Find Literature

Search academic literature for papers relevant to a query. The search will return a ranked list of papers with relevance scores, summaries, and supporting snippets.

This is an advanced search, so the query can be long and complex. You may ask the user questions to clarify the topic and refine the query before running the search.

Choosing find vs interactive

Two entry points are available. Both run the same retrieval pipeline (criteria extraction, candidate retrieval, re-ranking). The significant difference is what happens around that pipeline — and the right choice is mostly driven by what the session as a whole is about, not by the complexity of any single query:

• asta literature interactive — default for literature-focused sessions. Use it when the first interaction in the session is about literature search or exploration, or when the entire session is focused on literature. It runs the full Asta paper-finder agent: better planning for complex or multi-faceted queries (decomposition, iterative search strategies) and a reasoning / results-verification loop that can re-run or refine the search when the initial results don't satisfy the criteria. It also maintains conversation state via a thread_id, so follow-ups can build on prior results: filtering ("now narrow to surveys from 2023+"), aggregating ("group by venue"), following relations ("expand on the third paper's citations"), or iterative refinement.

• asta literature find — one attempt, no agent loop. Use it primarily when literature search is a sub-step inside some other multi-step flow (data analysis, code generation, a broader research workflow, etc.) where the same flow may issue many unrelated searches and the latency of the full agent loop is not worth it for each one. Lower quality, much faster. Don't reach for find just because a single query "looks simple" — if the session is literature-centered, prefer interactive.

Continuing a conversation — recommended pattern (--thread-dir): for any multi-turn search session, pick a directory named .asta/literature/threads/<YYYY-MM-DD>-<slug>/ (date-prefixed slug, matching the convention used by other agents) and pass it on every turn. The CLI auto-resumes the conversation, writes one artifact per turn with a .NNN index suffix, and maintains a DIR/index.json that records turn order, queries, narratives, paper counts, and the thread_id. Use a meaningful -o basename per turn — the CLI inserts the turn index for you.

# Turn 1 — picks a thread dir; CLI creates DIR/index.json and DIR/transformer-survey.001.json
asta literature interactive "transformer architecture survey" \
  --thread-dir .asta/literature/threads/2026-05-04-transformer-architectures \
  -o transformer-survey.json

# Turn 2 — same dir; thread_id auto-resumes from index.json.
# Writes DIR/narrow-2023.002.json and appends a turn entry to DIR/index.json.
asta literature interactive "narrow to 2023+ long-context surveys" \
  --thread-dir .asta/literature/threads/2026-05-04-transformer-architectures \
  -o narrow-2023.json

Start a fresh conversation when the topic shifts substantially: pick a new --thread-dir. Reading the conversation back is straightforward — jq over DIR/index.json for the turn list, then open the per-turn JSON files referenced by turns[].file.

Without --thread-dir, an invocation is a one-shot turn that doesn't continue any prior conversation. Use that for ad-hoc single queries; for any multi-turn session, always pass --thread-dir.

Output deltas vs find: the interactive JSON adds thread_id and narrative (the agent's terminal response text). It does not currently populate citationContexts or publicationDate per paper; for those, use find or the asta papers commands.

Tools Available

Paper Finder

Run in background for comprehensive searches (30-60s):

# Save to a temporary file with explicit -o parameter (required)
Bash(command="asta literature find 'query' -o /tmp/literature-search-result.json --timeout 300", run_in_background=true)

After the search completes, move the file to .asta/documents/literature/find/ and index it:

# Create directory if it doesn't exist
mkdir -p .asta/documents/literature/find

# Move the result file to the documents directory
mv /tmp/literature-search-result.json .asta/documents/literature/find/

# Index the file using asta-documents
Bash(command="asta documents add file://.asta/documents/literature/find/literature-search-result.json --name='Literature Search: <query>' --summary='Search results for: <query>'")

Browse results with jq:

jq '[.results | sort_by(-.relevanceScore) | .[0:10][] | {title, year, venue, corpusId, score: .relevanceScore, summary: .relevanceJudgement.relevanceSummary}]' <filename>

Go through all highly relevant papers, extracting relevance criteria, snippets, and citation contexts from each.

Semantic Scholar CLI (fast targeted searches)

JSON Structure

The output is a LiteratureSearchResult with the following structure:

Top level:

• query: string - the search query
• results: array of Paper objects

Each paper in results[]:

• corpusId: int - Semantic Scholar corpus ID
• title: string - paper title
• abstract: string | null - paper abstract
• year: int | null - publication year
• authors: array of {name: string, id: string}
• venue: string | null - publication venue
• url: string | null - Semantic Scholar URL
• citationCount: int | null - number of citations
• relevanceScore: float - 0-1 (higher = more relevant to query)
• relevanceJudgement: object with:
  • relevance: int - overall relevance score
  • relevanceSummary: string - AI explanation of relevance
  • relevanceCriteriaJudgements: array of per-concept judgements with:
    • name: string - concept name
    • relevance: int - relevance for this concept
    • relevantSnippets: array of supporting text excerpts
• snippets: array of text excerpts from paper body (if open access):
  • text: string - excerpt text
  • sectionTitle: string - section name
• citationContexts: array of citation contexts:
  • text: string - how other papers cite this work
  • sourceCorpusId: int - corpus ID of citing paper

Example access patterns:

# Top 10 papers by relevance
jq '[.results | sort_by(-.relevanceScore) | .[0:10][] | {title, year, score: .relevanceScore}]' <filename>

# Papers with relevance summary
jq '.results[] | {title, summary: .relevanceJudgement.relevanceSummary}' <filename>

# Extract snippets from a specific paper
jq '.results[] | select(.corpusId == 123456) | .snippets[].text' <filename>

Using Results

After a search completes, results can be used by the Literature Report skill.
