capture

capture is a skill for Claude Code from ignromanov/llm-obsidian-wiki. It costs 69 tokens per session (933 once invoked), scanned A, original, MIT.

A source-ingestion tool that stores an original source and creates a structured summary in a wiki vault.

In plain words
What is it for?
Use it to capture web pages, videos, GitHub issues or pull requests, PDFs, copied text, and session logs into raw files and source-summary pages.
Why use it?
It gives research material a consistent location, integrity check, and set of claims that other wiki pages can reference.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

capture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Capture — Universal Source Intake

Purpose

Ingest one source into raw/<type>/<slug>.<ext> (immutable, SHA-256 hashed) and create wiki/sources/<slug>.md (source-summary with key_claims[]).

Used by wiki-scribe (primary, passive intake) and wiki-researcher (via research workflow).

Trigger phrases (agent perspective)

  • "capture this URL"
  • "save this PDF"
  • "intake source"
  • "file clipboard"
  • "hash and store this"
  • "wiki-scribe should ingest X"

Inputs

One of:

  • URL (any https://)
  • YouTube link
  • GitHub link (issue / PR / repo)
  • PDF (path or URL)
  • Raw text (clipboard, session log, transcript)

Outputs

Two files per capture:

  1. raw/<type>/<slug>.<ext> — immutable, SHA-256 in frontmatter, full content
  2. wiki/sources/<slug>.md — source-summary with key_claims: [{quote, anchor, confidence}], quality, captured_by

Workflow

  1. Detect source type from URL or path:

    • *.pdf → capture-pdf.sh
    • youtube.com/* or youtu.be/* → capture-youtube.sh
    • github.com/*/issues/* or */pull/* → capture-github.sh
    • github.com/*/pulls → capture-prs.sh
    • text without URL → capture-text.sh
    • other URL → capture-url.sh

  2. Invoke the appropriate script with --vault $VAULT_PATH and --source $INPUT. Scripts handle SHA-256 and frontmatter.

  3. Extract key_claims for source-summary:

    • If source <500 words: preserve full content as single claim
    • If 500–5000 words: top-5 verbatim quotes with anchors (paragraph index)
    • If >5000 words: top-10 quotes with anchors

  4. Set quality field in source-summary:

    • high if extraction succeeded with >500 chars
    • medium if 200-500 chars (paywall preview, partial)
    • low if <200 chars or extraction errors

  5. Set captured_by to invoking agent name (wiki-scribe or wiki-researcher).

Web→MD stack (for capture-url.sh)

The script tries three extractors in order:

  1. defuddle (Node CLI, MIT, local) — primary
  2. trafilatura (Python CLI, Apache-2.0, local) — fallback if defuddle fails OR content <500 chars
  3. r.jina.ai (cloud) — opt-in via env WIKI_ALLOW_CLOUD=1

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

capture is a skill published in the GitHub repository ignromanov/llm-obsidian-wiki (19 stars, last pushed 3mo ago), licensed MIT. It adds 69 tokens to every session and 933 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
