Document Grounding

Convert a raw document into a structured grounding note.

This skill is for document grounding, not a narrative recap. It should produce a stable intermediate note that is easy to read and easy for downstream skills to use.

When to Use

Use this skill when:

• the input is a single document file
• the document may be a PDF, DOCX, Markdown, or TXT file
• you need structured document notes before downstream research or summary work
• the document may contain non-textual evidence such as tables, figures, diagrams, formulas, or code blocks

Do not use this skill when:

• the task is to write a polished final report
• the task is to perform external literature search
• the task is to render output into PDF/DOCX
• the input is a meeting transcript and you want meeting-specific grounding

Input

A single document file.

Supported first-stage formats:

• .pdf
• .docx
• .md
• .txt

The document may contain:

• plain text
• section headings
• tables
• figures / diagrams
• formulas
• code blocks
• captions
• layout / reading-order challenges

Output Bundle

For each input document, create one bundle directory:

data/grounded_notes/<type>-<doc_id>_<timestamp>/

where <type> is the file extension (e.g. pdf, docx, md, txt), <doc_id> is the sanitized filename without extension, and <timestamp> is the Beijing-time execution timestamp (format: YYYYMMDDHHMMSS).

For example:

data/grounded_notes/pdf-paper_name_20260410153022/
data/grounded_notes/docx-notes_001_20260410153100/
data/grounded_notes/md-project_readme_20260410153215/

Inside that bundle, the expected outputs are:

<bundle_dir>/
├─ ground_id.txt       # Ground ID for this unit (reused by all downstream stages)
├─ extracted.md
├─ extracted_meta.json
├─ asset_index.json
├─ grounded.md
└─ assets/
   ├─ tables/
   ├─ figures/
   └─ formulas/

The <ground_id> (e.g. pdf-paper_name_20260410153022) is the single stable identifier for the entire pipeline — all downstream directories (lit_inputs, lit_results, report_inputs, review_outputs, reports, final_outputs) reuse this same <ground_id>.

Important separation of responsibilities

• ground_document.py is responsible for building the extraction bundle:
  • extracted.md
  • extracted_meta.json
  • asset_index.json
  • assets/...
• The agent is responsible for reading those outputs and then writing the final:
  • grounded.md

grounded.md must be a real grounding note. It must not remain a placeholder scaffold.

Required Agent Workflow

1. Run the extraction script through the existing run.sh entrypoint.
2. Read:
   • extracted.md
   • extracted_meta.json
   • asset_index.json
3. If extracted.md contains AssetRef blocks, inspect the referenced files in assets/... before writing grounded.md.
4. Write grounded.md as a real structured grounding note.
5. Do not stop after merely confirming that the extraction bundle exists.

AssetRef Rule

extracted.md may contain blocks such as:

[AssetRef]
type: figure
id: figure_001
path: assets/figures/figure_001.png
instruction: Inspect this asset before writing grounded.md if it is relevant to the document's claims, comparisons, or conclusions.
[/AssetRef]

and

[AssetRef]
type: table
id: table_001
path_md: assets/tables/table_001.md
path_csv: assets/tables/table_001.csv
instruction: Inspect this table before writing grounded.md if it contains key evidence, comparisons, or numerical results.
[/AssetRef]

These are not decorative markers. They indicate that important evidence may exist outside the plain extracted text. If an AssetRef appears relevant, the agent must inspect the referenced asset before final grounding.

Output Format

Return markdown with exactly these sections.

# Document Grounding

## 1. Main Topic / Purpose
[2–4 sentence statement of the document’s main topic and purpose.]

## 2. Main Points
- [One bullet per major sub-topic, contribution, or argument]

## 3. Key Findings / Claims
- [Only items explicitly stated or strongly supported by the document]

## 4. Constraints / Risks
- [Only constraints, limitations, caveats, or risks explicitly stated or strongly supported by the document]

## 4a. Important Non-Textual Elements
- [Key tables, figures, diagrams, formulas, or code blocks that materially affect interpretation]
- [Mention how they affect the reading of the document if relevant]

## 5. Unresolved Issues
- [Preserve uncertainty, unanswered questions, incomplete evidence, or limitations that remain open]

## 6. Suggested Next Steps
- [Concrete follow-up directions grounded in the document]
- [Do not invent owners, deadlines, or commitments]

## 7. Search Keywords

### Problem Keywords
- ...

### Method / Solution Keywords
- ...

### Domain / Constraint Keywords
- ...

Instructions

• Do not write a chronological recap of the document.
• Do not invent facts, conclusions, owners, deadlines, or commitments.
• Do not turn suggestions, hypotheses, or future work into established conclusions.
• Do not add external knowledge, acronym expansions, years, benchmark details, or metadata not explicitly stated or strongly evidenced in the document.
• Remove low-signal boilerplate when it does not affect meaning.
• Group related content into high-level sub-topics instead of page-by-page bullets.
• Keep the output concise and structured.
• Treat non-textual evidence as first-class evidence when relevant.

Special Rules

Key Findings / Claims

Only include something here if it is explicitly stated or strongly supported by the document. If it is merely hinted, proposed, or speculative, do not present it as a confirmed finding.

Constraints / Risks

Only include constraints, limitations, or risks that are explicitly stated or strongly evidenced. Do not infer hidden constraints from weak hints.

Important Non-Textual Elements

Only mention tables, figures, formulas, diagrams, or code blocks that materially affect interpretation. Do not list every asset mechanically. If an asset was referenced in extracted.md through an AssetRef block and it appears relevant, inspect it before deciding whether to include it.

Suggested Next Steps

Only include follow-up actions or directions that are explicitly discussed or strongly implied by the document. Do not invent action owners, deadlines, or commitments.

Search Keywords

Use specific noun phrases that are useful for later search. Avoid generic terms such as:

• project
• document
• update
• issue
• optimization
• system

Handling Difficult Cases

• If the document is repetitive, summarize repeated points once.
• If the document is incomplete, paraphrase only when meaning is clear.
• If sections conflict, keep the conflict under unresolved issues.
• If the main topic is genuinely unclear, write: Unclear — multiple loosely related topics appear in the document.
• For long documents, identify major section shifts first, then synthesize.
• If non-textual assets are present but unclear, mention them cautiously rather than over-claiming their meaning.

Execution Rule

The task is not complete if grounded.md is missing, empty, or still contains placeholder scaffold text. The agent must overwrite or newly create grounded.md with a real grounding note based on:

• extracted.md
• extracted_meta.json
• asset_index.json
• any relevant files referenced from assets/...

Example Invocation

/document-grounding

Environment Variables

When running the extraction script, ensure the Docling model path is set:

export DOCLING_ARTIFACTS_PATH="${PROJECT_ROOT}/models/docling"

Supported model path locations (checked in order):

• ${PROJECT_ROOT}/models/docling
• ${PROJECT_ROOT}/models/docling-project/docling-models
• /root/.cache/docling/models
