SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning an approved design into working code often drifts into ad-hoc edits, skipped tests, and lost context. This Skill converts an approved design or requirements into a structured, file-level implementation plan and executes it with disciplined TDD, task tracking, and verification gates. ## Core Features & Use Cases - Structured Planning: Decomposes work into bite-sized tasks with exact file paths, tracer-bullet first slices, and explicit batch dependencies. - TDD Execution Rhythm: Defaults every task to red-green-refactor, with explicit exceptions for config, migrations, and docs. - Parallel Batch Dispatch: Groups independent tasks and dispatches subagents with workspace isolation, placement protocols, and clean committed handoffs. - Checkpoint & Resume: Writes human-readable checkpoint artifacts and latest-pointer state so work can resume after a context reset. - Use Case: After a design doc is approved for a new API feature, invoke this Skill to produce a task plan, track each task in the host's todo system, implement with TDD, and verify the full suite before handoff. ## Quick Start Ask the agent to implement the approved design for the current ticket using the implement skill and follow the plan with TDD.

FAQPage Schema
How do I turn an approved design into an implementation plan?▼

Invoke the implement skill with an approved design artifact path or a blueprint-approved pointer. It reads the design as primary input, decomposes work into 2-5 minute tasks with exact file paths, and groups independent tasks into parallel batches.

How does test-driven development work in this implementation workflow?▼

Each task follows a red-green-refactor rhythm: write a failing test, confirm it fails, write minimal code to pass, then refactor. Non-TDD exceptions like CSS, config, migrations, and docs must be explicitly marked with a reason.

Can I resume implementation after clearing the conversation context?▼

Yes. The skill writes checkpoint artifacts and updates .beislid/checkpoints/latest.json. After a fresh session, say 'continue implementation' or 'continue from checkpoint' and it reloads the matching checkpoint as primary context.

When does the skill dispatch parallel subagents?▼

Parallel dispatch happens only for batches of three or more independent tasks, after workspace placement readiness is verified. Each mutating delegate gets a dedicated worktree and branch; otherwise the batch runs sequentially.

What happens if a task keeps failing during implementation?▼

If a task fails three times, execution stops and the approach is questioned rather than the implementation. Blocked dependencies are surfaced immediately, and plan changes require updating both the plan and the todo list.
