subsection-writer（小节作者）

Subsection Writer (compatibility router)

Purpose: write or refine per-section survey prose under sections/ while keeping the current pipeline contract unchanged.

Compatibility mode:

• output paths stay the same
• scripts/run.py still handles approval checks, missing-file bootstrap, and sections/sections_manifest.jsonl
• writing guidance now lives in references/ instead of being encoded primarily in the script

Load Order

Always read:

• references/overview.md
• references/paragraph_jobs.md
• references/paragraph_job_archetypes.md when adjusting paragraph-role behavior or refactoring writer policy out of Python
• references/bootstrap_assembly.md when reasoning about compatibility-mode bootstrap behavior

Read as needed:

• references/opener_catalog.md when paragraph 1 sounds generic or narrated
• references/contrast_moves.md when building A-vs-B comparison paragraphs
• references/eval_anchor_patterns.md when making performance / robustness / benchmark claims
• references/limitation_moves.md when adding caveats or local conclusions
• references/examples_good.md and references/examples_bad.md for calibration only

Machine-readable contract:

• assets/subsection_writer_context.schema.json
• assets/bootstrap_paragraph_templates.json
• assets/paragraph_job_templates.json

Inputs

Required:

• DECISIONS.md (must include Approve C2)
• outline/outline.yml
• outline/writer_context_packs.jsonl (preferred)
• citations/ref.bib

Optional but useful:

• outline/subsection_briefs.jsonl
• outline/evidence_drafts.jsonl
• outline/evidence_bindings.jsonl
• outline/anchor_sheet.jsonl
• outline/chapter_briefs.jsonl

Outputs

Keep the current contract:

• sections/abstract.md
• sections/discussion.md
• sections/conclusion.md
• sections/S<sec_id>.md for H2-without-H3 bodies
• sections/S<sec_id>_lead.md for H2 lead blocks
• sections/S<sub_id>.md for H3 bodies
• sections/sections_manifest.jsonl

Writer policy

The active rule is move coverage, not paragraph quota. A subsection should cover the necessary argument moves the pack supports; do not pad to a fixed count when the evidence does not justify it.

Opener / ending policy:

• generate 2-4 opener candidates from the pack's actual tension, contrast, protocol, or limitation signals; keep the most content-bearing option instead of reusing one stock stem everywhere
• let subsection endings emerge from evidence-bearing comparison / limitation material; do not append a fixed “safest synthesis / decision rule” closer just to make the paragraph feel finished
• normalize internal axis labels into natural reader prose; slash-style brief handles should remain planning metadata, not leak unchanged into the paper

Script boundary

Use scripts/run.py as a helper only:

• it may bootstrap missing H3 files and refresh the manifest
• it must not be treated as the canonical source of prose shape or voice policy

Quick Start

• python.codex/skills/subsection-writer/scripts/run.py --workspace workspaces/<ws>

Troubleshooting

• If the pack is thin, stop and route upstream instead of padding prose.
• If the subsection sounds narrated, reload references/opener_catalog.md and references/examples_bad.md.
• If a claim lacks protocol context, reload references/eval_anchor_patterns.md before rewriting.

Execution notes

When running in compatibility mode, scripts/run.py currently consumes:

• DECISIONS.md for Approve C2
• outline/outline.yml to enumerate chapter / subsection files
• outline/writer_context_packs.jsonl as the primary drafting input
• citations/ref.bib for in-scope citations
• outline/subsection_briefs.jsonl, outline/evidence_drafts.jsonl, outline/evidence_bindings.jsonl, outline/anchor_sheet.jsonl, and outline/chapter_briefs.jsonl as optional enrichment sources

Script

Quick Start

• python.codex/skills/subsection-writer/scripts/run.py --workspace <workspace_dir>

All Options

• --workspace <dir>
• --unit-id <id>
• --inputs <a;b;...>
• --outputs <a;b;...>
• --checkpoint <C*>

Examples

• python.codex/skills/subsection-writer/scripts/run.py --workspace workspaces/<ws>

Troubleshooting

• If DECISIONS.md lacks Approve C2, stop and fix approval first.
• If outline/writer_context_packs.jsonl is thin, reroute upstream instead of padding prose.
• If citation scope looks wrong, re-check citations/ref.bib and the writer packs before editing output text.
