Conciseness

The body is dense and imperative — tables of tools, parameter rules (`ql={-runs}`), and short decision rules with no explanations of concepts Claude already knows. Minor trimmable redundancy remains: the read-only rule appears in Role, Flow, and Pitfalls; "never retry a call unchanged" is stated twice; and the time-sensitive `plugin_version="0.19"` is inlined. This puts it at anchor 4 (efficient with minor instances that could be trimmed) rather than the every-token-earns-its-place anchor 5.

Actionability

Guidance is fully executable for an instruction-only skill: exact MCP tool names, exact required parameters ("agent_id required… ql={-runs} always"), a concrete default ("the last 14 days, all test results in the period"), an explicit stop-and-say rule for missing data, and a literal output-contract JSON template with markers. Per the rubric's scoring note, absence of code is not penalized when guidance is this actionable.

Workflow Clarity

The 11-step Flow is clearly sequenced with explicit validation checkpoints: resolve the agent "before any data call", "Check what data exists — before fetching the numbers", the fix-once-then-stop retry rule ("Never retry a call unchanged"), and a mandatory closing quality check ("fix every failure. It is not optional.") that acts as a validate→fix→re-check feedback loop. This matches the anchor-5 pattern of explicit validation steps and error-recovery loops.

Progressive Disclosure

The body is a clear overview with three one-level-deep references (data.md, v0-report-format.md, writing.md — all present in the bundle), each summarized in Additional Resources and cited with accurate section pointers (e.g., "references/writing.md § Quality check", "references/data.md § Grouping") that were verified to exist in the actual files. Structure matches the well-signaled one-level-deep anchor.

Specificity

The description names the domain ("a report on existing test results shaped by a purpose") and enumerates many concrete report variants ("a weekly status report, a leadership summary, how responsive / secure / accurate the agent is… comparing agents"), plus an explicit constraint "Reads existing results only; never runs tests". It is one core action with concrete variants rather than multiple distinct actions, fitting anchor 4 rather than the comprehensive multi-action coverage of anchor 5.

Completeness

It explicitly answers "when" with an explicit "Use when the user asks for…" clause containing concrete trigger phrases, and "what" with "a report on existing test results… Reads existing results only; never runs tests", plus a clear boundary ("For testing an agent from scratch use /cekura-report"). This matches the anchor-5 example pattern of both what and when with concrete triggers.

Trigger Term Quality

Strong natural phrasing users would actually say: "weekly status report", "leadership summary", "frustrated callers", "only P0 flows", "only failed calls", "comparing agents", "a topic such as refunds", "'report on this result'". Common synonyms like "test summary", "eval report", or "QA report" are missing, so it falls just short of the comprehensive synonym coverage of anchor 5 and above anchor 3's partial keyword set.

Distinctiveness Conflict Risk

"Reads existing results only; never runs tests" plus the explicit /cekura-report boundary give it a clear niche with mostly distinct triggers. However, "frustrated callers" reads like production-call-log territory (the cekura-flag-call-log-failures skill's domain) without disambiguation, leaving minor overlap risk with a closely related skill — anchor 4, not the minimal-conflict anchor 5.
