What it costs to keep this loaded
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 | $0.00085 | $0.01801 |
| Opus 5 | $0.00043 | $0.00901 |
| Sonnet 5 | $0.00017 | $0.00360 |
| Haiku 4.5 | $0.00009 | $0.00180 |
Grade A, and why
catia-v5-mcp-maintainer 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 13d 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.

CATIA V5 MCP Maintainer
Use this skill when changing the target MCP server itself. Production support is a contract between schema, implementation, runtime behavior, diagnostics, recovery, and tests. Tool count alone is not a reliability metric.
Mandatory engineering rules
- Inspect repository-local schema and implementation before changing or documenting a tool.
- Keep public schemas truthful: every advertised input must be consumed with defined semantics or removed/deprecated.
- Serialize CATIA COM access through a dedicated STA execution boundary; do not let arbitrary MCP request threads use shared COM objects directly.
- Return structured results with deterministic success/failure classification. Human-readable text is a secondary representation, not the primary protocol.
- Separate CATIA update success from intended geometry effect.
- Give material-changing operations measurable postconditions and explicit no-effect/wrong-effect failures.
- Use server-managed handles for document/model objects rather than relying on display names or long mutable paths.
- Use generation/version-scoped topology references and reject stale references before mutation.
- Provide deterministic recovery for supported reversible operations. Do not depend on localized UI command strings for Undo.
- Treat modal dialogs, timeouts, and indeterminate COM completion as session-health events, not ordinary retryable exceptions.
- Keep CAA/native access behind typed adapters; do not expose raw native/COM pointers across the MCP boundary.
- Do not classify a capability as production-supported until schema tests, failure-path tests, and relevant live CATIA validation pass.
Reference loading
Read references/repository-contract-gaps.md before modifying an existing tool or capability group.
Read references/production-architecture.md before changing COM/session execution, object lifecycle, recovery, topology, diagnostics, or CAA integration.
Read references/result-contract.md before adding or changing tool outputs/errors.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

catia-v5-mcp-maintainer is a skill published in the GitHub repository daiemon12/catia-v5-mcp-server (94 stars, last pushed yesterday), licensed MIT. It adds 85 tokens to every session and 1,801 once invoked, about $0.0004 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 2026-08-30.
