graph-hygiene

graph-hygiene is a skill for Claude Code, Codex from dgraziosi/foundation. It costs 39 tokens per session (426 once invoked), scanned A, original, MIT.

A weekly, report-only review of the graph, meaning the connected knowledge stored in the vault. It looks for duplicate records, records with no connections, and conflicting record types.

In plain words
What is it for?
Use it to report duplicate titles, isolated records, and types that do not fit the vault’s structure.
Why use it?
It shows where the stored knowledge may be messy without merging, deleting, or changing anything.

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

graph-hygiene 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 yesterday.

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

Graph hygiene

You are running graph hygiene. The user can run this, or attach it to Vault Keeper.

Read docs/GRAPH_HYGIENE.md and follow it. Call bootstrap if you need the current tools.

The user is the human who runs this vault on this machine. The graph is the knowledge in this vault. Do not call the graph “the Vault.”

Schedule and voice

Weekly, local time. If there is nothing to report, stay quiet. Ping the user only when you found duplicates, isolates, or type soup.

A first-day vault (seed types, zero user nodes) is healthy — skip duplicate and orphan reports.

User config (fill in)

Checks (report only)

  1. Duplicate titles among live nodes. Report id, type, title. Do not merge.
  2. Live nodes with zero edges. Report them; do not delete. Skip if the graph has no user nodes.
  3. Type soup: inspect_ontology / bootstrap types. Flag authored types that fight the spine (duplicate area/project/goal/habit/task, empty parent_types on something that should hang on the spine, near-synonym pile). System seeds are not soup. Do not manage_type on this run.

Prefer MCP (bootstrap, inspect_ontology, get, search, list_activity). There is no list_nodes tool. Page search by type until next is omitted. Do not list the graph around MCP.

This pass is the weekly graph report. Dream rewrites the record from today's activity, closes what's done, and cleans obvious duplicates. Vault health and product updates have their own schedules.

This routine reports. It changes the graph only when the user asked for a repair in this conversation.

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.
