cf-index

A command that indexes a codebase into ContextForge, a knowledge graph that maps code structure and relationships.

In plain words
What is it for?
Use it before implementing a feature to index the repository, check indexing, inspect the architecture, and report what was discovered.
Why use it?
It gives the implementation workflow an architectural map before changes are made, so the agent can find related code and estimate the effect of edits.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

cf-index 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 3d 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.

What it actually says

/speckit.cf-index

Index the codebase into the ContextForge knowledge graph before implementing.

Steps

  1. Call cf_stats() — confirm ContextForge is connected
  2. Call cbm_index_repository(repo_path=".") — build the knowledge graph
  3. Call cbm_get_indexing_status() — confirm completion
  4. Call cbm_get_architecture() — show compressed architecture overview
  5. Report: files indexed, modules detected, token savings, ready for /speckit.cf-implement

Notes

  • Re-run after significant refactoring
  • Use cbm_* tools instead of grep/Read for ALL structural queries after indexing
Changes

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.

cf-index is a command published in the GitHub repository capatinore/contextforge-mcp (4 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 142 tokens. 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 2026-08-31.
