AA ax-development
Agent Experience (AX) development framework. Apply when building libraries, CLIs, APIs, or any software that will be consumed by AI agents — not just humans. Covers: deterministic design, machine-readable contracts, fail-fast validation, composable primitives, documentation co-location. Use when: (1) starting a new project/lib that agents will use, (2) reviewing code for agent-friendliness, (3) designing CLI output contracts, (4) structuring error handling for machine consumption, (5) writing tests for deterministic behavior.
As a process A 81/100 · Runs to the end — weak spots: progress reporting
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 81/100
- 0Progress reporting. Says nothing while it works
- 50Failures and branches. 0 branches, has a failure section
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Tools and files. No external tools needed
- 100Steps. 13 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1245 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.
