Purpose

This Skill orchestrates parallel paper processing by splitting a paper into H1 sections and dispatching eligible Skills to subagents. In Phase 19 (current), it validates the proof-of-concept gate by running a single subagent on one section. Full parallel dispatch across all sections is Phase 20.

Trigger

Activates on: ppw:team [skill] [file] invocations.

Examples:

"ppw:team polish paper.tex" / "团队模式润色论文"
"ppw:team translation draft.md" / "并行翻译论文各章节"
"ppw:team de-ai paper.tex"

Modes

Mode	Default	Behavior
`guided`	Yes	split -> user confirms sections -> user selects PoC section -> run PoC -> user confirms quality
`direct`		skip confirmations, auto-select all body sections and first section for PoC

Mode inference: "直接" or "direct" in trigger switches to direct mode.

References

required: [] -- This Skill does not produce academic text itself. It orchestrates other Skills that load their own references at runtime. No reference files are needed by the orchestrator.

Ask Strategy

Guided mode -- three interaction points via AskUserQuestion:

Section selection (multiSelect) after splitting
PoC section selection (single select) from selected sections
PoC quality confirmation (approve/retry/exit)

Direct mode -- skip all three: auto-select all body sections (exclude preamble and bibliography), auto-select first body section for PoC, auto-approve PoC output.

Workflow

Step 0: Workflow Memory (Recording Only)

Skip pattern detection -- orchestrator is not suitable for auto-direct-mode recommendation.
Recording happens after Step 1 validation (see Step 1).

Step 1: Parse Arguments and Validate

Parse $ARGUMENTS to extract: Skill name (first word) and file path (remaining words).
Validate Skill name against whitelist: ["translation", "polish", "de-ai"]
If Skill is not in whitelist, reject with exact message: "[Skill] requires full-paper context and cannot run in parallel. Please run /ppw:[skill] directly."
Validate file exists and is .tex or .md format. If file not found or wrong format, report error and stop.
Read the paper file content.
Record workflow: Append {"skill": "ppw:team", "ts": "<ISO timestamp>"} to .planning/workflow-memory.json. Create file as [] if missing. Drop oldest entry if log length >= 50.

Step 2: Create Working Directory

Create .paper-team/ directory structure: sections/, output/.
If .paper-team/ already exists: in guided mode, ask to overwrite or cancel; in direct mode, overwrite silently.
Create backup of original paper: .paper-team/{filename}-backup-{YYYYMMDD-HHmm}.{ext} (timestamped to prevent overwrite on re-runs).
Initialize .paper-team/manifest.json:

{
  "version": "1.0",
  "created": "<ISO timestamp>",
  "source_file": "<original file path>",
  "source_format": "tex|md",
  "target_skill": "<skill name>",
  "sections": [],
  "poc": { "section_id": null, "status": "pending", "timestamp": null },
  "backup": "<backup filename>"
}

Step 3: Split Paper into Sections

For .tex files:

Preamble: everything from start through \begin{document} (inclusive). Label "00 - Preamble".
Bibliography: from \bibliography{} or \printbibliography through \end{document}. Label "99 - Bibliography".
Section boundaries: each \section command. Match \section followed by optional * and optional [...] then {...}. Ignore lines starting with % (LaTeX comments).
Content between \begin{document} and the first \section{} is "00 - Pre-section content" (if non-empty after trimming).
Each section: content from its \section{Title} line through the line before the next \section{ or the bibliography boundary.

For .md files:

Frontmatter: content before the first # heading. Label "00 - Frontmatter" (if non-empty).
Split at lines beginning with # (H1 headings).
Each H1 heading and its content until the next # is one section.

Section file naming: {NN}-{sanitized-title}.{ext} where NN = zero-padded sequence number, sanitized-title = title lowercased, spaces to hyphens, special chars removed, max 50 chars. Preamble: 00-preamble.{ext}. Pre-section: 00-presection.{ext}. Bibliography: 99-bibliography.{ext}. Frontmatter: 00-frontmatter.md.

Edge cases:

No \section{} commands: treat entire body as "01 - Full Body".
Only one section: warn parallel processing has no benefit; proceed with PoC anyway.
Empty section (no content between boundaries): skip, do not create file.

Write each section to .paper-team/sections/{filename}. Update manifest.json sections array with { "id": "NN", "title": "...", "file": "sections/filename", "selected": false, "status": "pending" } for each section.

Step 4: Section Selection

Guided mode: Present all detected sections via AskUserQuestion multiSelect:

AskUserQuestion({
  question: "Select sections to process with ppw:{skill}:\n选择要用 ppw:{skill} 处理的章节：",
  multiSelect: true,
  options: [
    { label: "NN - Title", description: "brief description or first line" }
  ]
})

Update manifest.json to set selected: true for chosen sections.

Direct mode: Auto-select all sections EXCEPT those with id "00" (preamble/presection/frontmatter) and "99" (bibliography). Update manifest accordingly. Display selected sections to user.

Step 5: PoC Section Selection

Guided mode: Present selected sections via AskUserQuestion (single select):

AskUserQuestion({
  question: "Select one section for proof-of-concept test:\n选择一个章节进行概念验证测试：",
  options: [
    { label: "NN - Title", description: "will be processed by a subagent" }
  ]
})

Direct mode: Auto-select the first selected section (lowest NN number among selected).

Step 6: PoC Gate Execution

Read the target Skill's SKILL.md from .claude/skills/ppw-{skill}/SKILL.md. If not found, report error: "Skill ppw:{skill} not found at .claude/skills/ppw-{skill}/SKILL.md" and stop.
Read the selected section file from .paper-team/sections/{file}.
Construct the subagent prompt (use this template verbatim, filling in placeholders):

You are executing a paper section processing task in direct mode.

## Skill Instructions

{FULL CONTENT OF TARGET SKILL.MD INSERTED HERE}

## Task

Process the following paper section file using the Skill instructions above.

- Input file: .paper-team/sections/{section-filename}
- Mode: direct (skip all AskUserQuestion calls, skip Workflow Memory Step 0)
- Write output to: .paper-team/output/{section-filename}
- Do NOT ask the user any questions. Proceed with defaults.
- Load all required references as specified in the Skill instructions.
- Produce output as if you were running the Skill directly on this section.
- If the Skill normally edits in-place, instead write the processed output to the output path above.

Spawn a single subagent via the Agent tool with this prompt.
Wait for subagent completion.
Update manifest.json: set poc.section_id, poc.status to "completed", poc.timestamp to current ISO timestamp. Set the section's status to "completed".

Step 7: PoC Quality Confirmation

Guided mode: Read the subagent output from .paper-team/output/{file}. Display a brief excerpt (first 20-30 lines) to the user. Then ask:

AskUserQuestion({
  question: "PoC gate: Is the subagent output quality acceptable?\n概念验证：子代理输出质量是否可接受？",
  options: [
    { label: "Approved - PoC gate passed", description: "Quality is comparable to main-session execution" },
    { label: "Retry", description: "Re-run PoC on the same section" },
    { label: "Exit", description: "Stop orchestration, quality is not acceptable" }
  ]
})

Approved: Update manifest.json poc.status to "passed". Display: "PoC gate passed. The ppw:team orchestrator is validated. To process all sections in parallel, use Phase 20's parallel dispatch (coming soon)."
Retry: Go back to Step 6. Loop at most 3 times, then suggest Exit.
Exit: Update manifest.json poc.status to "failed". Display message and suggest running the Skill directly: "/ppw:{skill} {file}"

Direct mode: Auto-approve (set poc.status to "passed"), display the first 10 lines of output and the success message.

Output Contract

Output	Format	Condition
`section_files`	Individual files in `.paper-team/sections/`	Always produced after Step 3
`manifest`	`.paper-team/manifest.json`	Always produced, updated throughout workflow
`poc_output`	Single file in `.paper-team/output/`	Produced after Step 6

Edge Cases

Situation	Handling
Paper has no `\section{}` commands	Treat entire body as one section "01 - Full Body"
Paper has only one section	Warn parallel processing has no benefit; proceed with PoC
File path has spaces	Quote file paths in all Read/Write operations
`.paper-team/` already exists	Ask to overwrite or cancel (guided) / overwrite silently (direct)
Subagent fails or times out	Report error, suggest retry or exit
`\section*{}` (unnumbered)	Match as section boundary (pattern includes optional `*`)
`\section[short]{long}` (optional arg)	Match as section boundary (pattern includes optional `[...]`)
Empty section (no content between boundaries)	Skip empty sections, do not create files

Fallbacks

Scenario	Fallback
Structured Interaction unavailable	Ask plain-text questions for section selection
Agent tool fails	Report error; suggest running Skill directly on the section
Target Skill SKILL.md not found	Report: "Skill ppw:{skill} not found at .claude/skills/ppw-{skill}/SKILL.md"
`.planning/workflow-memory.json` missing	Create as `[]` before appending
