measure: statement for ASu-skills v0.3.0 (plugin, claude_code)

[Zeming-Yuan]

Following #64 — a report for a plugin I use daily: ASu-skills v0.3.0, six skills for a Chinese-language job-search workflow (open-source contribution, résumé rewriting, résumé generation, interview prep, offer tracking).

Produced with:

context-report produce --subject <asu-skills-0.3.0> --kind plugin --target claude_code

Rows

attribute	result	note
cost.context_tokens	PASSED	4,891 tokens across 6 files (make-resume 1,566 … offer 354)
reachability, fault.scriptMissing, fault.interpreterMissing, fault.timeout, fault.malformedOutput, cost.latency_ms	NotApplicable	"the plugin declares no hooks"
conformance, decision, interference	NotAvailable	v0.1 producer does not produce these
efficacy	NotAvailable	paired ablation not run

What I expected vs. what the statement says

I expected the report to answer "does this plugin work in Claude Code?". Instead, ten of eleven rows say the question was not measured, and the one that was measured is a token count. The NotApplicable/NotAvailable split is doing its job — none of this reads as a defect — but the shape is worth recording: a skills-only plugin is probably the most common subject kind for this format, and this is what its report looks like today.

Two things I did not expect:

1. conformance is NotAvailable. Whether the bundle loads at all in the target agent is the first question I would ask of a plugin report, and it is the one row v0.1 cannot produce.
2. cost.context_tokens counts six SKILL.md files, but a skill body is only injected when the skill is invoked. The row question is "how many tokens does this artifact add to the agent context window" — for a skills bundle, the always-on surface is the frontmatter, not the full files. conditions does say files: 6, so the report is not misleading on its own terms; I raise it as a question about which surface this row is meant to name.
