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 | $0.00019 | $0.00482 |
| Opus 5.5 | $0.00008 | $0.00193 |
| Sonnet 5.5 | $0.00004 | $0.00096 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
preflight scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Wait for healthy: `curl -sf http://localhost:7475 > /dev/null` What it actually says
Pre-flight Check (Step 0)
Run all checks before starting any implementation work. Report pass/fail for each.
Checks
1. Git state
git branch --show-current
git status -s
git log --oneline -3
- Must be on a feature branch (feat/, fix/, chore/) — NOT on main, release, hotfix, or dev
- Working tree should be clean (untracked
.claude/files are OK)
2. Neo4j container
docker ps --format '{{.Names}} {{.Status}}' | grep codegraph-neo4j
- If not running:
cd codegraph && docker compose up -d - Wait for healthy:
curl -sf http://localhost:7475 > /dev/null
3. Python venv
.venv/bin/codegraph --help > /dev/null 2>&1
- If missing:
python3 -m venv .venv && .venv/bin/pip install -e ".[python,mcp,test]"
4. Test suite
.venv/bin/python -m pytest tests/ -q
- All tests must pass before starting new work
5. Graph state
.venv/bin/codegraph query "MATCH (n) RETURN count(n) AS nodes"
- If 0 nodes: suggest running
/graph-refresh

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.
- 2mo ago First seen · 60 lines · 19 tokens per session scan A f6f1a8244e02
preflight is a command published in the GitHub repository cognitx-leyton/codegraph (12 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 19 tokens to every session and 482 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

feedback
A design-stage security review for product requirement documents and other planning documents; a PRD is a document describing what a product should do.
va
A read-only security review of a codebase across eight architecture areas, with findings checked against file-and-line evidence.
compliance
A follow-up security check that verifies whether earlier findings were fixed and, depending on the selected mode, looks for new problems.
pentest
A read-only penetration-testing command for examining source code from an attacker’s perspective and producing proof-of-concept checks. Penetration testing is authorized security testing that tries to verify exploitable weaknesses.
run
A security-workflow coordinator that turns a natural-language request into a plan involving code review, verification, attack testing, or reporting.
verify
An independent recheck of a security assessment report that derives conclusions from its own evidence instead of accepting the original findings.
