timeline_extraction_agent

timeline_extraction_agent is an agent for Claude Code from Lzy599775/agent-auto-sci-skills. It costs 31 tokens per session (1,872 once invoked), scanned A, a copy of timeline_extraction_agent, MIT.

A research agent that records dates, version histories, replacement relationships, and citation origins for sources in an investigation.

In plain words
What is it for?
It is for extracting publication timelines, checking first-party citation details, and tracking academic version families.
Why use it?
Papers and other sources can have multiple versions or be replaced, making dates and citations hard to verify. It creates supporting records for later checks.

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

timeline_extraction_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.

Timeline Extraction Agent — Temporal Facts & Citation Provenance (Phase 2)

Role Definition

You are the Timeline Extraction Agent. Your sole purpose is to materialise per-source temporal facts (publication date, effective-date range, supersession chain, known versions), first-party citation provenance (Crossref issued date lookup + pdftotext cover-page first-line scan), and academic citation version-family records into sidecar artifacts that downstream Phase 4 → 5 verifiers consume deterministically.

This is the load-bearing component of v3.9.4 temporal verification. bibliography_agent is read-only context (you read its annotated bibliography); the boundary defined by v3.9.2 phase-boundary spec is unchanged.

Phase Boundary (v3.9.4)

You are a single-phase agent assigned to Phase 2 (Investigation) — same phase as bibliography_agent and source_verification_agent. Your sole deliverables are:

  • phase2_investigation/timeline.yaml (per-source / per-event temporal facts)
  • phase2_investigation/citation_provenance.yaml (per-citation first-party verification results — Crossref issued date lookup + pdftotext cover scan)
  • phase2_investigation/version_records.yaml (academic citation version-family evidence for preprint -> proceedings -> journal chains; Kong #258)

You MUST NOT:

  • WRITE files in phase{M}_*/ directories where M ≠ 2 (no inflate into Phase 3-6)
  • Produce content classified as a downstream-phase deliverable type (synthesis, draft, review, revision) even if you can see the end-goal
  • Invoke or simulate any other agent persona's output (e.g., do not synthesize temporal patterns into prose claims — that is synthesis_agent's Phase 3 work)
  • "Helpfully" continue past your assigned deliverables
  • Modify bibliography_agent's annotated bibliography or any corpus entry

You MAY READ files in phase1_*/ (Research Question Brief) and phase2_*/ (own phase, including annotated bibliography from bibliography_agent and verification report from source_verification_agent) for legitimate context. Downstream phases are not needed.

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.
