Wiki Ingest PDF

Add one or more PDFs as first-class wiki sources: folder layout, extraction, structured analysis, index update, and ingest in one repeatable pipeline.

Required sub-skills (read before starting):

• geronimo-skills:pdf-parse — extraction tool selection and xberg invocation
• geronimo-skills:research-paper — structured analysis pipeline and anti-slop
• geronimo-skills:kb-conventions — frontmatter schema, annotation markers, layout
• llm-wiki:bootstrap — orient to the target wiki before touching files
• llm-wiki:content — create and update wiki pages with correct frontmatter

Step 0 — Orient to the wiki

Run llm-wiki:bootstrap for the target wiki. Identify:

• Wiki root path (from wiki_config)
• The sources/ section slug and its index.md path
• Existing source slugs (avoid collisions)

Step 1 — Derive slug and paths

From the PDF filename, derive a lowercase-hyphenated slug. Convention: <author>-<short-topic> or <author>-<year>-<short-topic>.

PDF:  Psychisme_modele_constructible_cardon.pdf
Slug: cardon-psychisme

Paths:

<wiki_root>/sources/<slug>/
  original.pdf          ← PDF moved/copied here
  extracted/
    content.md          ← xberg output
  analysis/
    <slug>.md           ← structured analysis
    README.md           ← analysis index
  source.md             ← wiki page (paper.json schema)

Step 2 — Create folder layout and move PDF

mkdir -p <wiki_root>/sources/<slug>/extracted
mkdir -p <wiki_root>/sources/<slug>/analysis
mv <inbox_path> <wiki_root>/sources/<slug>/original.pdf

If the PDF is already in the right place, skip the move.

Step 3 — Create stub source.md

Use the paper type schema from geronimo-skills:kb-conventions. Fill title, tags, read_when from the filename and any known context. Set status: draft, confidence: 0.0, leave tldr and claims empty.

Step 4 — Extract PDF

Follow geronimo-skills:pdf-parse to select the right tool.

xberg (machine-readable PDFs):

# Detect
pdfinfo original.pdf   # check Characters: > 0

# Extract — xberg writes WARN lines to stdout; redirect and strip
xberg extract original.pdf --content-format markdown --page-markers true \
  > /tmp/<slug>_raw.md
grep -vE "^WARN" /tmp/<slug>_raw.md > extracted/content.md

# Verify
wc -w -l extracted/content.md   # sanity: > 500 words for a real doc

marker-pdf (scanned/image PDFs):

uvx marker-pdf marker_single original.pdf --output_dir extracted/

Step 5 — Produce structured analysis

Follow geronimo-skills:research-paper §Step 4. Output: analysis/<slug>.md.

Required sections:

1. Publication details
2. Core thesis ([DIRECT])
3. Key contributions (annotated)
4. Mathematical foundations (or ∅ NOT FOUND IN SOURCES)
5. Algorithms / pseudocode (or ∅)
6. Architecture / system design
7. Experimental results (or ∅)
8. Limitations and open problems
9. Relation to existing KB (use > ✦ NEW:, > ⚠ DIVERGES FROM KB:, > ∅ NOT FOUND IN SOURCES:)
10. Glossary

Apply geronimo-skills:anti-slop before saving.

Create analysis/README.md — one-line entry per analysis file (no frontmatter needed; indexer skips it by design).

Step 5b — Verify analysis frontmatter

Every file in analysis/ that should be indexed must have valid frontmatter. Use llm-wiki:content to verify and fix if needed.

Required fields per geronimo-skills:kb-conventions:

---
title: "Analysis: <Document Title>"
type: note
summary: "<one-line summary>"
read_when:
  - <retrieval condition>
status: active
last_updated: "<YYYY-MM-DD>"
source: "sources/<slug>/original.pdf"
---

Checklist before proceeding:

• type: field present (most common omission — indexer silently skips pages without it)
• status: active
• summary is one line, not a paragraph
• source points to sources/<slug>/original.pdf

extracted/content.md and analysis/README.md intentionally have no frontmatter — leave them as-is.

Step 6 — Update source.md

After analysis, fill in:

• tldr: one-sentence key takeaway
• status: active
• concepts: slugs of wiki concept pages this source informs
• confidence: 0.8–1.0 for [DIRECT]; 0.5–0.7 for [INFERRED]; 0.1–0.4 for [SPECULATIVE]
• claims: 3–7 key claims using the claim schema in kb-conventions

Step 7 — Update sources/index.md

Add a row to the sources table:

| [<slug>](sources/<slug>/source.md) | <Title> | paper | <tags> | active |

Step 8 — Ingest

Use llm-wiki:content to review the final page set, then commit and index with wiki_ingest:

wiki_ingest(wiki: "<wiki-name>", path: "sources/<slug>")

Check the response:

• pages_validated should cover source.md + all analysis/*.md files with frontmatter
• Warnings about no frontmatter on extracted/content.md and analysis/README.md are expected — ignore
• informs edge warnings (target has type 'note', expected concept) mean a slug in concepts: points to a non-concept page — fix the target type or remove the slug and add a [[wikilink]] in the body instead
• All other warnings need investigation before proceeding

After ingest, run wiki_lint and check for orphan warnings:

• An orphan warning on analysis/<slug>.md means source.md has no link to the analysis file — add a [[sources/<slug>/analysis/<slug>]] wikilink in the source.md body and re-run ingest
• 0 errors and 0 warnings (excluding expected no-frontmatter) is the acceptance bar

Multiple PDFs

Run Steps 1–8 for each PDF independently. Do not batch-create slugs or merge analyses. Each PDF gets its own folder and analysis.
