Create Review

Bootstrap the review pipeline and generate a paste-ready review prompt for any AI reviewer.

Step 1: Determine the reviewer and session

Reviewer: If the user provided $ARGUMENTS, sanitize it to a safe kebab-case string (lowercase, strip any characters that aren't alphanumeric or hyphens, collapse multiple hyphens) and use that as the reviewer name (e.g. codex, gemini, gpt4, claude). If no argument, use generic.

Session: Detect from context:

1. If .chalk/reviews/ exists, check for the most recent session directory
2. Otherwise, infer from the current branch name (kebab-case)
3. If on main/master, ask the user

Store as {reviewer} and {session}.

Step 2: Bootstrap the review pipeline

Check if .chalk/reviews/scripts/pack.sh exists. If not, bootstrap the full pipeline:

mkdir -p .chalk/reviews/scripts .chalk/reviews/templates .chalk/reviews/sessions

Create .chalk/reviews/scripts/pack.sh

This script generates a review context pack from git state:

#!/usr/bin/env bash
set -euo pipefail

BASE_REF="${1:-origin/main}"
SESSION="${2:-adhoc}"
OUTPUT_PATH="${3:-.chalk/reviews/sessions/${SESSION}/pack.md}"

# Resolve base ref
if ! git rev-parse --verify "$BASE_REF" >/dev/null 2>&1; then
  for candidate in main origin/main master origin/master; do
    if git rev-parse --verify "$candidate" >/dev/null 2>&1; then
      BASE_REF="$candidate"
      break
    fi
  done
fi

MERGE_BASE="$(git merge-base HEAD "$BASE_REF" 2>/dev/null || echo "")"
if [ -z "$MERGE_BASE" ]; then
  MERGE_BASE="$(git rev-list --max-parents=0 HEAD | tail -n 1)"
fi

mkdir -p "$(dirname "$OUTPUT_PATH")"

{
  echo "# Review Pack"
  echo
  echo "- Session: \`$SESSION\`"
  echo "- Generated: $(date -u +"%Y-%m-%d %H:%M:%S UTC")"
  echo "- Base ref: \`$BASE_REF\`"
  echo "- Merge base: \`${MERGE_BASE:0:12}\`"
  echo "- Head: \`$(git rev-parse --short HEAD)\`"
  echo
  echo "## Diff Stat"
  echo '```'
  git diff --stat "$MERGE_BASE"..HEAD 2>/dev/null || echo "(no committed diff)"
  echo '```'
  echo
  echo "## Changed Files"
  CHANGED="$(git diff --name-only "$MERGE_BASE"..HEAD 2>/dev/null || true)"
  if [ -n "$CHANGED" ]; then
    echo "$CHANGED" | while IFS= read -r f; do [ -n "$f" ] && echo "- $f"; done
  else
    echo "- (none)"
  fi
  echo
  echo "## Commit Log"
  echo '```'
  git log --oneline "$MERGE_BASE"..HEAD 2>/dev/null || echo "(no commits ahead of base)"
  echo '```'
  echo
  echo "## Working Tree Status"
  echo '```'
  git status --short
  echo '```'
} > "$OUTPUT_PATH"

echo "PACK_PATH=$OUTPUT_PATH"

Create .chalk/reviews/scripts/render-prompt.sh

This script combines pack + handoff + reviewer template into a prompt:

#!/usr/bin/env bash
set -euo pipefail

REVIEWER="${1:?Usage: render-prompt.sh <reviewer> [pack-path] [handoff-path] [output-path]}"
PACK_PATH="${2:-}"
HANDOFF_PATH="${3:-}"
OUTPUT_PATH="${4:-}"
SESSION="${5:-}"
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"
ROOT_DIR="$(dirname "$SCRIPT_DIR")"

REVIEWER_TITLE="$(echo "$REVIEWER" | awk '{print toupper(substr($0,1,1)) substr($0,2)}')"

if [ -z "$SESSION" ] && [ -f "$ROOT_DIR/.current-session" ]; then
  SESSION="$(cat "$ROOT_DIR/.current-session")"
fi
SESSION="${SESSION:-adhoc}"

[ -z "$PACK_PATH" ] && PACK_PATH="$ROOT_DIR/sessions/$SESSION/pack.md"
[ -z "$HANDOFF_PATH" ] && HANDOFF_PATH="$ROOT_DIR/sessions/$SESSION/handoff.md"
[ -z "$OUTPUT_PATH" ] && OUTPUT_PATH="$ROOT_DIR/sessions/$SESSION/${REVIEWER}.prompt.md"

if [ ! -f "$PACK_PATH" ]; then
  echo "Pack not found at $PACK_PATH. Run pack.sh first." >&2
  exit 1
fi

mkdir -p "$(dirname "$OUTPUT_PATH")"

{
  echo "# $REVIEWER_TITLE Review Request"
  echo

  # Use the universal reviewer template
  TEMPLATE="$ROOT_DIR/templates/reviewer.template.md"
  if [ -f "$TEMPLATE" ]; then
    cat "$TEMPLATE"
  fi

  echo
  echo "---"
  echo
  echo "## Review Pack"
  cat "$PACK_PATH"

  if [ -f "$HANDOFF_PATH" ]; then
    echo
    echo "---"
    echo
    echo "## Handoff"
    cat "$HANDOFF_PATH"
  fi
} > "$OUTPUT_PATH"

echo "PROMPT_PATH=$OUTPUT_PATH"

Create .chalk/reviews/scripts/copy-prompt.sh

#!/usr/bin/env bash
set -euo pipefail

REVIEWER="${1:?Usage: copy-prompt.sh <reviewer> [pack] [handoff] [output] [session]}"
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"

OUTPUT="$(bash "$SCRIPT_DIR/render-prompt.sh" "$@")"
echo "$OUTPUT"

PROMPT_PATH="$(echo "$OUTPUT" | sed -n 's/^PROMPT_PATH=//p' | head -1)"
if [ -z "$PROMPT_PATH" ] || [ ! -f "$PROMPT_PATH" ]; then
  echo "Could not resolve prompt path." >&2
  exit 1
fi

COPIED=0
if command -v pbcopy >/dev/null 2>&1; then
  pbcopy < "$PROMPT_PATH" && COPIED=1 && echo "CLIPBOARD=pbcopy"
elif command -v xclip >/dev/null 2>&1; then
  xclip -selection clipboard < "$PROMPT_PATH" && COPIED=1 && echo "CLIPBOARD=xclip"
elif command -v wl-copy >/dev/null 2>&1; then
  wl-copy < "$PROMPT_PATH" && COPIED=1 && echo "CLIPBOARD=wl-copy"
fi

if [ "$COPIED" -eq 0 ]; then
  echo "CLIPBOARD=none (copy manually from $PROMPT_PATH)"
fi

Create .chalk/reviews/templates/reviewer.template.md

Only create if it does not already exist (preserve user customizations):

You are acting as an independent code reviewer.

Primary objective:
- Find real defects and risks in changed lines only.
- Prioritize actionable, high-signal output over style commentary.
- Report defects and risks, not style preferences.

Output format (required):

1. `## Verdict`
   - `Block merge: yes|no`
   - `Blocking findings: P0=<n>, P1=<n>`
   - If no P0/P1 findings, include exact text: `No blocking findings`.

2. `## Findings`
   - Use a markdown table with columns:
     - `ID` (R-001, R-002, ...)
     - `Severity` (P0 = critical | P1 = high | P2 = medium | P3 = low)
     - `Category` (Security | Correctness | Performance | Reliability | Testing)
     - `File:Line`
     - `Issue` — concise summary
     - `Failure mode` — what breaks and when
     - `Suggested fix` — actionable next step
     - `Confidence` (0.00–1.00)

3. `## Testing Gaps`
   - List missing tests that could hide regressions.

4. `## Open Questions`
   - Only unresolved assumptions that affect correctness.

Rules:
- Review changed lines only.
- Focus on correctness, security, reliability, and regression risk.
- Do not comment on formatting, import ordering, or trivial naming.
- Do not suggest broad refactors unless required for correctness.
- Keep recommendations patch-oriented and specific to the failure mode.
- If no blocking issues exist, explicitly state: `No blocking findings`.

Make scripts executable

chmod +x .chalk/reviews/scripts/pack.sh .chalk/reviews/scripts/render-prompt.sh .chalk/reviews/scripts/copy-prompt.sh

Create .chalk/reviews/PIPELINE.md

Write a brief usage guide explaining the pipeline, available scripts, and how to add custom reviewer templates. Refresh this on every run.

Step 3: Resolve the base branch

1. git merge-base main HEAD → if it works, use it
2. Try origin/main, then master, origin/master
3. Store as {base}

Step 4: Check for a handoff

Look for .chalk/reviews/sessions/{session}/handoff.md. If it exists, it will be included in the prompt. If not, warn the user that no handoff was found and suggest running /create-handoff first, but continue anyway.

Step 5: Generate the review pack

bash .chalk/reviews/scripts/pack.sh "{base}" "{session}" ".chalk/reviews/sessions/{session}/pack.md"

Step 6: Generate the review prompt

bash .chalk/reviews/scripts/render-prompt.sh "{reviewer}" \
  ".chalk/reviews/sessions/{session}/pack.md" \
  ".chalk/reviews/sessions/{session}/handoff.md" \
  ".chalk/reviews/sessions/{session}/{reviewer}.prompt.md" \
  "{session}"

Step 7: Copy to clipboard

bash .chalk/reviews/scripts/copy-prompt.sh "{reviewer}" \
  ".chalk/reviews/sessions/{session}/pack.md" \
  ".chalk/reviews/sessions/{session}/handoff.md" \
  ".chalk/reviews/sessions/{session}/{reviewer}.prompt.md" \
  "{session}"

Step 8: Report to the user

Show:

• The prompt file path
• Whether it was copied to clipboard
• Suggest: paste the prompt into any AI model (Codex, Gemini, GPT, Claude, etc.)
• To run multiple reviews: run the skill again with a different reviewer name for labeling (e.g. /create-review gemini)

Also mention:

• The reviewer template at .chalk/reviews/templates/reviewer.template.md can be customized
• Each run with a different reviewer name creates a separate prompt file in the session directory

Step 9: Save current session

Write the session name to .chalk/reviews/.current-session so subsequent runs can pick it up.

Rules

• Only create template files if they don't already exist — preserve user customizations
• Always refresh scripts (pack.sh, render-prompt.sh, copy-prompt.sh) to latest version
• Always refresh PIPELINE.md to latest version
• Do NOT modify any source code
• If no git changes exist ahead of base, warn the user but still generate (they may have local uncommitted work)
