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 | $0.01319 | $0.01319 |
| Opus 5.5 | $0.00528 | $0.00528 |
| Sonnet 5.5 | $0.00264 | $0.00264 |
| Haiku 4.5 | $0.00132 | $0.00132 |
Grade A, and why
claude-db 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 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.

CLAUDE.md — working on claude-db
Project instructions for Claude Code when developing this repository. claude-db is a Claude Code
plugin that turns Claude into a senior, multi-paradigm database expert: design a new schema,
audit an existing one on two independent axes, and plan safe migrations.
Architecture (skill-first, three layers)
Claude is the runtime; the Node/Python scripts are optional accelerators, never required.
- Directive skills —
skills/<name>/SKILL.mdbecomes/claude-db:<name>. The 10 commands:start,design,audit,explain,migrate,fix,next,score,seed,checklist. There is noengineorrecommendcommand — M0 engine selection is delivered bydesignandstart. - Orchestration —
skills/db-orchestratordetects the stack/paradigm (scripts/detect-stack.mjs), builds the shared schema snapshot (scripts/parse-schema.mjs,scripts/parse-orm-python.py), dispatches the read-only auditor subagents in parallel (multipleTaskcalls in one message), merges findings, runsscripts/score.mjs, and renders the report. - Module skills —
skills/db-*/SKILL.md, modules M0–M22. M0 (db-engine-selection) is an advisory recommendation and is not scored; M1–M22 are scored. Each module declares which axis it feeds:design,performance, orboth.
Agents (agents/<name>.md)
- Read-only auditors: tools
Read, Grep, Glob, Bash, WebFetch, modelsonnet. They emit a JSON array of findings conforming toschema/finding.schema.json. Read-only by tool allowlist. - Writer (
db-migration-writer): toolsRead, Edit, Write, Bash. Only reachable via/claude-db:fix.
The two-score model (never blend)
Two independent 0–100 scores with A–F bands: Design & Integrity (design) and
Performance & Scale (performance). A finding's expected_impact.axis routes it into the category
that owns its module in each axis independently. Severity gating caps a score at F on a severity:5
fail for that axis; needs_api and speculative findings never cap. The detected paradigm swaps
the category profile (scripts/score.mjs → PROFILES) so each axis still sums to 100. The full model
lives in references/scoring-model.md — conform to it, do not silently change weights.
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.

claude-db CLAUDE.md is an instructions file published in the GitHub repository Hainrixz/claude-db (21 stars, last pushed 2d ago), licensed MIT. It adds 1,319 tokens to every session, about $0.0053 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.
