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 | $0.00530 | $0.00530 |
| Opus 5 | $0.00265 | $0.00265 |
| Sonnet 5 | $0.00106 | $0.00106 |
| Haiku 4.5 | $0.00053 | $0.00053 |
Grade A, and why
cadkit-mcp 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 9d 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.

Project Conventions
- PRs target
main.mainis the mainline branch. - Tests:
pytest(all tests must pass). Coverage:pytest --cov(reported, not gated). - No enforced style/lint, type-checking, or coverage gate — only that tests pass.
Assembly Workflow (5-Step Methodology)
When building assemblies, follow this order:
- Ground a reference part — First instance is grounded by default. All positions are relative to this part.
- Get face IDs — Use
get_body_detailson the Part Studio. Face IDs are reusable across all instances of the same part. - Create mates in batches — Do 3-5 at a time, verify between batches with
get_assembly_features(all OK?) andget_assembly_positions(positions correct?). - Verify positions relative to the reference part — Always compute
instance_pos - reference_possince the reference may not be at origin. - Test motion mates — Create slider/revolute mates without limits first. Verify direction and animation before adding limits.
See knowledge_base/assembly_workflow_guide.md for the full guide and examples/cabinet_assembly.md for a worked example.
Critical Assembly Gotchas
- Instance order = direction: For slider/revolute/cylindrical mates, the first instance moves relative to the second. Swap the order to reverse the direction.
- Limits can break the solver: API-set limits trigger a full re-solve that may flip parts. Create mates without limits first, add limits in the Onshape UI.
- Fixed instances can't be moved:
transform_instanceandset_instance_positionfail on grounded parts (API 400 error). - MC offsets are in local coords: Flipping the Z-axis changes all axes (right-hand rule), which changes how X/Y offsets map to world space.

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.

cadkit-mcp CLAUDE.md is an instructions file published in the GitHub repository saltyeg/cadkit-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 530 tokens to every session, about $0.0027 per session on Opus 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 2026-08-31.
