Conciseness

The body is dense, normative rule-writing with no padding and no explanations of concepts Claude already knows; nearly every bullet adds framework-specific policy. It is not anchor 5 because the ~20-line 'First use: read-only version check' protocol is trimmable meta-procedure that spends tokens on a check rather than the skill's core competence, but that alone is minor, keeping it at anchor 4 rather than dropping to 3.

Actionability

Concrete, executable guidance is present: exact API shapes ('.image(question=..., file=...|url=...|files=[...]|urls=[...])', '.auto_continue()', the '.input(...) .info(...) .instruct(...) .output(...)' chain order, '[[ref:<ref_id>]]' citations) plus per-concern routing to reference files. It is not anchor 5 because several bullets remain abstract principles ('Derive a general invariant and test contrasting cases', 'Prioritize developer understanding') with no worked example inline, and full executable detail is deferred to references.

Workflow Clarity

For a contract/policy skill, the sequence is clear: routing rules to the right sibling skill, a canonical request chain order, and explicit validation checkpoints ('Validate schema, offered keys, authorization, and deterministic constraints before a real call or side effect') with failure recovery ('After measured schema/ensure/length failures, consider a shallower model-facing projection ... '). It misses anchor 5 because there is no end-to-end sequenced workflow with feedback loops; the checkpoints are distributed across bullets rather than forming an explicit ordered process.

Progressive Disclosure

The 'Read by Need' section is a well-signaled, one-level-deep map from each concern to a specific reference file, and all eight cited references/ files exist in the bundle. It falls short of anchor 5 because two navigation links leave the bundle to sibling skills that do not resolve in this package copy ('../agently/references/context-and-skills.md', '../agently-collaboration/SKILL.md'), making part of the navigation unverifiable from the skill root.

Specificity

The description enumerates many concrete capability areas ('model settings, Prompt/input/output design, effect tuning, ... structured output, LongContent, auto_continue, response reuse, streaming, TTS/STT audio, session memory, embeddings, and retrieval'), giving broad, specific coverage of its domain. It stops short of anchor 5 because these are mostly topic nouns rather than concrete verb-phrased actions, and it does not reach anchor 5's fully action-oriented comprehensiveness.

Completeness

Both halves are present: the 'what' is the enumerated request-side setup and contracts list, and an explicit 'Use for...' clause provides trigger guidance (so it is not capped at 3). The 'when' is a capability category ('within one request family') rather than concrete user scenarios or mentionable phrases, matching anchor 4 ('when could be more explicit or specific') rather than anchor 5.

Trigger Term Quality

Good natural keywords users of the framework would say ('structured output', 'streaming', 'session memory', 'embeddings', 'TTS/STT audio', 'model settings'), but several entries are internal jargon ('LongContent', 'auto_continue', 'effect tuning') and common synonyms or phrasing variations are missing. This fits anchor 4 ('good keyword coverage; a few natural terms missing') better than 3 or 5.

Distinctiveness Conflict Risk

It carves a clear niche ('request-side setup and contracts ... within one request family') and explicitly redirects overlapping work: 'Use agently-agentic-design for cross-node data flow and model/Host ownership.' This is a clear niche with distinct triggers and minimal conflict risk, matching anchor 5 exactly.
