AB saturnday
Governed AI software execution — 48+ deterministic governance checks for Python with additional checks for TypeScript, DevOps, and project metadata. LLM-powered security triage to filter false positives. Build projects from a brief with per-commit governance, produce governed documents, inspect release artefacts, or auto-fix findings. Six backends — Claude Code, Codex, OpenClaude, Cursor, OpenAI API, Anthropic API. Requires pip install saturnday.
As a process B 77/100 · Nearly there — weak spots: when it triggers, running it twice
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 77/100
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 11 mutating operations with no state check
- 60Tools and files. Uses tools (bash, python) that frontmatter does not declare
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 37 steps
- 100Result and completion. Output format and completion criterion are stated
- 100Failures and branches. 3 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1907 tokens
- 100Progress reporting. Reports progress
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
Quality signals
