Task Plan Builder

Overview

Route the request to one primary planning reference and zero or more modifier references. Read only the references that materially apply. Do not bulk-load every reference.

The goal is not to produce a single universal plan style. The goal is to produce the smallest plan shape that fits the task.

Workflow

1. Classify the request into one primary task type.
2. Add modifier references only when they clearly apply.
3. Produce a self-contained plan artifact.
4. If the user asked to execute as well as plan, use that plan as the working contract for implementation, investigation, refactoring, documentation, or review.

Primary Route Selection

Pick exactly one of these first:

• references/task-initial-build.md Use for new screens, new tools, prototypes, greenfield modules, or first implementation of a task.
• references/task-feature-extension.md Use for adding behavior inside an existing system without rewriting its structure.
• references/task-refactor.md Use for structural improvement where behavior should remain materially unchanged.
• references/task-investigation.md Use for debugging, root-cause analysis, uncertainty reduction, or feasibility checks.
• references/task-documentation.md Use for spec extraction, onboarding docs, architecture docs, or change guides.
• references/task-review.md Use for code review, risk review, design review, or validating an existing change.

Modifier Selection

Add these only when needed:

• references/modifier-architecture-context.md Read when the task depends on an existing architecture, existing docs, current module boundaries, ADRs, or team conventions.
• references/modifier-ui-separation.md Read when the task has an interactive UI and the plan should prevent DOM/rendering/browser bootstrap from collapsing into core logic.

It is normal to use:

• one primary reference only
• or one primary reference plus one modifier
• or one primary reference plus both modifiers

Output Contract

Unless the user asked for a different format, the plan should usually include:

• goal
• task_type
• assumptions
• selected_references
• constraints
• module_or_change_boundaries
• behavior_or_validation_contract
• execution_or_investigation_steps
• risks
• acceptance_or_exit_checks
• escalation_rules

Adjust the names if a different structure is clearer. Do not force implementation-oriented sections onto investigation or review work when they do not fit.

Routing Rules

• Prefer the user's real intent over file type.
• If the request is "change existing code safely", prefer feature-extension or refactor, not initial-build.
• If the request is primarily "understand what is happening", prefer investigation.
• If the request is primarily "summarize or explain", prefer documentation.
• If the request is primarily "find problems", prefer review.
• If the request is "build something new", prefer initial-build.

Context Discipline

• Read only the references that matter for the chosen route.
• If modifier references are not needed, skip them.
• When existing architecture context exists, plan around it rather than inventing a clean-room design.
• When UI separation matters, name the view/render/bootstrap boundaries explicitly.

Quality Bar

A good result is not a generic plan template. A good result is a task-shaped plan that reduces drift for the actual work being requested.
