technique-router — ZFC-Compliant PR Type Classification Skill
Purpose
Classifies a GitHub issue/PR description into a PR-type category, then recommends the appropriate autor technique. This is classification-only until routing is wired: classifyPrType() returns PR-type metadata, but technique resolution still happens separately through prompt/config defaults. All classification is delegated to the model API — no heuristic scoring, keyword matching, or hardcoded routing tables.
PR Types
| Type | Description |
|---|
state-bool | Widening boolean semantics (int 1/0, string '1'/'0' as valid True/False) |
data-norm | Normalizing key names and numeric formats (xp→xp_gained, NaN handling) |
ci-workflow | GitHub Actions workflow changes (YAML scripting, gate logic) |
typeddict-schema | TypedDict + validation for previously untyped data structures |
large-arch-refactor | Module extraction, moving functions between files |
unknown | Cannot determine from the description |
Technique Selection (Autor Research — Phase 10)
All 9 autor techniques converge within rubric noise (~80-85 confidence-interval overlap). SR-prtype is the safe default for all PR types. No per-type routing is statistically justified.
| Technique | Description | When to use |
|---|
SR-prtype | Self-Refine with PR-type classification | Safe default for all types |
SR-fewshot | Self-Refine with single prior PR exemplar | When a highly similar prior PR exists |
SR | Basic 3-round self-refine | Fallback |
ET | Extended chain-of-thought reasoning | Complex architectural decisions |
PRM | Process Reward Model (score each step) | Debugging, multi-step reasoning |
Usage
/technique-router <issue-title> <issue-body-or-url>
ZFC Compliance
This skill does NOT:
- Match keywords like "fix", "bug", "refactor" to determine type
- Use regex or substring checks for intent detection
- Apply hardcoded scoring weights
- Use if/else chains that guess intent from text
This skill DOES:
- Pass the issue text to the model with a clear classification prompt
- Return the model's classification as the decision
- Let the caller decide what to do based on the classification
Integration
Used by packages/core/src/decomposer.ts's classifyPrType() function in the AO core library. That function classifies PR type only; it does not yet select or apply a technique directly.
