Conciseness

The body is dense, procedural, and assumes competence (no padding explaining diffs, juries, or provenance), but the 'Key Rules' section restates the three non-negotiable rules and the Step 2 constraints (Write/Edit-only, backup, cross-family, human-invoked-only) nearly verbatim. This duplicated rule material plus the dense opening blockquote on reviewer routing could be tightened, matching 'mostly efficient but includes some unnecessary explanation'.

Actionability

Concrete and mostly executable: the staging check bash block, exact jury invocation parameters (model, reasoning-effort config, read-only sandbox), the provenance stamp command with arguments, the log record shape, and exact paths (.aris/meta/pending, backups, optimizations.jsonl). Not 5 because 'Apply the diff by Edit/Write on the target corpus file' and the jury prompt text are described rather than given as copy-paste-ready procedures.

Workflow Clarity

Clear Step 0→3 sequence with validation checkpoints appropriate to a destructive/batch operation: fresh jury PASS gate, cross-family assertion that must not raise, backup before every mutation, stamp re-assertion, and 'any failure ⇒ skip & report, never silently apply'. Validation is present so the destructive-op cap at 3 does not apply; the gap is that translating a staged .diff into Edit/Write operations is left implicit rather than a spelled-out fix-and-retry loop.

Progressive Disclosure

Good structure with clearly signaled, one-level-deep references at point of use (reviewer-independence.md, review-scope-limits.md, integration-contract.md, review-tracing.md, reviewer-backends.md) and the workflow core kept inline where it belongs. Minor gaps: the reviewer-routing blockquote at the top is dense and reads as an embedded contract rather than a pointer, and the helper-resolution chain is described in prose instead of one canonical path.

Specificity

"Privileged applier that LANDS meta-optimize / corpus-audit patches the user approved" and "mutate the skill corpus from a self-modification proposal, with cross-model jury and human approval at landing" list several concrete actions in a named domain. Falls short of 5 because emphasis phrases ("the ONLY skill permitted") displace coverage of what landing actually involves (backup, provenance stamp, report).

Completeness

Explicitly answers what ("Privileged applier that LANDS ... patches ... mutate the skill corpus ... with cross-model jury and human approval") and when ("Use when the user says 'meta apply', '/meta-apply', 'land the staged patches', '应用优化', after a /meta-optimize run") with concrete trigger phrases. Both halves are explicit, so neither the 3-cap for a missing when-clause nor a 4 for a weak when applies.

Trigger Term Quality

Includes natural trigger phrases users would say: "meta apply", "/meta-apply", "land the staged patches", "应用优化", plus the "/meta-optimize run" precondition. Not 5 because common English variations like "apply the patches" or "apply optimization" are absent while a non-English synonym is present.

Distinctiveness Conflict Risk

Occupies a clear niche (privileged landing gate for self-modification patches) with distinct triggers that explicitly separate it from the read-only producer ("land the staged patches" vs. optimize). The quoted trigger phrases are unlikely to collide with any other skill's invocation.
