name: dialectical-refinement description: Transform ambiguous specs into implementable work items through adversarial refinement. This skill should be used PROACTIVELY when receiving specs, claiming epics, or starting work on complex (l/xl) tasks. Use /breakdown for spec->tasks decomposition, /refine for sharpening individual items.

Dialectical Refinement

Overview

Surface hidden complexity before implementation through adversarial tension. A single reviewer tends toward over-engineering or over-simplification; opposing passes converge on correct scope.

When to Use (Proactive Triggers)

Trigger	Action
Receiving external spec/PRD	/breakdown <spec.md>
Claiming an epic	/refine then /breakdown
Starting l/xl complexity task	/refine <task-id>
Spec feels "clear but big"	Run refinement - hidden complexity likely

The 4-Pass Process

Pass 1: Formalize (Analyst)

Goal: Surface ambiguity.

• What terms are undefined?
• What's the input/output contract?
• What exists vs. genuinely new?
• What are acceptance criteria?
• What dependencies are implicit?

Output: Detailed spec with gaps called out.

Checkpoint: If significant unknowns remain (scope, architecture, must-have vs nice-to-have), ask 1-3 focused questions before proceeding.

HITL Clarification Protocol: When asking users, use AskUserQuestion with 2-4 concrete options and trade-offs (not open-ended). Structured questions prevent silent assumptions.

Pass 2: Simplify (Skeptic)

Goal: Cut to minimum viable.

• What can defer to future phase?
• What's nice-to-have vs essential?
• Can we hardcode now, parameterize later?
• What's the smallest valuable change?

Output: Dramatically reduced spec. Should feel "too minimal."

Pass 3: Challenge (Advocate)

Goal: Restore what was cut too aggressively.

• Did Pass 2 cut something essential?
• Are there cheap additions (small effort, high impact)?
• Will deferred items be much harder to add later?

Output: Restored scope where cuts went too far.

Pass 4: Synthesize (Judge)

Goal: Produce actionable spec.

• Resolve remaining debates
• Write concrete implementation details
• Define testable acceptance criteria
• Document OUT OF SCOPE explicitly

Quality Gate:

• GO - Ready to implement
• GO with caveats - Workable with listed risks
• REVISE - Too vague/large, needs another pass

Early Exit Rules

Not every spec needs 4 passes:

Complexity	Refinement
xs/s	Skip entirely
m	2-pass (Formalize -> Synthesize)
l/xl	Full 4-pass

If Pass 2 and Pass 3 produce nearly identical output, skip to Pass 4.

Complexity Estimation

Level	Description	Refinement?
xs	Trivial, obvious	No
s	Small, well-understood	No
m	Some unknowns	2-pass
l	Significant unknowns	4-pass
xl	Many unknowns	4-pass

Rule of thumb: If you can't describe implementation in 2-3 sentences, it's l or higher.

Command Reference

/refine <target>

Runs 4-pass refinement on a bead or spec file.

1. Reads target
2. Runs 4 sequential passes (separate agents for adversarial tension)
3. Presents synthesized spec
4. Updates bead, adds refined label

/breakdown <target>

Decomposes epic/spec into tasks.

1. Refines target first (if not already)
2. Proposes task breakdown with complexity estimates
3. Creates beads with dependencies and labels
4. Links tasks to parent epic

Breakdown Output Rules

Task Complexity	Label	Rationale
xs/s	refined	Obvious enough to implement
m/l/xl	needs-refinement	Review at claim time

Tasks get:

• parent-child dep to source epic
• blocks for sequential dependencies
• Complexity estimate
• Brief description (details filled at refinement)

Integration with bd

# Find work needing refinement
bd list --labels needs-refinement

# Find refined work ready to implement
bd ready --labels refined

# Find epics needing breakdown
bd list --type epic --labels needs-breakdown

Refined Spec Criteria

A spec is refined when:

1. Concrete - Files, functions, line estimates clear
2. Bounded - OUT OF SCOPE section exists
3. Testable - Acceptance criteria are observable
4. Sized - Complexity reflects actual uncertainty
5. Unblocked - Dependencies identified/tracked

Anti-Patterns

• Refinement theater - Running passes without meaningful changes
• Premature refinement - Refining backlog items that may never be done
• Skipping Pass 3 - Minimalism can go too far
• One-person dialectic - Use separate agents per pass for genuine tension

Why Separate Agents Per Pass

Each pass agent receives only previous output + goals, not internal reasoning. This prevents self-reinforcing mistakes. The Skeptic shouldn't remember why the Analyst included something - it should challenge from scratch.
