Conciseness

Mostly efficient with well-sectioned guidance, but the '令牌优化模式' section (trigger-table lazy loading, context-composition awareness, duplicate-instruction detection, external tools like token-optimizer MCP and context-mode) is tangential to the skill's core purpose of manual compaction timing and adds unnecessary tokens. Not 4 because this off-topic padding is noticeable; not 2 because the core sections are not heavily padded.

Actionability

Provides copy-paste-ready hook JSON for settings.json, a concrete config env var with a default (COMPACT_THRESHOLD=50), and specific script behavior (threshold at 50 calls, reminders every 25). Minor gap: the actual script source is not shown. Not 5 because some guidance remains advisory and no full executable script is included.

Workflow Clarity

The decision table and best-practices list give a clear sequenced 'compress here, not here' flow with checkpoints such as 'write before compacting' and 'the hook says when, you decide whether'. Not 5 because there is no explicit validate→fix→retry feedback loop; not 3 because checkpoints are present and the sequence is clear. The destructive/batch cap does not apply since this is advisory, not a destructive operation.

Progressive Disclosure

Well-organized into clear sections with a '相关' links section; no bundle files are present in references/scripts/assets, and the body appropriately keeps most content inline. Not 5 because the tangential token-optimization section and an external Twitter link keep it from being a clean overview, and there are no one-level-deep bundle references to signal.

Specificity

Names the domain (context compaction) and 1-2 concrete actions (manually compact at logical intervals, preserve context across task phases), but does not list several specific actions. Not 2 because actions are present beyond a generic domain label; not 4 because coverage is not comprehensive.

Completeness

Has a clear 'what' (manually compact context at logical intervals to preserve it across task phases) but no explicit 'Use when...' trigger clause; the 'when' is only weakly implied by '在任务阶段中'. Per guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Includes relevant keywords like '压缩上下文' (compact context), '逻辑间隔' (logical intervals), '任务阶段' (task phases), and '自动压缩' (auto-compaction), but misses common variations/synonyms such as '/compact', 'context window', or 'long session'. Not 4 because keyword coverage lacks several natural terms a user would say.

Distinctiveness Conflict Risk

Targets a clear niche (strategic manual compaction vs arbitrary auto-compaction) that is mostly distinct with only minor overlap risk against related context-management skills. Not 5 because trigger phrasing is not maximally concrete; not 3 because it is more distinguishable than 'somewhat specific'.
