zero commands — only rationale
- Every softened phrase was "consider / think about / you may want to / it is recommended"
- Every added STOP: was on a hard rule that previously had no enforcement signal
- No rule, gate, checklist item, or branching logic was removed
- Re-running after edits returns CLEAN
Step 1: Read the skill
Read the full SKILL.md. Also read all sibling files: references/defaults.md, references/methodology-detail.md, assets/template.md, or any file referenced by a Read instruction in the skill body.
Do not edit yet — complete the full audit first.
Step 2: Apply the tighten checklist
For each item, scan the entire file. Mark every instance found — do not stop at the first.
T1 — Non-actionable sections
Sections that explain why the skill exists, describe the problem, or narrate context without issuing a single command. Cut the entire section. Preserve the pointer to a referenced file if one exists.
Patterns that always qualify:
- Section titled "Core Principle", "Purpose", "Problem", "Background", "Why This Matters", "How It Is Used", "Integration with Other Skills"
- Opening paragraph before a numbered list that restates what the numbered list will do
- Closing paragraph after a gate that explains what happens if the gate were skipped
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-tighten is a skill published in the GitHub repository techygarg/lattice (185 stars, last pushed yesterday), licensed MIT. It adds 123 tokens to every session and 1,518 once invoked, about $0.0006 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.
