Conciseness

The ~85-line body is dense throughout with zero explanation of concepts Claude already knows ("The data already exists in CDP: there is no workflow and no model.") and uses tables for scanability. The Quick Reference's repetition of a few facts is deliberate lookup structure rather than padding, so the lean/every-token-earns-its-place anchor fits better than 4's trimmable over-explanation.

Actionability

Guidance is executable: copy-paste commands ("tdx auth status", "tdx ps desc \"<PS>\" -o agent_outputs/<project_slug>/schema.json"), exact template placeholders ({{parent_segment_id}}, {{engagement_dir}}), and exact thresholds ("≥ 9/10 Pass", "at least 3 on the customer's definitions", "at least 2 Compliance cases"). The single in-body ellipsis ("tdx sg list -r …") is completed verbatim in the referenced references/discovery.md, so there is no real gap; 4 would require missing key details, which the verified reference files close.

Workflow Clarity

Five phases are sequenced in a summary table and expanded per phase, with an explicit feedback loop ("Score, record the round, propose fixes with the failure → fix table, apply on approval, rebuild, re-run — until ≥ 9/10 Pass"), approval gates ("show it; ask for permission to run"), and a hard finalization gate ("if any remain, say what is missing and do not finalize"). Batch and destructive operations are guarded ("segment prompts stop at validate + dry-run", push only on approval), so the destructive/batch validation cap does not apply and the content matches the anchor-5 validate-fix-retry pattern.

Progressive Disclosure

Scored against the actual bundle: all five references/ files exist and are each signaled in the body with their purpose ("references/agent-setup.md (placeholders, build checks, agent files table)"), are one level deep, and are dense and self-contained (verified in discovery.md and eval-setup.md). External ../shared/* and project_templates/ paths are direct one-hop references the body says when to read, so nothing is buried through nesting; this fits anchor 5's clear-overview, well-signaled structure.

Specificity

The description lists multiple concrete actions covering the full lifecycle: "explores attributes, behaviors and existing segments", "drafts the business context (key terms, conversion events, product categories, lead definitions, compliance and exclusion rules) and data dictionary", "builds the agent into the Work Folder's .claude/skills/", and "evaluates it with ten customer-specific test prompts". Coverage spans start, set up, update, rebuild and evaluate with no phase missing, matching the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

Both questions are answered explicitly: the what is the multi-clause action description, and the when is "Use it to start, set up, update, rebuild or evaluate the audience agent. Trigger on: …" with concrete trigger phrases. This matches the anchor-5 example structure exactly; 4 would require the when to be merely present but less explicit, which is not the case.

Trigger Term Quality

Eleven natural trigger phrases are given — "set up an audience agent", "rebuild the audience agent", "run audience agent eval", "an AI analyst for our parent segment", "build an audience agent for [customer]" — covering verb synonyms (set up/start/build/rebuild/update/test) and the way marketers actually phrase the request. No common natural variation is obviously absent, so it meets the comprehensive-synonyms anchor rather than 4's "a few natural terms missing".

Distinctiveness Conflict Risk

The niche is unambiguous ("customer-specific audience agent on any Treasure AI CDP parent segment") and the one real overlap risk — with the installed project agent this skill creates — is explicitly resolved: "Once the project's audience agent is installed, audience and segment analysis questions go to it." That explicit routing keeps conflict risk minimal, fitting anchor 5 rather than 4's minor-overlap framing.
