Citation Chaining

Expand paper coverage by tracing citation networks in both directions.

Operations

• Backward chaining: ss_references — what does this paper cite?
• Forward chaining: ss_citations — what cites this paper?

Available SOPs

• paper-overview (import) — quick scan of discovered papers
• paper-search (import) — AI summary of promising papers
• paper-research (import) — deep reading of key papers
• saturation-detection (subagent) — determine when to stop

Execution Guidance

• Start from seed/key papers
• Alternate forward and backward passes
• After each pass: filter by relevance, add to reading queue
• Use saturation-detection to stop when new papers aren't adding information
• Track the chain: paper A → cites B → cites C (provenance)
• Deduplicate across passes — same paper may appear in multiple chains

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
knowledge-acquisition-paper-overview	Abstract-level paper scanning for broad coverage. Import of literature-engine/literature-overview skill. Abstract-level only — no methodology conclusions from abstracts.
knowledge-acquisition-paper-research	Full-depth paper reading with raw text extraction. Import of literature-engine/literature-research skill. Must read fullText (true) — equations, hyperparameters, specific claims extracted.
knowledge-acquisition-paper-search	AI-summarized paper reading for intermediate depth. Import of literature-engine/literature-search skill. Must call get_paper_content for every analyzed paper.
knowledge-acquisition-saturation-detection	Determine when additional searching yields diminishing returns. Analyzes the latest expansion batch against existing corpus to judge continue/near-saturation/saturated. Used by snowball and systematic-survey.
