Conciseness

The ~55-line body is lean and assumes Claude's competence: every sentence carries a tool name, flag, or behavioral rule ('Installs can outlast tool timeouts, so create with install: false'), with no explanations of concepts Claude already knows and tables used where prose would bloat.

Actionability

Guidance is fully executable: exact MCP tool names (bts_plan_project, bts_get_schema, bts_add_addons), exact commands (npx create-better-t-stack@latest schema --name createInput, create-json with dryRun), and exact flags (install: false), with complete copy-paste payloads one reference away in references/cli.md.

Workflow Clarity

Both the 7-step create and 4-step change workflows have explicit validation checkpoints and feedback loops: plan/dryRun before writing, 'If the plan fails, its error names the conflict. Fix the config and plan again', user confirmation ('get a yes'), and 'Prove it runs... If a step fails, report the exact error.'

Progressive Disclosure

The body is a well-organized overview that splits detail into two clearly-signaled, verified, one-level-deep references — references/options.md (values and compatibility rules, with the schema named as source of truth) and references/cli.md (full payloads, flag form, Stack Builder keys) — with no further nesting.

Specificity

Names the domain and two distinct concrete actions ('Create or extend an end-to-end type-safe TypeScript project', 'add addons or a workspace package') that comprehensively cover what the tool does, but it does not enumerate the multiple specific actions of the level-5 anchor.

Completeness

Explicitly answers 'what' ('Create or extend an end-to-end type-safe TypeScript project with Better-T-Stack') and 'when' with two concrete 'Use when...' clauses covering both new projects and existing bts.jsonc projects.

Trigger Term Quality

Covers natural synonyms ('start, scaffold or bootstrap'), project shapes ('app, API, fullstack project or monorepo'), twenty framework/ORM/auth names users actually say, and the 'bts.jsonc' file marker — comprehensive coverage including synonyms and a file extension.

Distinctiveness Conflict Risk

The named tool and scaffolding niche are distinct, but 'with any of Next.js, TanStack Router or Start, ... Hono, Express, Fastify' creates minor overlap risk where a generic framework-app request might pull this skill when a plain framework scaffold is wanted; not the minimal-conflict level-5 anchor.
