cgraph-enrich

A workflow for adding documentation and other prose to cgraph's code graph. A code graph maps relationships in source code; this workflow adds meaning from written documents.

In plain words
What is it for?
Use it to plan document chunks, read them, write semantic fragments, and add those fragments to cgraph until all pending inputs are processed.
Why use it?
It makes design notes and documentation searchable alongside code while skipping unchanged files through content checks.

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

cgraph-enrich 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.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cgraph-enrich

cgraph extracts code structure deterministically, but documentation, design notes, and other prose only enter the graph as host-authored semantic fragments. This skill is the loop that produces them. The native tool owns chunk planning, fragment validation, content-hash caching, and graph mutation; you (the model) own reading each chunk and authoring the fragment. No model logic lives in the binary.

The loop

Run from the project root. Repeat until the plan reports 0 input(s).

  1. Plancgraph enrich-plan --root . --out cgraph-out Writes cgraph-out/semantic-drop/plan.json, listing only uncached or stale chunks. Each chunk has inputs[].path and a fragment field — the exact filename to drop. Already-enriched files are skipped via the content-hash cache. Fragment names are offset past the fragments already in the drop dir, so the directory accumulates across passes and a new pass never overwrites an earlier one — always read the fresh plan and use the names it gives.

  2. Author — for each chunk in plan.json:

    • Read every file in inputs[].path.
    • Author ONE fragment capturing the chunk's concepts and how they relate to each other and to the code (see Fragment shape below).
    • Write it atomically to cgraph-out/semantic-drop/<chunk.fragment> — the filename from the chunk's fragment field, never a name you pick yourself. Write a temp file in that directory, then rename it into place. Do not reuse or overwrite an existing fragment file.
  3. Merge — one of:

    • Batch: cgraph enrich-ingest --root . --out cgraph-out validates every dropped fragment, merges the valid ones, updates the cache, and re-exports.
    • Live: if a daemon is running (graph_status), dropping the file is enough — the watcher validates and merges it into the live snapshot within ~200ms.
  4. Verify & repeat — re-run enrich-plan. Enriched files are now cache hits and drop out. graph_status shows enrichment_pending falling and node_count rising. Loop until pending is 0. Malformed fragments are rejected and leave the graph unchanged (enrichment_state: failed); fix and re-drop the same chunk_<index>.json.

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.

cgraph-enrich is a skill published in the GitHub repository Nxtsoft/CGraph (2 stars, last pushed 5d ago), licensed MIT. It adds 128 tokens to every session and 1,435 once invoked, about $0.0006 per session on Opus 5. 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.
