Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00056 | $0.00716 |
| Opus 5 | $0.00028 | $0.00358 |
| Sonnet 5 | $0.00011 | $0.00143 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade A, and why
literature 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Literature: Source Material Capture
Overview
Launches the literature-capturer agent to capture an external source as a literature note. The agent fetches the source, extracts core ideas in persona voice, finds vault connections and counterpoints, verifies claims, and writes to 2-literature/.
When to Use
/literature <URL>: fetch and capture a web source/literature <paper title or citation>: search for and capture an academic source/literature: no argument; asks the user what to capture- When
/deepenflags uncaptured sources worth preserving
Process
Step 0: Parameter Resolution
No argument (/literature):
Use AskUserQuestion:
What source would you like to capture?
- A URL: I'll fetch and extract core ideas
- A paper title or citation: I'll search for it first
Argument provided: Proceed immediately.
Step 1: Launch Agent
Launch the literature-capturer agent with:
- source: The URL, title, or citation provided by the user
- vault_path:
{{VAULT}}/
The agent definition is at ${CLAUDE_PLUGIN_ROOT}/agents/literature-capturer.md (resolve to a literal path before dispatch — see agents-shared/vault-io.md → Placeholders).
Step 2: Handle Backlink Offers
The agent may identify existing vault notes that reference the source without wiki-links. Present these to the user and execute approved edits.
Step 2.5: Replay Post-Write Hooks
The literature-capturer is a subagent. The literature note it wrote to 2-literature/ bypassed PostToolUse, so backlinks and edge inference didn't run. Replay on the returned path:
printf '%s\n' "$LITERATURE_NOTE_PATH" \
| node "${CLAUDE_PLUGIN_ROOT}/scripts/sweep-hook-replay.mjs" --stdin
Where $LITERATURE_NOTE_PATH is constructed from the agent's response (e.g. {{VAULT}}/2-literature/<filename>, where <filename> is the kebab-case filename literature-capturer returned). The backlink edits from Step 2 happen via main-thread Edit and trigger PostToolUse normally: no replay needed for those. See skills-shared/hook-replay.md for the full pattern.
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.

literature is a skill published in the GitHub repository robinslange/learning-loop (11 stars, last pushed 12d ago), licensed Apache-2.0. It adds 56 tokens to every session and 716 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.
