culi: Instructions file for Claude Code

CLAUDE.md

culi CLAUDE.md is an instructions file for Claude Code from hung12ct/culi. It costs 1,208 tokens per session, scanned A, original, MIT.

Project instructions for Culi, a tool that selects relevant notes and guidance for coding-agent requests. It stores these notes as small cards and can learn from conversations and Git history.

In plain words
What is it for?
Building, running, and maintaining Culi, including its Go code, knowledge store, search index, hooks, and MCP server.
Why use it?
It reduces repeated project instructions and avoids loading unrelated guidance into every request.

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

This is hung12ct/culi's own configuration. It tells Claude Code how to work on culi 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 culi 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

culi 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 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.

CLAUDE.md — Culi

Culi (cà phê culi — the single dense peaberry bean; sibling of Phin) is a context orchestrator for Claude Code and OpenAI Codex: one canonical knowledge store of small "cards" (rules / skills / lessons / styles / patterns), token-budgeted context injection via harness hooks, on-demand depth via an MCP server, and background learning from transcripts + git history. Built on gopheragent. Pure Go, one binary, no CGO.

Product goal: kill per-repo CLAUDE.md/skill duplication and inject only the most relevant context per prompt — small, dense, concentrated. Like the bean.

Full approved design: ~/.claude/plans/right-now-for-every-zazzy-graham.md (retrieval funnel, schemas, learning pipelines, phased roadmap).

Architecture

  • One binary culi, subcommand dispatch in cmd/culi/main.go (stdlib flag, no cobra).
  • Files are truth: ~/.culi/knowledge/ (git-init'd markdown cards with YAML frontmatter) is the source of truth for cards; ~/.culi/index.db provides SQLite FTS5 BM25 + embeddings and also holds runtime activity. Card-search tables are rebuildable, while explicit forward migrations preserve injections, card stats, session state, and metadata across schema changes.
  • Push: culi hook <event> — normalized Claude/Codex UserPromptSubmit, SessionStart, Stop, and SessionEnd adapters.
  • Pull: culi mcp — stdio MCP server (modelcontextprotocol/go-sdk): search_context, expand_card, save_lesson.
  • Learning (internal/learn/): Claude/Codex transcript mining, style synthesis, branch→CLAUDE.md/AGENTS.md generation, cross-branch patterns — OpenAI/Anthropic API, Codex/Claude terminal, or Ollama backends behind hard daily caps. Codex lifecycle workers also perform a throttled read-only rollout scan as a missing-transcript_path fallback; scanner telemetry is content-free and surfaced by culi doctor.
  • Embeddings: local Ollama (nomic-embed-text) behind gopheragent's tools.Embedder; every path degrades gracefully to BM25-only when Ollama is down.
  • Review console: culi serve — local net/http server (internal/serve/) serving an embedded vanilla-JS dashboard (embed.FS, no build step): overview, candidate review, knowledge base + search, injection activity (per-event card breakdown + repo attribution), settings/repos manager. Off the hot path, so stdlib-only (C2) does not apply. Read-mostly; card actions (down/retire/ remove/edit) and config/repos writes are git-backed and respect C4 (retire = reversible status flip; hand-authored cards never round-trip through Render).

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.
