2478 Skills Standard Dea82938

Skill & Pipeline Standard (Codex CLI + Claude Code)

Core idea: Make pipelines that can "guide humans / guide models"—each skill is a semantic execution unit that knows what to do, how to do it, when it's done, and what NOT to do.

Design Principles

Traditional problem: Research pipelines are either black-box scripts (hard to debug) or loose documentation (requires human judgment at runtime).

Our solution: Skills-first + decomposed pipeline + evidence-first.

1. Semantic Skills: Each skill is not a function, but a guided execution unit:

   • inputs / outputs: explicit dependencies and artifacts
   • acceptance: completion criteria (e.g., "each subsection maps to >=8 papers")
   • notes: how to do it, edge cases, common mistakes
   • guardrail: what NOT to do (e.g., NO PROSE in C2-C4)

2. Decomposed Pipeline: 6 checkpoints (C0→C5), ~40+ atomic units (varies by pipeline; LaTeX adds a few), dependencies explicit in UNITS.csv

3. Evidence-First: C2-C4 enforce building evidence substrate first, C5 writes prose

Design Goals:

• Reusable: Same skill works across pipelines—no rewriting logic
• Guided: Newcomers/models follow acceptance + notes—no guessing
• Constrained: guardrail prevents executors from going off-rails
• Locatable: Failures point to specific skill + artifact—fix and resume

This repo is meant to work well across:

• OpenAI Codex (Codex CLI / IDE)
• Anthropic Claude Code (Claude Code CLI)

The goal is LLM-first semantic work + deterministic helper scripts, with a clear artifact contract (UNITS.csv) and explicit human checkpoints (DECISIONS.md).

0) Activation contract (skills-first UX)

This repo is meant to be driven by natural-language prompts (not “run this python command”).

Authoring rule of thumb:

• A user should be able to say one sentence (e.g., “给我写一个 agent 的 latex-survey”) and the agent can route to a pipeline, create a workspace, and start executing units.
• When you change a pipeline or add new skills, keep the “one-liner” prompts in README.md and SKILL_INDEX.md up to date.
• Default HITL: keep a single human approval checkpoint for survey-like pipelines (C2: scope+outline). If you add more checkpoints, justify why.

0b) Workspace contract (what must exist)

Workspaces should be auditable and self-contained. Standard artifacts:

• STATUS.md: current progress summary
• PIPELINE.lock.md: the selected pipeline (single source of truth)
• GOAL.md: topic/scope seed (used to draft queries + decisions)
• UNITS.csv: execution contract (unit deps + acceptance + status)
• CHECKPOINTS.md: checkpoint standards
• DECISIONS.md: human sign-offs (checkboxes like Approve C2)

1) Skill bundle contract (Anthropic-style)

Each skill is a folder under .codex/skills/<skill>/ and must include:

• SKILL.md (required): YAML front matter + operational instructions
• scripts/ (optional): deterministic helpers (scaffold/compile/validate)
• references/ (optional): deeper docs, checklists (avoid bloating SKILL.md)
• assets/ (optional): templates, schemas, fixtures

Progressive disclosure (recommended)

1. YAML front matter: only name + description (for discovery/routing).
2. SKILL.md body: the workflow + checklists + guardrails.
3. Scripts/resources: loaded only when the workflow calls for them.

Description field (routing-friendly)

To make discovery reliable across tools, prefer a multi-line description with explicit triggers and guardrails:

description: |
  <one-line summary>.
  **Trigger**: <keywords (EN/中文), comma-separated>.
  **Use when**: <when this skill is the right next step>.
  **Skip if**: <when not to use>.
  **Network**: <none|required|optional + offline fallback>.
  **Guardrail**: <NO PROSE / checkpoints / invariants>.

2) Script policy (deterministic helpers only)

Borrowing the best pattern from Anthropic’s skills repos:

• Scripts are treated as black-box helpers.
• Always run scripts with --help first (do not ingest source unless necessary).
• Scripts should be used for:
  • scaffolding (create directories/files/templates)
  • validation (format/schema checks)
  • compilation (LaTeX build, QA reports)
  • deterministic transforms (MD→LaTeX conversion, dedupe/ranking)

Authoring rule (skills-first):

• The primary workflow must be readable and executable from SKILL.md alone (LLM-first). If a script exists, treat it as optional validation/scaffolding, not the main instruction path.
• Avoid writing skills that require users to run python .../run.py as step 1; prefer “write/inspect artifacts” first, then offer scripts as an optional deterministic check.

Avoid scripts that “replace” semantic work (taxonomy/outline/notes/writing). If a script exists for those, it must be clearly labeled bootstrap only and the workflow must still require LLM refinement before marking a unit DONE.

2a) Role-based prompting (Anthropic-style, prompt-level guidance)

When a skill is semantic (structure, writing, editing), prefer role cards over “pipeline narration”.

Why:

• Role cards reduce ambiguity (“what am I trying to accomplish?”) without forcing templates (“how do I phrase it?”).
• They make skills composable: each skill owns one cognitive job and hands off a clean artifact.

Core roles (survey pipelines)

• Outline Architect (C2, 规划专家): designs a paper-like ToC (few, thick sections) and ensures every H3 is writeable (has a real comparison lens, not a topic bucket).
• Evidence Curator (C3/C4, 证据策展): turns papers/notes into contrastable evidence (claims, evaluation anchors, limitations) and exposes gaps early (so writing does not become padding).
• Section Author (C5, 小节内容专家): executes argument coverage (thesis + contrasts + protocol/evaluation anchoring + limitations) with in-scope citations; avoids “outline narration” and any fixed paragraph macro.
• Coherence Editor (C5, 章节衔接/结构编辑): connects sections (chapter leads, transitions) and removes generator voice without changing claims/citations.
• Consistency Reviewer (C5, 审稿视角/一致性审计): audits for scope drift, citation hygiene, and claim->evidence plausibility; routes upstream instead of “writing around” missing evidence.

Role card template (recommended in writing/structure skills)

Include a short ## Role cards section with 2–4 roles. Each role should state:

• Mission (one sentence)
• Do (2–4 bullets; concrete actions)
• Avoid (2–4 bullets; high-signal failure smells)

Guideline:

• Role cards should guide decisions and argument moves, not provide reusable sentence templates.

2b) Paper Voice Contract (writing-stage skills)

When a skill writes/edits prose (C5), prefer a "paper voice" contract over brittle style rules:

• No outline narration: avoid This subsection ..., In this subsection, we ..., Next, we move ... (rewrite as content claims + argument bridges).
• Evidence policy once: keep abstract/fulltext limitations in one short front-matter paragraph; don't repeat "abstract-only" disclaimers in every H3.
• Light signposting: avoid repeating a literal opener label across many subsections (e.g., Key takeaway:); vary opener phrasing and cadence.
• No count-based opener slots: avoid repeatedly starting sections with "Two limitations..." / "Three takeaways..." (reads templated); integrate caveats naturally or vary syntax.
• Soft academic tone: calm, understated; avoid hype (clearly, obviously, breakthrough) and "PPT speaker notes".
• Coherence without rigidity: use connectors (contrast/causal/extension) as needed, but don't force every paragraph to start with However/Moreover.
• Controlled citation scope: subsection-first by default; allow chapter-scoped reuse; treat bibkeys mapped to >= queries.md:global_citation_min_subsections subsections (A150++ default 4) as cross-cutting/global (allowed_bibkeys_global) to reduce brittle writer BLOCKED loops.

Generator voice anti-patterns (forbidden)

Planner talk (construction notes leaking into prose):

• ❌ "After X, Y makes the bridge explicit via..."
• ❌ "This paragraph turns the tension into a concrete comparison"
• ❌ "The following subsection synthesizes..."
• ✅ Instead: write the content directly (e.g., "Y addresses X by...")

Template stems (repetitive survey-guidance phrases):

• ❌ "Taken together, these approaches..." (limit ≤2 per draft)
• ❌ "This survey should..." (limit ≤1 per draft)
• ❌ "Two limitations..." / "The key point is that..." as repeated cross-section sentence slots
• ❌ "This run demonstrates..." (avoid entirely)
• ✅ Instead: vary synthesis openers (decision-first, tension-first, evidence-first)

Meta-guidance phrasing (talking about the paper instead of doing research):

• ❌ "We organize this section as follows..."
• ❌ "The remainder of this survey..."
• ❌ "Our contribution is to survey..."
• ✅ Instead: state findings/contrasts directly

Implementation bias:

• Prefer skill guidance + auditor warnings with examples over brittle hard blocks.
• Exception: the writer-selfloop section gate may treat a few generator-voice patterns as BLOCKING when they reliably correlate with hollow/templated prose (e.g., narration openers, slide navigation, repeated evidence-policy disclaimers). The fix is still a semantic rewrite (content claim + argument bridge), not code tweaks.

2c) "NO PROSE" Definition (C2-C4 guardrail)

C2-C4 outputs must be structured, non-narrative to prevent "middle-state leakage" where planning notes accidentally become final prose.

Allowed formats:

• ✅ Bullets, short phrases, JSONL fields, tables, schemas
• ✅ Structured keys (e.g., thesis, contrast_hook, paragraph_plan)
• ✅ Citation keys without narrative embedding (e.g., [@smith2023] in lists)

Forbidden patterns:

• ❌ Narrative paragraphs or prose sentences
• ❌ Semicolon-enumerated construction notes (e.g., "mechanism; data; evaluation")
• ❌ Meta-phrases about transformation (e.g., "turning X into Y", "bridging A to B")
• ❌ Template phrases (e.g., "Taken together", "This subsection will")
• ❌ Planner talk (e.g., "After establishing X, we move to Y")

18 skills enforce this: subsection-briefs, evidence-draft, evidence-binder, anchor-sheet, writer-context-pack, claim-matrix-rewriter, table-schema, chapter-briefs, transition-weaver (output only), and others in C2-C4.

Rationale: Intermediate artifacts are writing substrate, not drafts. Prose generation happens only in C5 after human approval.

2d) Refinement markers (*.refined.ok)

Some semantic artifacts are often bootstrapped by helper scripts (or generated quickly on first pass). In strict runs, we treat these as scaffolds until an explicit refinement marker exists.

Why:

• Prevents “bootstrap outputs” from silently passing into downstream writing (a major source of hollow/templated prose).
• Creates an auditable, low-friction signal that the artifact was actually reviewed/refined.
• Also doubles as a freeze marker so scripts don’t overwrite refined work.

How:

• After you manually refine an artifact and it passes the skill checklist, create an empty marker file next to it (same folder).
• The strict quality gate blocks until the marker exists (when the pipeline profile is arxiv-survey*).

Common markers for arxiv-survey*:

• outline/subsection_briefs.refined.ok
• outline/chapter_briefs.refined.ok
• outline/evidence_bindings.refined.ok
• outline/evidence_drafts.refined.ok
• outline/anchor_sheet.refined.ok
• outline/writer_context_packs.refined.ok

Guardrail:

• Do not create a refinement marker until the artifact is subsection-specific (no repeated tensions, no generic axis bundles) and contains no placeholders.

3) Pipeline/Units contract (repo-specific)

Single source of truth

• UNITS.csv is the execution contract (one row = one deliverable with acceptance criteria).
• pipelines/*.pipeline.md defines the pipeline intent and checkpoints, and points to the concrete templates/UNITS.*.csv.
• If a pipeline doc and its units template diverge, the inconsistency is a bug and must be resolved by syncing them.

Checkpoints & no-prose rule

• Checkpoints are enforced via DECISIONS.md approvals (- [ ] Approve C*).
• Units with owner=HUMAN block until the corresponding checkbox is ticked.
• Convention: use human-checkpoint as the skill for owner=HUMAN units (keeps semantics explicit; no scripts required).
• Prose writing is only allowed after the required approval (survey default: C2).

Checkpoint approval workflow

DECISIONS.md structure (per checkpoint):

## C2: Structure Approval

**Workspace**: `<current-workspace-name>`
**Artifacts to review**: outline/outline.yml, outline/mapping.tsv, outline/coverage_report.md

- [ ] Approve C2 (outline scope + H2/H3 structure + paper coverage)

Self-check requirement: Each checkpoint block must show the current workspace path to prevent stale approvals.

Approval semantics:

• Unchecked (- [ ]): blocks all downstream units with owner=HUMAN dependency
• Checked (- [x]): unblocks C5 prose writing (for C2) or downstream stages

4) “LLM-first” execution model (recommended)

For semantic units:

• Follow the referenced skill’s Procedure and write the listed outputs directly.
• Only mark DONE when acceptance criteria are satisfied and outputs exist.
• If you use helper scripts to scaffold, treat the outputs as starting points, not final.

For deterministic units (retrieval/dedupe/compile/format checks):

• Use scripts under the skill’s scripts/ folder.

5) Quality Gate Standards (pipeline-auditor)

Deterministic checks (all must pass for PASS status):

Report-class skills contract:

• All report skills (evidence-selfloop, writer-selfloop, argument-selfloop, section-logic-polisher, global-reviewer, pipeline-auditor, artifact-contract-auditor, latex-compile-qa) must write output regardless of PASS/FAIL.
• Self-loop reports are the gate interface (the agent should treat them as “fix plan + unblock signal”):
  • evidence-selfloop → output/EVIDENCE_SELFLOOP_TODO.md
  • writer-selfloop → output/WRITER_SELFLOOP_TODO.md
  • argument-selfloop → output/ARGUMENT_SELFLOOP_TODO.md (and its intermediate ledgers: output/SECTION_ARGUMENT_SUMMARIES.jsonl, output/ARGUMENT_SKELETON.md)
  • deliverable-selfloop → output/DELIVERABLE_SELFLOOP_TODO.md (for non-survey deliverables: snapshot/tutorial/synthesis/review) In all of them, - Status: PASS is the only unblock signal.
• Standard report structure:

  - Status: PASS | FAIL
  
  ## Summary
  <one-line verdict>
  
  ## Warnings
  <actionable issues with line numbers/examples>
  
  ## Details
  <per-check breakdown>
  

• Rationale: Self-healing loop requires failure information to be persisted (see RC2 in PIPELINE_DIAGNOSIS_AND_IMPROVEMENT.md).

6) JSONL Interface Schema (cross-skill contracts)

Survey pipelines treat outline/outline.yml as the ID source of truth. All C2-C4 JSONL artifacts should use those ids directly so downstream skills do not rely on best-effort joins.

If you have legacy artifacts (mixed field names / @BibKey prefixes), run schema-normalizer (NO PROSE) to normalize in-place and write output/SCHEMA_NORMALIZATION_REPORT.md.

Standardized field names (recommended minimum):

Citation key format:

• In JSONL: "citations": ["smith2023"] (no @ prefix)
• In Markdown: [@smith2023] (with @ prefix)
• In BibTeX: @article{smith2023, ...} (entry key)

Required vs optional fields per artifact type (survey pipeline):

• Briefs (outline/subsection_briefs.jsonl): sub_id, title, section_id, section_title, rq, thesis, axes, paragraph_plan.
• Chapter briefs (outline/chapter_briefs.jsonl): section_id, section_title, subsections[] (sub_id, title), throughline, lead_paragraph_plan.
• Evidence bindings (outline/evidence_bindings.jsonl): sub_id, title, plus bibkeys/mapped_bibkeys (raw keys), evidence_ids.
• Evidence packs (outline/evidence_drafts.jsonl): sub_id, title (and section_id/section_title recommended); nested blocks should use raw citations.
• Anchor sheet (outline/anchor_sheet.jsonl): sub_id, title (and section_id/section_title recommended); anchors carry raw citations.
• Writer context packs (outline/writer_context_packs.jsonl): sub_id, title, section_id, section_title; allowed_bibkeys_*; trimmed anchors/comparisons/limitations carry raw citations.

7) Minimal authoring checklist

New skill

• Has SKILL.md with name + description.
• Declares clear Inputs / Outputs and Acceptance criteria.
• If scripts exist: they are deterministic and safe; SKILL.md explains when to use them.
• If outputs JSONL: follows standardized field names from section 6.

New pipeline

• pipelines/<name>.pipeline.md has YAML front matter with units_template.
• Every required_skills listed in the pipeline appears in the units template CSV.
• Units template references only existing skill folders.
• All target_artifacts are produced by at least one unit (no orphaned declarations).

8) Cross-tool compatibility (.claude + .codex)

Codex discovers skills under .codex/skills/. For Claude Code, keep .claude/skills/ pointing at the same set (symlink or copy).

Repo helper: python scripts/validate_repo.py checks pipeline↔template↔skill alignment.

9) Offline-first conventions (optional)

When network is unreliable/unavailable, prefer “record now, verify later” and keep the run auditable:

• Citations: citations/verified.jsonl may include verification_status=offline_generated (recorded but not yet verified). Later, rerun citation-verifier online to upgrade to verified.
• Fulltext: default surveys can run with queries.md evidence_mode: abstract. If you need fulltext, put PDFs under papers/pdfs/ and run pdf-text-extractor with --local-pdfs-only.
