Papermill Init

Initialize a paper repository for use with papermill. Follow every step below in order. Be thorough in discovery but conservative in action -- never overwrite existing state.

---

Step 1: Check for Existing State

Check for state files in this order (Read tool):

1. .papermill/state.md (current format)
2. .papermill.md (legacy format — needs migration)

Case A: .papermill/state.md exists

Read it, display a summary (title, stage, format, authors), then offer refresh:

This repository is already initialized. Current state is shown above.

Would you like to refresh the state file? This will:

• Add any missing YAML fields from the current schema (preserving all existing data)
• Re-discover repo structure for new files or assets
• Ask about anything not yet captured (e.g., related papers)

Nothing will be overwritten or removed. Or use /papermill:status for a quick look.

If the user declines refresh, stop here. If they accept, proceed to Refresh Mode below.

Case B: .papermill.md exists (legacy)

Migrate to the new directory structure:

1. Create .papermill/ directory and .papermill/reviews/ subdirectory (Bash tool: mkdir -p .papermill/reviews)
2. Read .papermill.md content
3. Write it to .papermill/state.md (Write tool)
4. Delete .papermill.md (Bash tool: rm .papermill.md)
5. Tell the user:

Migrated state file. Moved .papermill.md → .papermill/state.md and created .papermill/reviews/ for review output. All existing data preserved.

Then display the summary and offer refresh as in Case A.

Case C: No state file found

Continue to Step 2 (fresh initialization).

---

Refresh Mode

Refresh is additive only -- it fills gaps without touching existing data. Run through each check below, report what was found, and apply changes only with user confirmation.

1. Schema migration

Compare the existing YAML frontmatter against the current schema (shown in Step 7). For each field in the schema that is missing from the file, add it with its default value. Common cases:

• Missing thesis block → add with empty claim, novelty, refined: null
• Missing prior_art block → add with empty defaults
• Missing experiments → add as []
• Missing venue block → add with target: null, candidates: []
• Missing review_history → add as []
• Missing related_papers → add as []
• Missing authors[].orcid → add as ""

Report what was added: "Added N missing fields to bring the state file up to the current schema." If nothing is missing, say so.

2. Re-discover repo structure

Run the same discovery as Step 2 (format detection, asset scan). Compare against what the state file already records. Report any new findings:

• New .bib files since initialization
• New code directories (research/, scripts/, etc.)
• Format change (e.g., repo now has .Rmd files but format says latex)

For format mismatches, ask the user: "The state file says latex but I also found .Rmd files. Should I update the format?" Only update with confirmation.

3. Fill in missing context

Check for content that the current init flow captures but older versions may not have asked about:

• Related papers (Step 6): If related_papers is empty or missing, run the repoindex discovery query (if repoindex is available) and present any papermill-tracked projects found. Also re-ask the Step 6 question about related work and software. If related_papers is already populated, still offer repoindex discovery to catch newly-initialized projects: "You have N related papers linked. Want me to check for any new papermill-tracked projects?"
• Related work and software (Step 6): If the Notes section does not contain a ## Related Work heading, run the related-work question from Step 6. If the user provides context, append it to the notes.
• Author ORCID: If authors[].orcid is empty, check deets and offer to fill it in.
• Title: If title is empty or looks like a placeholder, re-run title inference from Step 4.

4. Report and finish

Display what changed:

Refresh complete.

| Action | Details | |--------|---------| | Schema fields added | N (list them) | | New assets discovered | (list or "none") | | Context updated | (what was added or "nothing new") |

Append a timestamped note to the markdown body:

- YYYY-MM-DD (init refresh): Refreshed state file. [brief summary of changes].

Do NOT modify existing field values (stage, thesis, prior_art content, experiments, reviews, venue selections) unless the user explicitly asks. Those are managed by their respective skills.

---

Step 2: Discover Repository Structure

Search the repository to understand what kind of paper project this is (Glob tool). Look for all of the following and report what you find:

Format detection (check in this order)

1. LaTeX: Search for *.tex files (Glob tool). If found, set format: latex.
2. R Markdown: Search for *.Rmd files (Glob tool). If found, set format: rmarkdown.
3. Markdown: Search for paper.md, manuscript.md, or any markdown file that looks like a JOSS-style paper (contains title: in YAML frontmatter) (Glob/Grep tools). If found, set format: markdown.
4. If none of the above are found, ask the user what format they plan to use. Default to format: latex if they are unsure.

Additional assets

• *.bib files (bibliography)
• research/ or code/ or scripts/ or analysis/ directories (computational work)
• CITATION.cff (citation metadata)
• figures/ or img/ or images/ directories (graphics)
• Makefile, latexmkrc, or build configuration files
• README.md or CLAUDE.md (project documentation)

Report a brief inventory of what was found, for example:

Discovered structure:

• Format: latex (found paper/main.tex)
• Bibliography: paper/references.bib (12 entries)
• Research code: research/ directory present
• Figures: figures/ directory with 3 PDF files
• Build system: latexmk configuration found

---

Step 3: Get Author Information

Try to obtain the primary author's identity using the deets CLI tool, which manages personal metadata (Bash tool).

Run these commands (each may fail if deets is not installed -- that is fine):

deets get identity.name
deets get contact.email
deets get academic.orcid

• If deets is available and returns values: Use them as the primary author. Show the user what was found and ask for confirmation.
• If deets is not available or returns errors: Ask the user directly:

  I could not find author information via deets. Please provide:

  1. Your full name (as it appears on papers)
  2. Your email address
  3. Your ORCID (optional, e.g., 0000-0002-1234-5678)

Also check for author info in existing files (Read/Grep/Bash tools):

• \author{} blocks in .tex files
• CITATION.cff author fields
• Git config (git config user.name, git config user.email)

If multiple sources conflict, prefer: deets > tex file > CITATION.cff > git config. Always confirm with the user.

---

Step 4: Infer the Paper Title

Attempt to extract the title automatically (Grep/Read tools):

• LaTeX: Search for \title{...} in .tex files. Handle multiline titles and macro-containing titles.
• Markdown/R Markdown: Look for the first # heading or a title: field in YAML frontmatter.
• CITATION.cff: Check the title: field.

If a title is found, show it to the user and ask for confirmation. If no title is found, ask:

I could not detect a paper title. What is the working title for this paper?

---

Step 5: Infer the Current Stage

Determine the project stage based on what exists in the repository:

| Condition | Stage | |-----------|-------| | No paper content files exist (empty or new repo) | idea | | Only outline/notes exist, minimal prose | outlining | | Substantial paper content exists (multiple sections with prose) | drafting | | Paper appears complete with abstract, conclusion, references | review |

Use your judgment. When in doubt, default to drafting if paper content exists, or idea if the repo is new or nearly empty. Tell the user what stage you inferred and why.

---

Step 6: Ask About Related Work and Software

Ask the user whether this paper connects to any of their other projects or software:

Is this paper related to any of your other work? For example:

• Part of a series (e.g., "Part II of...")
• Builds on a foundation paper you wrote
• A companion covering a different angle of the same research
• Has an associated software package (CRAN, PyPI, GitHub, etc.)
• Uses results or software from another project

If so, briefly describe the relationships. If not, just say "standalone" and we'll move on.

This step is optional — if the user says "standalone" or skips it, proceed without adding anything. Do not press for detail.

If the user describes relationships or software, do two things:

1. Freeform notes: Note them verbatim for inclusion in the Notes section of .papermill/state.md (Step 7), under a ## Related Work and Software heading. This preserves context for Claude in future sessions.

2. Structured entries: For each relationship the user describes, create a related_papers entry. Ask the user to confirm for each:

   • The path to the related project (absolute or ~/-relative).
   • The relationship type (rel). Present the vocabulary and suggest the best fit:
     • extends / extended-by — builds on or is built upon
     • implements / implemented-by — theory ↔ software
     • companion — different angle on the same research
     • series — part of a numbered series
     • merged-into — absorbed into another paper
     • supersedes — replaces a previous version
   • A one-line label describing the relationship.

   Example interaction:

   You mentioned this paper extends the foundation paper in ~/github/papers/masked-causes-in-series-systems. I'll add:

   - path: ~/github/papers/masked-causes-in-series-systems
     rel: extends
     label: "Foundation paper — general masked-cause framework"
   

   Does that look right?

Repoindex discovery (opt-in)

After the manual question, check if repoindex is available (Bash tool: command -v repoindex). If it is:

1. Query for other papermill-tracked projects:

   repoindex sql "SELECT name, path FROM repos WHERE path IN (SELECT repo_path FROM files WHERE name = 'state.md' AND relative_path LIKE '.papermill/%')" --json
   

2. Filter out the current project from results.

3. If matches are found, present them:

   I found N other papermill-tracked projects via repoindex:

   | Project | Path | |---------|------| | masked-causes-in-series-systems | ~/github/papers/masked-causes-in-series-systems | | maskedcauses | ~/github/rlang/maskedcauses | | ... | ... |

   Are any of these related to this paper? If so, I'll add them to the related_papers block.

4. For each confirmed match, ask for rel type and label as above.

If repoindex is not available or the query fails, skip silently and proceed.

Repo-clue scanning

Also check for clues already in the repo (Read/Glob/Grep tools):

• CLAUDE.md, README.md for mentions of related papers or packages
• Bibliography for self-citations or references to sibling projects
• DESCRIPTION file (R package), setup.py/pyproject.toml (Python package), or package.json (Node) — these indicate associated software
• CITATION.cff for software DOIs

If any are found, mention them: "I noticed this repo contains a DESCRIPTION file for an R package called foo — is the paper about this package? I also see references to [X] in the bibliography — is that related work of yours?"

---

Step 7: Create .papermill/state.md

Create the .papermill/ directory structure and the state file.

1. Read the canonical schema (Read tool): ${CLAUDE_PLUGIN_ROOT}/docs/state-schema.md. This is the single source of truth for the state file structure, field constraints, and list field shapes.

2. Create the directory (Bash tool): mkdir -p .papermill/reviews

3. Write .papermill/state.md (Write tool) using the template from the schema doc. Populate placeholder values from earlier steps:

   • title from Step 4
   • stage from Step 5
   • format from Step 2
   • authors[0].{name, email, orcid} from Step 3
   • Leave the other structured fields at their empty defaults (they will be filled by thesis, prior-art, experiment, review, venue skills over time)

4. Append related-work context (if the user described related papers or software in Step 6): add a ## Related Work and Software section below the ## Notes section with the user's description in their own words. Preserve this verbatim; it is context for future Claude sessions.

---

Step 8: Report and Suggest Next Steps

After creating .papermill/state.md, display a summary:

Papermill initialized.

| Field | Value | |---------|--------------------| | Title | <title> | | Stage | <stage> | | Format | <format> | | Author | <name> (<email>) |

State file: .papermill/state.md

Then suggest the next skill based on the inferred stage:

| Stage | Suggestion | |-------|------------| | idea | "Run /papermill:thesis to develop your core claim and novelty statement." | | thesis | "Run /papermill:thesis to refine your thesis, or /papermill:prior-art to survey related work." | | literature | "Run /papermill:prior-art to survey related work and identify gaps." | | outlining | "Run /papermill:outline to structure your paper sections." | | drafting | "Run /papermill:thesis to articulate your core claim, or /papermill:status to review your progress." | | review | "Run /papermill:review to get feedback on your draft." | | submission | "Run /papermill:status to review submission readiness." |

Error Handling

• If the repository root cannot be determined, ask the user which directory to use.
• If file creation fails due to permissions, report the error clearly.
• Never silently skip steps. If any inference fails, ask the user explicitly.
• If the user interrupts or provides corrections during any step, incorporate them before proceeding.
