Conciseness

The body is dense and fact-per-line (Current Rules bullets give exact paths, config keys, and commands) with almost no explanation of concepts Claude already knows. Not 5 because there is notable redundancy: the v0.6 surfaces (workflow templates, channel runtime, trellis mem, bundled agents) are described in the opening paragraph and again across the References and Current Rules sections.

Actionability

Copy-paste-ready commands appear throughout (`trellis channel spawn --agent <name>`, `task.py create --parent <slug>`, `trellis workflow --template <id>`, `trellis mem list | search | context | extract | projects`) alongside exact config keys (`channel.worker_guard.idle_timeout`, `registry.spec.source`) and exact file paths. As an instruction-only skill the guidance is fully executable and covers the common cases.

Workflow Clarity

"How To Use" gives a clear sequenced navigation workflow with conditional branching and a pre-edit checkpoint ("Before editing, read the actual files in the user project and treat local content as authoritative"), plus a cross-check rule ("cross-check against the local `.trellis/config.yaml` and the installed CLI's `trellis --help` before claiming a knob exists"). Not 5 because error-recovery feedback loops are implicit — e.g., what to do when `.trellis/.template-hashes.json` reports user-modified conflicts is only partially covered by the `.new` sidecar rule.

Progressive Disclosure

All 23 referenced files exist, are one level deep, grouped into three clear sections, and each carries a one-line description — strong overview navigation. However, 17 of the 40 bundle files under references/ (claude-code/, core/, how-to-modify/, meta/) are not reachable from any navigation in SKILL.md, and how-to-modify/ appears to be a stale pre-v0.6 duplicate of customize-local/, which is a real organization gap that keeps this below anchor 5.

Specificity

Actions are limited to two generic verbs ("Understand and customize"), but the targets are specific and comprehensive (`.trellis`, `.trellis/agents/`, `trellis channel`, `trellis mem`, `trellis init`, named bundled skills). Matches anchor 4 (several specific targets, minor coverage gaps) rather than 3 because the surface coverage is thorough, and not 5 because the operations themselves are not distinct concrete actions like 'extract' or 'merge'.

Completeness

Clear what ("Understand and customize the local Trellis architecture inside a user project") plus an explicit, itemized when-clause ("Use when modifying .trellis plus platform hooks, settings, agents, skills, commands, prompts, workflows, ...") with concrete trigger phrases. Matches the anchor-5 example pattern exactly; not 4 because the when-clause is explicit rather than merely present.

Trigger Term Quality

Good natural-term coverage: "Trellis", ".trellis", "hooks", "settings", "agents", "skills", "commands", "prompts", "workflows", "workflow templates", "cross-session memory". Not 5 because phrases like "bundled-skill auto-dispatch flow" and "registry-backed spec refresh" are internal jargon users would not naturally say, and simple synonyms ("change", "edit", "configure") are absent.

Distinctiveness Conflict Risk

Distinct Trellis-anchored triggers ("trellis channel", "trellis mem", ".trellis/agents/", named bundled skills trellis-channel/trellis-session-insight/trellis-spec-bootstrap) define a clear niche with minimal conflict risk. The generic middle terms (hooks, settings, agents) are all scoped under Trellis modification, so it does not fall to anchor 4.
