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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00870 | $0.00870 |
| Opus 5.5 | $0.00348 | $0.00348 |
| Sonnet 5.5 | $0.00174 | $0.00174 |
| Haiku 4.5 | $0.00087 | $0.00087 |
Grade A, and why
post-cortex 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 16d 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.

Rules
- Search before answering — call
semantic_search(session → workspace → global) BEFORE answering any code/architecture question - Log after discovery — call
update_conversation_contextAFTER making decisions, fixing bugs, or changing code - Self-check — the Stop hook blocks a turn that changed project files (edits,
git commit) without a laterupdate_conversation_context

MCP Tools
Call directly — do NOT use subagents for simple search/log operations.
| Tool | When |
|---|---|
semantic_search |
Before answering code/arch questions. Scope: session / workspace / global. Returns structured payload (scores, content_id, content_type, snippet, timestamp) |
update_conversation_context |
After decisions, fixes, changes. Single or bulk. entities (≥1) and relations (≥1) are required (dangling/self-relations rejected). Content: typed keys (decision/rationale, problem/solution, concept/definition, question/answer, file/changes, requirement) or generic title/description |
get_structured_summary |
Session analysis and reviews. include values: decisions, insights, entities, questions, all. Also: decisions_limit, entities_limit, questions_limit, concepts_limit, min_confidence, compact |
query_conversation_context |
Flexible queries. query_type values: find_related_entities, get_entity_context, search_updates, entity_importance, entity_network, find_related_content (topic, max_results), key_decisions, key_insights (limit), session_statistics, structured_summary, decisions, open_questions, assemble_context, trace_relationships, get_most_important_entities, find_entities_by_type |
session |
Sessions: create, list, load (session_id), search (query), update_metadata (session_id + name/description; preserves created_at), delete (evicts cache + storage) |
manage_workspace |
Workspace CRUD: create, list, get, delete, add_session, remove_session; cards: get_card, update_card (content, expected_version; card: "user" for the user card) |
assemble_context |
Graph-aware retrieval (semantic + 1-hop traversal + impact analysis = reverse dependencies, "who depends on X"). Scope: session or workspace. Returns items (budget-packed), entity_context (with DirectMention / GraphNeighbor{via,relation}), impact, total_tokens, formatted_text (LLM-ready) |
manage_entity |
delete (entity_name; cascades typed edges), delete_update (entry_id; removes a single context row from hot/warm/incremental caches and persists) |
admin |
health, vectorize_session (session_id), vectorize_stats, create_checkpoint (session_id) |
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.
