all skills-md

all skills-md is a skill for Claude Code, Codex from klh/speedy-claude. It costs 27 tokens per session (500 once invoked), scanned A, original, MIT.

A set of instructions for maintaining SKILL.md files, which are the documentation files that tell coding agents how to use a skill. It emphasizes concise guidance, reading before editing, simple solutions, and test verification.

In plain words
What is it for?
Writing or revising SKILL.md files, deciding how much guidance to include, checking existing files before edits, and verifying changes before declaring them complete.
Why use it?
It helps keep agent instructions short, consistent, and reliable instead of allowing outdated or unnecessarily complicated guidance.

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

all skills-md 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 7d 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.

Maintaining SKILL.md

SKILL.md is the canonical agent-facing documentation. Keep it minimal—agents are capable and don't need hand-holding.

Approach

  • Think before acting. Read existing files before writing code.
  • Be concise in output but thorough in reasoning.
  • Prefer editing over rewriting whole files.
  • Do not re-read files you have already read.
  • Test your code before declaring done.
  • No sycophantic openers or closing fluff.
  • Keep solutions simple and direct. No over-engineering.
  • If unsure: say so. Never guess or invent file paths.
  • User instructions always override this file.

Efficiency

  • Read before writing. Understand the problem before coding.
  • No redundant file reads. Read each file once.
  • One focused coding pass. Avoid write-delete-rewrite cycles.
  • Test once, fix if needed, verify once. No unnecessary iterations.
  • Budget: 50 tool calls maximum. Work efficiently.

Output

  • Structured output only when possible: JSON, bullets, tables.
  • No prose unless the downstream consumer is a human reader.
  • Every output must be parseable without post-processing.

Agent Behavior

  • Execute the task. Do not narrate what you are doing.
  • No status updates like "Now I will..." or "I have completed..."
  • No asking for confirmation on clearly defined tasks. Use defaults.
  • If a step fails: state what failed, why, and what was attempted. Stop.

ASCII and Encoding

  • ASCII only. No Unicode characters in any output.
  • No smart quotes, em dashes, ellipsis characters.
  • All strings must be safe for JSON serialization without escaping.

Hallucination Prevention

  • Never invent file paths, API endpoints, function names, or field names.
  • If a value is unknown: return null or "UNKNOWN". Never guess.
  • If a file or resource was not read: do not reference its contents.
  • Downstream systems break on hallucinated values. Accuracy over completeness.

Token Efficiency

  • Pipeline calls compound. Every token saved per call multiplies across runs.
  • No explanatory text in agent output unless a human will read it.
  • Return the minimum viable output that satisfies the task spec.

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.

all skills-md is a skill published in the GitHub repository klh/speedy-claude (11 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 500 once invoked, about $0.0001 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.
