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 | $0.00043 | $0.00493 |
| Opus 5.5 | $0.00017 | $0.00197 |
| Sonnet 5.5 | $0.00009 | $0.00099 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
cortex-graph-search 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 2mo 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
Cortex graph and search
Knowledge graph
- Storage:
cortex/graph/store.py— NetworkXDiGraph, persisted to{vault}/.cortex/graph.json. - Models:
cortex/vault/models.py—NodeType,EdgeType,GraphNode,GraphEdge. - Rebuild:
cortex/graph/builder.pyscans vault markdown and wikilinks.
Node types
note, tag, agent, session, daily, feedback (from path prefix or frontmatter type).
Edge types
links_to, authored_by, contradicts, derived_from, supersedes, memory_of, tagged_with.
API surface
- REST:
POST/GET/DELETE /api/v1/links,GET /api/v1/graph/stats - MCP:
vault_link,vault_context(expands neighbors from search hits)
QMD search
- Module:
cortex/search/qmd.py— wraps QMD CLI for keyword, semantic, and hybrid modes. - Debounce: After
vault_write,QmdDebounceschedules index refresh (cortex/search/debounce.py). - Modes:
keyword,semantic,hybrid(default hybrid in many call sites).
vault_context flow
- Run search with
query - Take top notes
- Expand graph neighbors up to
max_depth - Return combined context for agents
VaultWatcher sync
cortex/vault/watcher.py updates graph on file changes so disk edits stay consistent without full rebuild.
Debugging
- Empty search: check QMD index / vault path /
CORTEX_VAULT_PATH - Missing edges: run graph rebuild or trigger watcher; verify wikilink targets exist under allowed folders
- Stats:
GET /api/v1/graph/stats

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.

cortex-graph-search is a skill published in the GitHub repository synpulse8-opensource/pulse8-ai-cortex-knowledge-vault (15 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 493 once invoked, about $0.0002 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.
