Conciseness

The 14-line body is lean and every sentence does work: two routing steps ('read `commands/{command}.md` and follow it', 'read `skills/controller.md`'), a compact failure policy, and one-sentence pointers to guidelines and the scripts helpers. There is no explanation of concepts Claude already knows and no padding, matching the 'every token earns its place' anchor rather than the level below with 'minor instances of over-explanation'.

Actionability

The routing instructions are concrete ('read `commands/{command}.md`', 'read `skills/controller.md`') and the failure policy is explicit, but key execution details are missing: the scripts paragraph ('The `scripts/` helpers compact source data, validate AI judgments...') gives no invocation syntax for any of the six bundled scripts, and 'route it through the phase dispatcher' is abstract. This matches 'some concrete guidance but incomplete; missing key details' rather than the level above, where gaps would be minor.

Workflow Clarity

A rough sequence exists (command dispatch, else controller routing) and a generic feedback loop is stated ('If a step fails or produces unexpected output... stop and report the error... Do not advance to the next phase. Offer to retry... or escalate'). However, this skill orchestrates batch operations (batch sizing all Features in a Fix Version) and writes results back to Jira, yet the actual phase sequence (ingest → assess → apply) is only implied by command names, and no explicit validation checkpoint before writing back to Jira appears in the body — the files that would contain the phase workflow are absent from the bundle. Per the batch-operation feedback-loop cap, this cannot exceed 3.

Progressive Disclosure

The SKILL.md itself is well structured as a lean dispatcher with clearly signaled one-level-deep references ('For principles, hard limits, safety, quality, and escalation rules, see `guidelines.md`'), and the `scripts/` directory genuinely contains the six helpers described. But scored against the actual bundle, the primary referenced paths — `commands/{command}.md`, `skills/controller.md`, and `guidelines.md` — do not exist in the bundle, so navigation dead-ends at the main routing targets. That is more than the 'minor organization gaps' of the level above, while the clear signaling and real scripts/ content keep it above the level below.

Specificity

The description lists multiple concrete actions covering the full workflow end-to-end: 'assesses Features from Jira using T-shirt sizes (XS–XXL)', 'produces per-team effort breakdowns (DEV, QE, UX, UI, DOCS)', 'writes results back to Jira', and 'Accepts a single Feature or all Features in a Fix Version for batch sizing'. This matches the anchor for multiple specific concrete actions with comprehensive coverage; it is not the level below because there are no minor gaps — input, method, output, and write-back are all named.

Completeness

Both questions are answered explicitly: the 'what' ('assesses Features from Jira using T-shirt sizes... writes results back to Jira') and the 'when' ('Use when sizing Features for cycle planning, prioritizing a release backlog, or evaluating whether a Feature fits in a cycle'), with concrete trigger phrases and activation commands (/ingest, /assess, /apply). This clearly matches the top anchor rather than the level below, where the 'when' would be less specific.

Trigger Term Quality

Natural phrases users would say are well covered: 'sizing Features', 'cycle planning', 'prioritizing a release backlog', 'evaluating whether a Feature fits in a cycle', plus domain terms 'Fix Version' and 'Jira'. It falls short of the top anchor because common synonyms such as 'estimate/estimation', 'story points', or 'sprint planning' are absent, leaving a few natural terms missing.

Distinctiveness Conflict Risk

The description occupies a clear niche — Jira Feature sizing with T-shirt sizes, per-team effort breakdowns, and specific activation commands — so it is unlikely to trigger for the wrong skill. It matches the 'clear niche with distinct triggers; minimal conflict risk' anchor rather than the level below, which would require overlap risk with closely related skills.
