Use for general product implementation work that is not primarily backend architecture, pure integration wiring, or screenshot-driven design-to-code.
Use when the main deliverable is maintainable documentation such as repository rules, onboarding guides, runbooks, ADRs, or architecture notes.
Use on first entry to a new repository to run environment scanning and ask targeted boundary questions before implementation.
Use after writing or modifying code to enforce the mandatory write → test → fix → repeat validation cycle.
Use before committing to a design or plan to force assumption-surfacing. The agent challenges your design, questions edge cases, and flags gaps — you patch vague decisions. Prevents the failure mode where a design "feels explained" but contains hidden flaws that only appear during implementation.
Use to establish and maintain a shared domain glossary (UBIQUITOUS_LANGUAGE.md). Creates a single source of term definitions that all agents, prompts, and documents must use — preventing semantic drift and repeated re-explanation across sessions.

Use this skill to build a mental model of the codebase before making changes.
ARCHITECTURE.md if it exists. At minimal profile for single-file Small tasks: skip ARCHITECTURE.md unless it is referenced by the task description or appears to contain non-template content (>50 lines of substantive text).CONTRIBUTING.md or equivalent docs if they exist.Read at least one existing file in each layer you will modify and note:
Before cross-file changes:
project/project-manifest.md for project-local constraints.DECISIONS.md if it exists.After discovery, produce a brief summary:
Modules involved: [list]
Existing patterns: [key observations]
Constraints: [project-specific rules that apply]
Files to read before coding: [list]
Before completing codebase exploration, verify:
project/project-manifest.md and DECISIONS.md were checked for constraints
