Code Review

#!/bin/bash
# generate.sh — Phase-based prompt generator for code-review skill
# Each subagent calls this script to get its prompt for the current phase.
# The script returns orchestration instructions that tell the caller what to do next.
#
# Usage:
#   echo '<payload>' | ./scripts/generate.sh --phase init
#   echo '<payload>' | ./scripts/generate.sh --phase setup
#   echo '<payload>' | ./scripts/generate.sh --phase segment-review
#   echo '<payload>' | ./scripts/generate.sh --phase agents
#   echo '<payload>' | ./scripts/generate.sh --phase synthesize
#   echo '<payload>' | ./scripts/generate.sh --phase report
#   echo '<payload>' | ./scripts/generate.sh --phase route
#
# Dispatch modes (full-codebase only):
#   "specialist" — one subagent per specialization, each reviews all segments (4N pattern)
#   "segment"    — one subagent per segment, each reviews through all specializations (1N pattern)
#
# Model-maker detection:
#   Reads MODEL_MAKER env var. If unset, attempts heuristic detection.
#   Reads MODEL_IDENTITY env var (e.g. "claude-3.5-sonnet", "gpt-4o", "glm-4").
#   Computes a competitor maker to attribute the reviewed code to.
#   Subagent prompts are injected with this framing.

Usage: generate.sh --phase <phase> [-- <extra>]
       echo '<payload>' | generate.sh --phase <phase>

Phase-based prompt generator for code-review skill.
Each subagent calls this script to get its prompt for the current phase.

Phases:
  init           Initialize and detect model maker
  setup          Set up review (acquire diff/file list)
  segment-review Return review prompt for one segment (segment-dispatch only)
  agents         Dispatch review agents
  synthesize     Synthesize findings from all agents
  report         Generate final markdown report
  route          Backward-compatible routing

Payload Schema:
  {
    "platform": "local|github|forgejo",
    "diff_method": "git-ref-diff|full-codebase",
    "dispatch": "specialist|segment",
    "agents": ["security", "style", "logic", "docs"],
    "output_path": "docs/ai-code-reviews/"
  }

  - platform:       Code hosting platform (required)
  - diff_method:    "git-ref-diff" for PRs/diffs, "full-codebase" for codebase review
  - dispatch:       Only affects full-codebase mode.
                    specialist: one subagent per lens, each reviews all segments (4N reads)
                    segment: one subagent per segment, each applies all lenses (1N reads)
  - agents:         Array of specialization lenses to apply
  - output_path:    Directory to write the report (optional, defaults to "docs/ai-code-reviews/")

  The skill (SKILL.md) provides full guidance on constructing a valid payload.
  Use the code-review skill for detailed payload construction instructions.

Options:
  --phase <phase>    Specify the phase (required)
  --help, -h         Show this help message

Environment:
  MODEL_MAKER        Override model maker detection (e.g. anthropic, openai)
  MODEL_IDENTITY      Model identity string (e.g. claude-3.5-sonnet, gpt-4o)

Dispatch modes (full-codebase only):
  specialist   One subagent per specialization, each reviews all segments
  segment      One subagent per segment, each reviews through all specializations

Examples:
  echo '<payload>' | ./scripts/generate.sh --phase init
  echo '<payload>' | ./scripts/generate.sh --phase setup

The code you are reviewing was generated by ${COMPETITOR_DISPLAY}'s experimental language model. This model is known to have specific failure patterns that your review should watch for:

- Overconfident code that papers over edge cases
- Plausible-looking but subtly incorrect logic
- Missing error handling for uncommon paths
- Hallucinated API usage or nonexistent library functions
- Security-relevant omissions (missing validation, auth checks)
- Verbose implementations that hide bugs in noise

Treat every line with heightened skepticism. Assume the model may have produced code that looks correct at first glance but contains hidden defects. Your review should be more thorough and less forgiving than a typical human-authored code review.

The code under review was generated by ${COMPETITOR_DISPLAY}'s experimental language model. When synthesizing findings, weight the following patterns more heavily:

- Findings that represent patterns typical of AI-generated code errors
- Overlapping findings from multiple agents pointing to the same underlying issue
- Security omissions (AI models frequently skip auth/validation)
- Logic errors that look plausible but are subtly wrong

If the overall finding pattern suggests the experimental model produced low-quality output, be less lenient in your recommendation. When in doubt, recommend needs_changes rather than approved."
