mcp-freestyle: Instructions file for Claude Code

CLAUDE.md

mcp-freestyle CLAUDE.md is an instructions file for Claude Code from lozit/mcp-freestyle. It costs 3,512 tokens per session, scanned A, original, MIT.

A CLAUDE.md instruction file for the mcp-freestyle project, intended for Claude Code, an AI coding tool. It tells the tool which project documents to read first and when to record lessons or progress.

In plain words
What is it for?
Directing Claude Code to read project plans, lessons, and vision documents, then update project notes at important work checkpoints.
Why use it?
It gives coding sessions a consistent starting point and preserves project knowledge after milestones, mistakes, or before releases.

Instructions file for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is lozit/mcp-freestyle's own configuration. It tells Claude Code how to work on mcp-freestyle 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 mcp-freestyle 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

mcp-freestyle CLAUDE.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 6d 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — mcp-freestyle

This file is mutable and iterative. Update it after every Claude mistake or newly discovered convention. Target: < 200 lines.

Relationship with the global CLAUDE.md: this file is loaded in addition to the global (~/.claude/CLAUDE.md + enterprise policy) — on conflict the global/enterprise rule wins. Omitted here (your global already covers them): none.

Session start — read first, in order

  1. PLAN.md — where the project stands now (if present)
  2. docs/LEARNINGS.md — rules learned from past corrections (apply them!)
  3. docs/VISION.md — goal, scope, non-goals (if present)
  4. The artifacts of whatever is in progress per PLAN.md

Capture at checkpoints (don't wait to be asked)

The agent can't perceive "end of session" — so capture at the work boundaries it can see, and propose it proactively there without waiting for the user:

  • Before a git push, a tag, or a release — the highest-value, most reliable moment: pause and capture before shipping.
  • When a PLAN.md milestone is completed, or after a substantial chunk of work.

You can also trigger it yourself any time with /groundrules:checkpoint.

At that moment, three questions, each routed to where it belongs:

  1. Decided anything structural? → /groundrules:add-adr (docs/decisions/)
  2. Learned something that changes how to work here (incl. a blocker that cost 30+ min, with its fix)? → /groundrules:learn (docs/LEARNINGS.md)
  3. Caught the agent repeating a mistake, hallucinating, or drifting? → note it in docs/AGENT-EVALS.md (if present) and add the guard here or in .claude/rules/

Capture beats memory: if it's not written to the repo, it's gone next session.

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.
