Conciseness

The body is a lean index with no padding: every line carries Trellis-specific knowledge Claude cannot already know (scope semantics, deprecated --linked-context-* terminology, the --kind done vs --tag dispatcher gotcha, --raw for audit). It never explains generic concepts, matching the 'lean and efficient; every token earns its place' anchor.

Actionability

First Commands are copy-paste-ready bash commands and the intent table maps user phrasings directly to specific reference files. Score is 4 rather than 5 because the common creation/spawn workflows (e.g. channel create, channel spawn) are only delegated to references rather than shown, leaving minor gaps in executable coverage.

Workflow Clarity

A clear sequence is present: run --version/--help, list channels, 'inspect it before asking for background' as an explicit checkpoint, then route by intent table into core rules. No validation loops are required since destructive operations (kill, interrupt) are delegated to workers.md rather than instructed inline, but the checkpoint coverage is implicit rather than exhaustive, fitting anchor 4.

Progressive Disclosure

The body explicitly declares itself an index ('This skill is an index. Load only the reference file for the current job'), provides a Route By User Intent table, and lists all five reference files with one-line summaries. All five referenced files exist on disk and contain no nested references, so navigation is one level deep and unambiguous.

Specificity

The description lists several specific capability areas — 'spawned workers, cross-agent review, progress inspection, forum channels, and channel log debugging' — with only minor coverage gaps, matching anchor 4. It falls short of anchor 5 because these are capability nouns rather than fully concrete actions, and beyond anchor 3 because more than 1-2 concrete areas are named.

Completeness

The 'what' is clear and reasonably comprehensive (live multi-agent collaboration with enumerated capabilities), but there is no 'Use when...' clause or equivalent explicit trigger guidance, capping completeness at 3 per the judging guidelines. It is above anchor 2 because the 'what' is concrete, not vague.

Trigger Term Quality

Terms like 'spawned workers', 'cross-agent review', 'multi-agent collaboration', and 'channel log debugging' map well to natural user phrasings, giving good keyword coverage. It is not anchor 5 because common synonyms users would actually say are missing (e.g. 'brainstorm', 'agent stuck/stalled', 'check progress', 'issue board').

Distinctiveness Conflict Risk

Naming 'Trellis channel' plus its specific capability areas establishes a clear niche with distinct triggers, fitting anchor 4 ('mostly distinct; minor overlap risk'). It does not reach anchor 5 because the broad phrase 'live multi-agent collaboration' could overlap with other agent-orchestration skills in the absence of an explicit when-clause.
