Conciseness

The body is largely efficient — tables carry the framework, flag, port, and next-step information, and no space is spent explaining what agents or AWS are. A few passages could be trimmed, e.g. the four worked name-length examples ('MyCustomerSupportAgent is 22 chars and fits...') and the 'Framework vs. model provider — a common confusion' explainer, which pushes it below anchor 5's 'every token earns its place' but above anchor 3's 'some unnecessary explanation'.

Actionability

Every step gives copy-paste-ready commands: 'agentcore create --name <ProjectName> --defaults', a full flag reference table with values and defaults, exact port numbers, concrete error-recovery guidance ('grep ps / check the CLI banner if invocations start failing'), and a ready-to-present example command block. This matches anchor 5's 'fully executable; copy-paste ready... specific examples cover the common cases'.

Workflow Clarity

Steps 0–7 are clearly sequenced with explicit validation checkpoints and feedback loops: re-checking 'agentcore --version' after update, validating the project name before constructing the command, presenting the command for confirmation before running, and port-conflict recovery for dev failures. This matches anchor 5 ('explicit validation steps; feedback loops for error recovery'), and no destructive/batch cap applies since deploy requires confirmation.

Progressive Disclosure

The single bundle reference (references/example-support-agent.md) is one level deep and clearly signaled via a task-mapped table, and cross-skill links (../agents-build/references/migrate.md) are explicit. However, the main file at ~340 lines inlines substantial peripheral content — the 'Framework not listed?' table, BYO Container workflow, language-specific notes — that could live in references to slim the overview, matching anchor 4's 'most content appropriately placed; minor organization gaps' rather than anchor 5's clean overview/split.

Specificity

The description lists four concrete, lifecycle-complete actions — 'Handles framework selection, project scaffolding, first deploy, and first invocation' — which comprehensively cover the skill's scope from zero to a running agent. It matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' rather than score 4, whose coverage has minor gaps.

Completeness

Both 'what' ('Handles framework selection, project scaffolding, first deploy, and first invocation') and 'when' (an explicit 'Use when a developer wants to...' clause plus a 'Triggers on:' list of concrete phrases) are clearly and explicitly answered. Score 4 would require the 'when' to be less explicit; here it is maximally explicit.

Trigger Term Quality

It enumerates fifteen natural phrases users would actually say ('build an agent', 'get started', 'hello world agent', 'first agent', 'dev server', 'what port', 'Strands vs LangGraph'), including CLI-specific terms and synonyms. This is comprehensive coverage including variations, matching anchor 5 rather than anchor 4's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The description carves out a clear niche (new-project creation) and actively disambiguates against sibling skills: 'Not for adding capabilities to existing projects — use agents-build or agents-connect', migration-context and existing-MCP-server routing. Triggers are specific to greenfield intent, so conflict risk is minimal — matching anchor 5 rather than anchor 4's 'minor overlap risk'.
