.agents/skills/cheatsheet/SKILL.md

cheatsheet is a skill for Claude Code from VGrss/Acumen. It costs 20 tokens per session (772 once invoked), scanned A, original, Apache-2.0.

A command that prints a compact list of all available Acumen skills, grouped by what kind of product work they support.

In plain words
What is it for?
Use it to discover skills for context gathering, audits, idea generation, creating work, communication, and other Acumen tasks.
Why use it?
It gives you one current reference for available commands instead of requiring you to remember skill names or search through the project.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents).

This is VGrss/Acumen's own configuration. It tells Claude Code how to work on Acumen itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Acumen configures →

Token cost

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.

Security

Grade A, and why

cheatsheet 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 2mo 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Print a compact cheatsheet of every Acumen skill so the user can see what's available at a glance.

Mindset

You are a helpful reference card. No analysis, no opinions — just a clean, scannable list of every command the user can run, what it does, and when to reach for it. The list must reflect the skills that actually exist right now, not a memorized set.

Build the list (do this every time — never print from memory)

  1. Enumerate skills. List the skill directories: ls -1 source/skills/. Each directory is one skill with a source/skills/{name}/SKILL.md.
  2. Read each skill's frontmatter. For every skill, read its SKILL.md YAML frontmatter and capture name, description, and whether user-invocable: true is present.
    • Skills without user-invocable: true are core skills invoked by other skills (e.g. product-thinking). Omit them from the cheatsheet — they are not commands the user runs directly.
  3. Group by layer. Read the "Skill layers" section of CLAUDE.md and use it as the grouping and ordering source. Current layers: Context, Audit, Ideate, Craft, Communicate, Meta.
    • Assign each user-invocable skill to its layer per CLAUDE.md.
    • If a user-invocable skill is not listed in any layer in CLAUDE.md, place it under an OTHER group at the end rather than dropping it — a skill must never be silently omitted. (If OTHER is non-empty, it's a signal that CLAUDE.md's Skill layers section needs updating.)

Output

Render the cheatsheet as a boxed ASCII card using the data you just gathered. Use this structure — one section per layer (in CLAUDE.md order), each skill as /{name} padded with dots to a short one-line summary derived from its description. Do not add commentary before or after the box.
