ccr AGENTS.md

ccr AGENTS.md is an instructions file for Codex, OpenCode from qbit-glitch/ccr. It costs 1,660 tokens per session, scanned A, original, Apache-2.0.

Project instructions for ccr, a Codex context reducer that provides persistent memory, reusable playbooks, a sandboxed read-evaluate-print loop, code search, and session logging through MCP. MCP is a way for an AI coding agent to call external tools.

In plain words
What is it for?
They are for using ccr's memory, playbook, repository-index, sandboxed REPL, and session-logging tools during development.
Why use it?
They give Codex a documented routine for preserving work between sessions, recording decisions, reusing successful patterns, and searching the project without loading every file at once.

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

ccr AGENTS.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 2d 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.

CCR — Codex Context Reducer

MCP server giving Codex persistent memory (GCC), self-evolving playbooks (ACE), and sandboxed REPL (RLM). No API keys needed — works with Codex Max.

How To Use CCR (MCP Tools)

Memory (GCC)

  • Session start: gcc_context(level=2) to load history
  • After progress: gcc_commit with what/why/files/next
  • Before compaction: Commit to preserve reasoning state
  • Alternatives: gcc_branch to isolate, gcc_merge when decided
  • Search: gcc_context(level=5, search_term="...")
  • Patterns: Include patterns_learned in commits; query with gcc_patterns

Playbook (ACE)

  • Review: ace_get_playbook then ace_update_counters (helpful/harmful tags)
  • Add insights: ace_apply_delta ADD
  • Maintain: ace_find_similar + MERGE duplicates, ace_prune harmful
  • Optional weight (0.0-1.0) for proportional credit on counters
  • Failure lessons: include failure_lesson dict when tagging harmful

REPL (RLM)

  • rlm_initrlm_execute (search_repo, get_file) → rlm_finalize

Index

  • index_search(query) — keyword/semantic/hybrid search
  • index_build — rebuild after code changes

Session Logger (SL)

  • After each response: session_log_turn(assistant_message="<your full response>") — logs this Q&A turn to .ccr/sessions.db
  • Review session: session_get_history() — last 20 turns of current session
  • Search past sessions: session_search(query="...") — full-text search all Q&A logs
  • Export for training: session_export(format="jsonl") — OpenAI fine-tuning format

Research & Experiment Tools (v6)

  • Log experiment: gcc_experiments(experiment_id=..., hypothesis_contains=..., metric_filter={...}) — query/filter experiment records stored in commits
  • Log decision: gcc_discuss(topic=..., hypothesis=..., decision=..., rationale=...) — persist reasoning behind design choices across sessions
  • List discussions: gcc_discussions(limit=20) — retrieve stored decision log
  • Semantic search: gcc_search(query=..., mode="hybrid") — keyword/semantic/hybrid search across all memory

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.
