claude-md-creator

claude-md-creator is a skill for Claude Code from brunob54/superpowers-orchestrator. It costs 88 tokens per session (1,189 once invoked), scanned A, original, MIT.

A workflow for creating or updating CLAUDE.md and AGENTS.md files, which give coding agents project-specific instructions and commands.

In plain words
What is it for?
Use it when setting up a project, running an initialization command, or creating or updating agent guidance with build, test, and lint instructions.
Why use it?
It keeps those instruction files short and focused, reducing repeated information that can distract an agent or increase its work.

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

claude-md-creator 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 12d 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.

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE / AGENTS Context File Creator

Creates repository-level context files (CLAUDE.md, AGENTS.md) that give coding agents the minimum guidance needed to work correctly in a repo.

Core principle: Only include what the agent cannot easily discover itself.

Empirical research (Gloaguen et al., 2026 — "Evaluating AGENTS.md") shows that LLM-generated context files decrease agent performance by 3% and increase cost by 20-23% when they contain redundant or overly broad content. Human-written, minimal context files improve performance by ~4%. The difference comes down to signal density — every unnecessary line adds cognitive load without helping the agent solve tasks.

Trigger Conditions

Invoke this skill when any of the following occur:

  • The /init command is run
  • The user asks to create, write, or update a CLAUDE.md or AGENTS.md
  • The user mentions "agent context", "initialize project", "set up Claude Code"
  • A repo is missing a CLAUDE.md and the user begins a new project setup
  • During brainstorming or writing-plans when the repo lacks a context file

What to Include (highest to lowest priority)

1. Build, test, and lint commands (highest impact)

Explicit tool and command mentions are the single most effective instruction type — agents use mentioned tools 1.6x-2.5x more often. Spell out exact commands:

npm run test -- --watch
uv run pytest tests/ -x
make lint && make typecheck

2. Non-obvious environment setup

Env vars, required services, secrets handling, database setup — things the agent would get wrong without being told.

3. Critical constraints (things that cause wrong behavior if violated)

Focus narrowly on constraints where violating them breaks something:

  • "Never edit files in generated/ — they're overwritten by codegen"
  • "Always run migrations through the ORM, never raw SQL"
  • "The legacy/ module uses CommonJS — no ES imports"

4. Repo-specific patterns and anti-patterns

Only patterns unique to this project that differ from standard practice. If it's what any experienced developer would do by default, leave it out.
