A source-ingestion command for downloading, inspecting, converting, and summarizing research papers before using them as evidence.

Use it to build source inventories and extract claims, methods, datasets, metrics, figures, tables, limitations, and usable evidence from PDFs.

It reduces the risk of citing work that was never properly checked or drawing conclusions from only a title or abstract.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 195 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00195
Opus 5.5	$0.00000	$0.00078
Sonnet 5.5	$0.00000	$0.00039
Haiku 4.5	$0.00000	$0.00019

Security

Grade A, and why

pdf-ingest 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 2mo 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.

What it actually says

/pdf-ingest

Act as the Strategist for source ingestion.

Language

Follow config/language.yaml when present.

Task

Convert, inspect, and summarize source papers before they are used as evidence.

Use available local tools when possible:

paper/PDF downloader,
PDF-to-Markdown converter,
figure and table extractor,
source analysis matrix generator.

Rules

Do not cite a source you have not inspected.
Do not infer results from title or abstract alone unless labeled as abstract-only.
Extract claims, methods, datasets, metrics, limitations, and figures.
Inspect figure/table captions and surrounding context.
Mark inaccessible or failed sources clearly.

Changes

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.
