knowledge

knowledge is a skill for Claude Code from Kastalien-Research/thoughtbox. It costs 31 tokens per session (613 once invoked), scanned A, original, MIT.

A search workflow that looks across project memory, Thoughtbox knowledge, Git history, assumptions, development patterns, and saved session handoffs. It returns findings together with where they came from.

In plain words
What is it for?
Use it to investigate a topic across the project's knowledge stores, compare the freshness and relevance of findings, and present the results with their provenance.
Why use it?
It reduces the chance of missing relevant prior decisions or repeating work stored in another project record.

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

knowledge 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 1mo 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.

Search all knowledge stores for: $ARGUMENTS

Workflow

Phase 1: Parallel Search (Observe)

Execute all searches in parallel:

  1. MEMORY.md: Search the auto memory file at .Codex/projects/*/memory/MEMORY.md for the query terms using Grep
  2. Thoughtbox Knowledge Graph: Use ToolSearch to load thoughtbox_execute, then search entities and observations matching the query via tb.knowledge.listEntities({ name_pattern: "..." }) and tb.knowledge.queryGraph(...)
  3. Git History: Run git log --all --oneline --grep="$ARGUMENTS" -20 for commit history
  4. Assumption Registry: Search .assumptions/*.jsonl for matching assumption records using Grep
  5. DGM Patterns: Search .dgm/fitness.json for patterns matching the query using Grep
  6. Session Handoffs: Search .sessions/handoff-*.json for relevant context using Grep

Phase 2: Collate and Rank (Orient)

For each result found:

  1. Note the source store (provenance)
  2. Note the freshness (when was this last updated/verified)
  3. Note the relevance (how closely does it match the query)
  4. Check for cross-references (does this result reference other stores)

Phase 3: Present Results (Act)

Present results grouped by relevance, with provenance:

## Knowledge Query: "{query}"

### High Relevance
- [MEMORY.md] {finding} (line {N}, updated {date})
- [Thoughtbox] Entity: {name} — {observation} (created {date})

### Medium Relevance
- [Git] {commit-hash}: {message} ({date})

### Low Relevance
- [Assumptions] {assumption} (confidence: {N}%, last verified: {date})

### Cross-References
- Thoughtbox entity "{name}" relates to git commit {hash}

### Gaps
- No results found in: {store1}, {store2}
- Consider adding knowledge about "{query}" to {suggested_store}

Notes

  • If a store doesn't exist yet (e.g., .dgm/fitness.json not created), skip it silently
  • If Thoughtbox MCP tools aren't available, skip the knowledge graph search
  • Always show which stores were searched and which returned nothing — gaps are informative
  • If the query is broad, suggest more specific sub-queries

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.

knowledge is a skill published in the GitHub repository Kastalien-Research/thoughtbox (65 stars, last pushed 3mo ago), licensed MIT. It adds 31 tokens to every session and 613 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
