- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.

  - Actively maintained (last published 11 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 135 tokens (~135/item across 1 items; 1 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.

Budgetary: estimate token spend

Return a pre-flight, probabilistic token-spend estimate for a coding task before you run it, and store it so the realized cost can be recorded afterward. Call this with the user's task described in natural language. Returns a token range (p10–p90), a scenario label, and a confidence score. This tool only estimates and records — it never reports how many tokens a run actually used.

Input parameters:

- `model` (string): Optional target model identifier (e.g. claude-opus-4-7). Omit to use the account default.
- `query` (string, required): Natural-language description of the coding task to estimate.
