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 | $0.09863 | $0.09863 |
| Opus 5.5 | $0.03945 | $0.03945 |
| Sonnet 5.5 | $0.01973 | $0.01973 |
| Haiku 4.5 | $0.00986 | $0.00986 |
Grade A, and why
openccu-loom 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 729 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — AI Assistant Guide for OpenCCU-Loom
The entry point for AI assistants working on OpenCCU-Loom. It is
deliberately short: it states each rule once and names the guard or the
document that carries the rest. Design intent lives in
SPECIFICATION.md; implementation detail lives in the
code. When in doubt about intent, read the spec; about implementation,
read the code.
Rules that apply only inside one subtree live in that subtree, so you pay for them only when you work there:
| File | Covers |
|---|---|
go-fabric CLAUDE.md |
the matter.js gold-standard workflow, schema regeneration — the Matter stack is its own module now |
assets/ui/CLAUDE.md |
SPA operating concept, i18n + theme duty, Playwright suite |
tests/CLAUDE.md |
the test pillars, test naming, the snapshot-parity pipeline |
internal/model/custom/CLAUDE.md |
adding a device profile |
Two long-form companions carry the reasoning behind the compressed rules
below — read them when a guard fires and you want to know what it protects:
notes/contributor/engineering-rules.md
and
notes/contributor/subagent-delegation.md.
Orientation
If you are a fresh agent starting work on this repo:
- Read
SPECIFICATION.mdend-to-end (~900 lines): goals, constraints, resolved decisions, risk register. Its preamble points at the authoritative source for everything else. - Read
docs/adr/0001-license-mit.mdanddocs/adr/0002-multi-ccu-first-class.md— the two most consequential decisions. - "aiohomematic" is shorthand for the whole Python reference family; see References.
CHANGELOG.mdis the authoritative release history. The build version isinternal/build/version.go; the RESTAPIVersionininternal/north/rest/handlers/info.gois bumped independently. Counts of handlers / commands / profiles drift every release — readassets/openapi.yaml,assets/wsapi.jsonand the registry instead of trusting a number in prose.
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.
