paper-trail-inject-url is a command for Claude Code from roomi-fields/paper-trail. It costs 41 tokens per session (766 once invoked), scanned A, original, MIT.

A command for manually supplying an open-access URL for a research reference when automatic searching cannot find its PDF. Open access means the paper can be read online without a paywall.

In plain words
What is it for?
Use /paper-trail:inject-url with a reference slug and URL from sources such as an author page, university repository, HAL, or NIME.
Why use it?
It removes the need to edit the reference by hand when you already know where the paper is available, and then retries downloading and checking it.

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

paper-trail-inject-url 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 1mo 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.

/paper-trail:inject-url <slug> <url> — URL OA fournie manuellement

Quand la cascade automatique épuise toutes ses sources mais que vous savez où le PDF est disponible (page d'auteur, dépôt universitaire, HAL, NIME, eScholarship…), cette commande injecte l'URL dans le frontmatter de la ref puis relance la cascade. Aucun bricolage manuel.

Le résolveur landing→PDF du pipeline suit automatiquement la balise <meta name="citation_pdf_url"> (norme Highwire Press), donc une URL de page de dépôt fonctionne — pas besoin du PDF direct.

Usage

/paper-trail:inject-url <slug> <url>

Exemple :

/paper-trail:inject-url murgul_2024_polyrhythm \
    https://publikationen.bibliothek.kit.edu/1000183782

Ce que fait Claude

  1. Vérifie la ref : la ref <slug> doit exister dans le registre et être en état uid_resolved, needs_reacquisition, ou blocked_human:cascade_exhausted_needs_manual. Sinon refuse en expliquant.

  2. Écrit oa_url: dans le frontmatter :

    python3 -c "
    import sys; sys.path.insert(0, 'pipeline')
    from pipeline.registry import load_ref, save_ref
    r = load_ref('<slug>')
    r.frontmatter['oa_url'] = '<url>'
    save_ref(r)
    "
    
  3. Si la ref était bloquée, débloque-la pour que la cascade puisse la reprendre :

    python3 -m pipeline arbitrate <slug> --decision unblock \
        --reason "manual oa_url provided"
    
  4. Relance la cascade ciblée :

    python3 -m pipeline run --ref <slug>
    

    La nouvelle source manual_oa_url est en tête de cascade donc essayée en premier.

  5. Récap : si succès, affiche le chemin PDF + sha256 ; sinon liste ce qui a échoué (HTTP 404, page sans citation_pdf_url, validation page 1 KO, etc.) et propose les pistes du fichier _hints/<slug>.md généré automatiquement.

Quand utiliser

  • Le fichier _hints/<slug>.md a été généré (la cascade a épuisé) ET vous connaissez une URL OA fiable.
  • Plus rapide que de télécharger le PDF à la main puis renseigner pdf_path manuellement.

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.
