Skill Slide Critic

Slide Critic Skill

Interactive critique feedback loop for academic presentations. Delegates to slide-critic-agent for initial material review, parses the structured critique report, presents findings to the user grouped by severity tier, collects accept/reject/modify decisions, loops until all issues are addressed, and produces a final filtered critique report consumable by /plan.

IMPORTANT: This skill implements the skill-internal postflight pattern. After the subagent returns and the interactive loop completes, this skill handles all postflight operations (status update, artifact linking, git commit) before returning.

Context References

Reference (do not load eagerly):

• Path: .opencode/context/formats/return-metadata-file.md - Metadata file schema
• Path: .opencode/context/patterns/postflight-control.md - Marker file protocol
• Path: .opencode/context/patterns/file-metadata-exchange.md - File I/O helpers
• Path: .opencode/context/patterns/jq-escaping-workarounds.md - jq escaping patterns (Issue #1132)

Note: This skill runs delegation then interactive Q&A. Context is loaded by the delegated agent.

Trigger Conditions

This skill activates when:

• /critique command with task number input
• /research on a task with task_type: "present:slides" and workflow_type: "slides_critique"
• Present extension is available
• Task has existing slide materials to review (research reports, plans, or assembled slides)

Input Parameters

Required Parameters

• task_number - Task number (must exist in state.json with task_type containing "slides")
• session_id - Session ID from orchestrator

Optional Parameters

• focus_categories - Subset of 6 rubric categories to prioritize (e.g., ["Narrative Flow", "Timing Balance"])
• audience_context - Audience description for calibrating review
• materials_to_review - Override default material discovery (array of file paths)

Execution Flow

Stage 1: Input Validation

Validate required inputs:

• task_number - Must be provided and exist in state.json
• Verify task_type contains "slides" (supports "present:slides", "slides")

# Lookup task
task_data=$(jq -r --argjson num "$task_number" \
  '.active_projects[] | select(.project_number == $num)' \
  specs/state.json)

# Validate exists
if [ -z "$task_data" ]; then
  return error "Task $task_number not found"
fi

# Extract fields
task_type=$(echo "$task_data" | jq -r '.task_type // ""')
status=$(echo "$task_data" | jq -r '.status')
project_name=$(echo "$task_data" | jq -r '.project_name')
description=$(echo "$task_data" | jq -r '.description // ""')
forcing_data=$(echo "$task_data" | jq -r '.forcing_data // {}')

# Validate task_type (supports "present:slides" or legacy "slides")
if [ "$task_type" != "present:slides" ] && [ "$task_type" != "slides" ]; then
  return error "Task $task_number is not a slides task (task_type=$task_type)"
fi

# Extract talk_type from forcing_data
talk_type=$(echo "$forcing_data" | jq -r '.talk_type // "CONFERENCE"')

Stage 2: Preflight Status Update

Update task status to researching BEFORE invoking subagent.

padded_num=$(printf "%03d" "$task_number")
task_dir="specs/${padded_num}_${project_name}"
mkdir -p "$task_dir"

# Update state.json
jq --arg ts "$(date -u +%Y-%m-%dT%H:%M:%SZ)" \
   --arg sid "$session_id" \
  '(.active_projects[] | select(.project_number == '$task_number')) |= . + {
    status: "researching",
    last_updated: $ts,
    session_id: $sid
  }' specs/state.json > specs/tmp/state.json && mv specs/tmp/state.json specs/state.json

# Update TODO.md marker to [RESEARCHING]

Create postflight marker:

cat > "${task_dir}/.postflight-pending" << EOF
{
  "session_id": "${session_id}",
  "skill": "skill-slide-critic",
  "task_number": ${task_number},
  "operation": "slides_critique",
  "reason": "Postflight pending: status update, artifact linking, git commit",
  "created": "$(date -u +%Y-%m-%dT%H:%M:%SZ)",
  "stop_hook_active": false
}
EOF

Stage 3: Prepare Delegation Context

Discover materials to review (if not provided via materials_to_review):

# Auto-discover materials in task directory
report_files=$(ls -1 "${task_dir}/reports/"*.md 2>/dev/null)
plan_files=$(ls -1 "${task_dir}/plans/"*.md 2>/dev/null)

# Check for assembled slides
talk_dir="talks/${task_number}_${project_name}"
slide_files=$(ls -1 "${talk_dir}/slides.md" 2>/dev/null)

Build the materials array from discovered files, or use the materials_to_review parameter if provided.

Delegation context:

{
  "session_id": "{session_id}",
  "delegation_depth": 1,
  "delegation_path": ["orchestrator", "critique", "skill-slide-critic", "slide-critic-agent"],
  "timeout": 3600,
  "task_context": {
    "task_number": N,
    "task_name": "{project_name}",
    "description": "{description}",
    "task_type": "present:slides"
  },
  "workflow_type": "slides_critique",
  "forcing_data": {
    "talk_type": "{talk_type}",
    "materials_to_review": ["{discovered or provided paths}"],
    "focus_categories": "{focus_categories or omitted}",
    "audience_context": "{audience_context or omitted}"
  },
  "metadata_file_path": "specs/{NNN}_{SLUG}/.return-meta.json"
}

Stage 4: Invoke Subagent

CRITICAL: Use the Task tool to spawn the slide-critic-agent. Do NOT use Skill(...).

Tool: Task (NOT Skill)
Parameters:
  - subagent_type: "slide-critic-agent"
  - prompt: [Include full delegation context from Stage 3]
  - description: "Critique presentation materials for task {N}"

The slide-critic-agent will:

1. Load the critique rubric and priority matrix
2. Read all review materials
3. Evaluate against 6 rubric categories (or focus_categories)
4. Write a critique report to specs/{NNN}_{SLUG}/reports/{MM}_slide-critique.md
5. Write metadata to specs/{NNN}_{SLUG}/.return-meta.json

DO NOT use Skill(...) - this will FAIL. Always use Task.

Stage 4b: Self-Execution Fallback

CRITICAL: If you performed the work above WITHOUT using the Task tool (i.e., you read files, wrote artifacts, or updated metadata directly instead of spawning a subagent), you MUST write a .return-meta.json file now before proceeding. Use the schema from return-metadata-file.md with status researched.

If you DID use the Task tool, skip this stage -- the subagent already wrote the metadata.

Interactive Critique Loop (Stages 5-7)

Stage 5: Parse Critique Report

After the subagent returns, read the critique report and extract findings.

1. Read metadata file to get the critique report path:

   metadata_file="${task_dir}/.return-meta.json"
   meta_status=$(jq -r '.status' "$metadata_file")
   critique_report_path=$(jq -r '.artifacts[0].path // ""' "$metadata_file")
   findings_count=$(jq -r '.metadata.findings_count // {}' "$metadata_file")
   

2. If agent failed or no findings: Skip the interactive loop. Proceed directly to postflight with the agent's status.

3. Read the critique report and parse findings using these patterns:

   Per-slide heading: ### Slide N ({slide_type}) Finding line: - [{severity}] {category}: {description} Suggestion line: Suggested improvement: {text} (indented under finding) General heading: ### General (Cross-Cutting) Recommendation tiers: ### Must Fix, ### Should Fix, ### Nice to Fix

4. Build numbered issue list:

   issues = [
     { id: 1, slide: "Slide 3", severity: "Critical", category: "Narrative Flow",
       description: "...", suggestion: "...", tier: "Must Fix" },
     { id: 2, slide: "Slide 7", severity: "Critical", category: "Audience Alignment",
       description: "...", suggestion: "...", tier: "Must Fix" },
     { id: 3, slide: "General", severity: "Major", category: "Timing Balance",
       description: "...", suggestion: "...", tier: "Should Fix" },
     ...
   ]
   

   Assign tier based on severity:

   • Critical -> "Must Fix"
   • Major -> "Should Fix"
   • Minor -> "Nice to Fix"

5. If no findings found in report (agent found no issues): Report success with zero findings. Skip interactive loop.

Stage 6: Interactive Critique Loop

Present all findings grouped by severity tier in a single consolidated AskUserQuestion. Collect user decisions and loop until all issues are addressed or user exits.

AskUserQuestion format:

Critique findings for your {talk_type} presentation ({N} total issues):

=== MUST FIX ({count}) ===

 1. [Critical] {category} - {slide}: {description}
    Suggested: {suggestion}

 2. [Critical] {category} - {slide}: {description}
    Suggested: {suggestion}

=== SHOULD FIX ({count}) ===

 3. [Major] {category} - {slide}: {description}
    Suggested: {suggestion}

 4. [Major] {category} - {slide}: {description}
    Suggested: {suggestion}

=== NICE TO FIX ({count}) ===

 5. [Minor] {category} - {slide}: {description}
    Suggested: {suggestion}

---
For each issue, respond with its number and action:
  1: A          (accept as-is)
  3: R          (reject/dismiss)
  5: M add comparison to Smith 2024  (modify the suggestion)

Shortcuts: "accept all", "reject all minor", "done" (accept remaining)

Response parsing grammar:

Parse user response line by line. Each line matches one of:

Track decisions per issue:

decisions = {
  1: { action: "accepted", modification: null },
  3: { action: "rejected", modification: null },
  5: { action: "modified", modification: "add comparison to Smith 2024" },
  ...
}

Loop continuation:

After processing responses:

• If all issues are addressed (each has an accepted/rejected/modified decision): proceed to Stage 7
• If unaddressed issues remain AND user did not say "done": re-present ONLY unaddressed issues in a follow-up AskUserQuestion
• Maximum 3 loop iterations to prevent infinite cycles. After 3 iterations, auto-accept all remaining unaddressed issues.

Stage 7: Generate Filtered Critique Report

Write the final filtered report incorporating user decisions.

Determine artifact number:

next_num=$(jq -r --argjson num "$task_number" \
  '.active_projects[] | select(.project_number == $num) | .next_artifact_number // 2' \
  specs/state.json)
# Use next available number for the filtered report
filtered_num=$(printf "%02d" "$next_num")

Write to specs/{NNN}_{SLUG}/reports/{MM}_filtered-critique.md:

# Filtered Critique Report: {title}

- **Task**: {N} - {description}
- **Talk Type**: {talk_type}
- **Original Findings**: {total} ({critical} critical, {major} major, {minor} minor)
- **Accepted**: {accepted_count} ({modified_count} with modifications)
- **Rejected**: {rejected_count}

## Accepted Issues

### Must Fix ({count})

- Slide {N}: [{severity}] {category}: {description}
  Suggested: {original suggestion}
  {If modified: "User modification: {user text}"}

### Should Fix ({count})

- Slide {N}: [{severity}] {category}: {description}
  Suggested: {original suggestion}

### Nice to Fix ({count})

- Slide {N}: [{severity}] {category}: {description}
  Suggested: {original suggestion}

## Rejected Issues ({count})

{Listed for reference but marked as dismissed}

- Slide {N}: [{severity}] {category}: {description} -- DISMISSED

## User Notes

{Any freeform feedback captured during the loop, or "None"}

## Source Critique Report

Original critique: {critique_report_path}

Update .return-meta.json with final artifact info:

{
  "status": "researched",
  "artifacts": [
    {
      "type": "report",
      "path": "specs/{NNN}_{SLUG}/reports/{MM}_filtered-critique.md",
      "summary": "Filtered critique: {accepted_count} accepted, {rejected_count} rejected of {total} findings"
    }
  ],
  "metadata": {
    "findings_count": {
      "total": N,
      "accepted": N,
      "rejected": N,
      "modified": N
    }
  }
}

Postflight (ALWAYS EXECUTE)

The following stages MUST execute after work is complete, whether the work was done by a subagent or inline. Do NOT skip these stages for any reason.

Stage 8: Read Metadata File

metadata_file="${task_dir}/.return-meta.json"

if [ -f "$metadata_file" ] && jq empty "$metadata_file" 2>/dev/null; then
    meta_status=$(jq -r '.status' "$metadata_file")
    artifact_path=$(jq -r '.artifacts[0].path // ""' "$metadata_file")
    artifact_type=$(jq -r '.artifacts[0].type // ""' "$metadata_file")
    artifact_summary=$(jq -r '.artifacts[0].summary // ""' "$metadata_file")
else
    echo "Error: Invalid or missing metadata file"
    meta_status="failed"
fi

Stage 9: Update Task Status (Postflight)

Stage 10: Link Artifacts

Add artifact to state.json with summary. Use the two-step jq pattern to avoid Issue #1132.

Update TODO.md: Link artifact per @.opencode/context/patterns/artifact-linking-todo.md with field_name=**Report**, next_field=**Description**.

Stage 11: Git Commit

git add -A
git commit -m "task ${task_number}: complete slide critique

Session: ${session_id}"

Stage 12: Cleanup

rm -f "${task_dir}/.postflight-pending"
rm -f "${task_dir}/.postflight-loop-guard"
rm -f "${task_dir}/.return-meta.json"

Stage 13: Return Brief Summary

Success:

Slide critique completed for task {N}:
- Evaluated materials against {category_count} rubric categories
- Talk type: {talk_type}
- Original findings: {critical} critical, {major} major, {minor} minor
- User decisions: {accepted} accepted ({modified} modified), {rejected} rejected
- Filtered report: specs/{NNN}_{SLUG}/reports/{MM}_filtered-critique.md
- Status updated to [RESEARCHED]
- Changes committed with session {session_id}

No findings:

Slide critique completed for task {N}:
- No issues found by slide-critic-agent
- Materials appear well-structured for {talk_type} presentation
- Status updated to [RESEARCHED]
- Changes committed with session {session_id}

Partial:

Slide critique partially completed for task {N}:
- Agent produced findings but interactive loop was interrupted
- Run critique again to resume (existing report preserved)

Error Handling

Task not found

Slide critique error for task {N}:
- Task not found in state.json
- No status changes made

Wrong task type

Slide critique error for task {N}:
- Task is not a slides task (task_type={task_type})
- No status changes made

Metadata file missing after agent

Keep status at preflight level (researching) for resume.

No findings from agent

Not an error. Report "no issues found" as success. Skip interactive loop. Write researched status.

User abandons mid-loop

Accept all remaining unaddressed issues. Proceed to filtered report generation. Note in report that some issues were auto-accepted due to early exit.

Git commit failure

Non-blocking. Log failure but continue.

Return Format

This skill returns a brief text summary (NOT JSON). The JSON metadata is written to the file and processed internally.
