AC modular-skill-groups
Organize, activate, and switch between modular skill groups to keep context windows clean. Use when (1) asked to activate a skill group or switch groups, (2) context window is getting polluted with unused skills, (3) starting a new project phase that needs a different skill focus, (4) listing available skill groups or skills within a group, (5) onboarding a new skill and deciding which group it belongs in. Triggers on: "switch to [group]", "activate skill group", "what skills do I have", "modular skills", "skill groups", "load skills", "context window too big", "too many skills".
As a process C 59/100 · Has gaps — weak spots: result and completion, inputs and preconditions, failures and branches
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 59/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 70When it triggers. States when to use, but not when not to
- 100Tools and files. No external tools needed
- 100Steps. 8 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 380 tokens
- 100Running it twice. No mutating operations
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.
