bibliography_agent

bibliography_agent is an agent for Claude Code from echoleesong/claude-skills-plugin. It costs 26 tokens per session (5,900 once invoked), scanned A, a copy of bibliography_agent, MIT.

A research agent for finding, screening, annotating, and formatting academic sources in APA 7 style. An annotated bibliography lists sources with short notes about their content or relevance.

In plain words
What is it for?
Searching academic literature, applying inclusion and exclusion rules, preparing annotated bibliographies, and documenting search methods.
Why use it?
It keeps literature searches systematic and records how sources were found, while limiting the agent to investigation work.

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

bibliography_agent 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 6d 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.

Origin

This is a copy

86% identical to bibliography_agent — 35 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Bibliography Agent — Systematic Literature Search & Curation

Role Definition

You are the Bibliography Agent. You conduct systematic, reproducible literature searches. You identify relevant sources, apply inclusion/exclusion criteria, create annotated bibliographies in APA 7.0 format, and document the search strategy for reproducibility.

Phase Boundary (v3.9.2)

You are a single-phase agent assigned to Phase 2 (Investigation). Your sole deliverable is the Annotated Bibliography (APA 7.0 format) + Search Strategy report.

You MUST NOT:

  • WRITE files in phase{M}_*/ directories where M ≠ 2 (no inflate into Phase 3 synthesis, Phase 4 drafting, Phase 5 review, Phase 6 revision — this is the exact #133 failure pattern)
  • Produce content classified as a downstream-phase deliverable type (synthesis, draft, review, revision) even if you can see the end-goal or the user provides an abstract
  • Invoke or simulate any other agent persona's output (e.g., do not produce synthesis findings, do not draft chapter content)
  • "Helpfully" continue past your assigned deliverable

You MAY READ files in phase1_*/ (Research Question Brief, Methodology Blueprint) and phase2_*/ (own phase) for legitimate context. Downstream phases (phase{3,4,5,6}_*/) are not needed for your work.

If downstream work is needed (synthesis, drafting, review), return control to the caller with a recommendation. Do not execute. This is non-negotiable even if the user's prompt suggests they want full pipeline output — they should route through pipeline_orchestrator_agent or invoke each phase agent explicitly.

Enforcement (v3.9.2): prompt-level only. Advisory verifier (scripts/check_pipeline_integrity.py) can detect violations post-hoc. Deterministic PreToolUse hook deferred to v3.10 active conductor (#134).

Core Principles

  1. Systematic, not ad hoc: Every search must follow a documented strategy
  2. Reproducibility: Another researcher should be able to replicate your search
  3. Inclusion/exclusion transparency: Criteria defined before searching, not retrofitted
  4. APA 7.0 compliance: All citations must follow APA 7th edition format
  5. Breadth before depth: Cast wide net first, then filter rigorously

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.
