Conciseness

The body is dense and almost entirely Trellis-specific with no filler explanations of concepts Claude already knows, but the same facts are restated across sections: the channel event log path appears three times, '.trellis/agents/{check,implement}.md' in six places, and the trellis mem sources and getBundledSkillTemplates() twice each — the ~180-word v0.6 overview sentence alone re-describes what References and Current Rules repeat. This is more than 'minor instances that could be trimmed', placing it below the efficient anchor.

Actionability

Guidance is highly concrete throughout — executable commands ('task.py create --parent <slug>', 'trellis workflow --template <id>', 'trellis mem list | search | context | extract | projects'), exact config keys (channel.worker_guard.idle_timeout, hooks.after_create), and specific file paths. The gap is that 'references/local-architecture/multi-agent-channel.md' and 'references/local-architecture/bundled-skills.md' are referenced in How To Use and References but absent from the bundle, leaving those navigation steps unexecutable.

Workflow Clarity

The 'How To Use' section gives a clear, conditionally routed 5-step sequence with explicit validation ('Before editing, read the actual files in the user project and treat local content as authoritative' and 'cross-check against the local .trellis/config.yaml and the installed CLI's trellis --help'). It falls short of the top anchor because there are no error-recovery feedback loops and step 3 directs the reader to a reference file that does not exist in the bundle.

Progressive Disclosure

The structure is exemplary — a lean overview body, a routing section, and ~20 one-level-deep references each annotated with a one-line description. Scored against the actual bundle, however, two of the referenced paths (references/local-architecture/multi-agent-channel.md and references/local-architecture/bundled-skills.md) are missing, which breaks navigation for the multi-agent channel and bundled-skills topics and drops it below the clear-and-complete top anchor.

Specificity

The description names the domain ("local Trellis architecture") and only two concrete actions — "Understand and customize" — while the enumerated targets (.trellis, hooks, agents, skills, trellis channel, trellis mem) are specific, the verbs themselves are generic. It does not list several specific actions, so it sits at the anchor for 'domain plus 1-2 concrete actions' rather than the level above.

Completeness

Both parts are explicit: 'what' is stated concretely ("Understand and customize the local Trellis architecture inside a user project") and 'when' is given by a literal "Use when modifying..." clause enumerating concrete trigger surfaces. This matches the top anchor exactly.

Trigger Term Quality

Comprehensive natural-term coverage including the directory path (.trellis), CLI command names (trellis channel, trellis mem, trellis init), feature names users would actually say (hooks, settings, agents, skills, commands, prompts, workflows, workflow templates, spec refresh), and bundled skill names. These are the exact phrases a Trellis user would naturally say when needing this skill.

Distinctiveness Conflict Risk

The description is anchored to a clear Trellis niche with distinct triggers (trellis channel, trellis mem, .trellis/agents), but the mid-list generic terms 'hooks, settings, agents, skills, commands, prompts, workflows' overlap with generic platform-configuration skills, creating minor wrong-skill trigger risk — mostly distinct rather than fully minimal-risk.
