This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"description": "Identifies an integer sequence from terms (a JSON array or pasted text), an OEIS A-number, a safe-parsed formula or recurrence, or a description, and leads with a verdict, confidence, A-number, formula, next terms and a next step. Searches the OEIS directly, then superseeker-style (differences, partial sums, gcd, ratios, binomial, Euler, leading terms, plus a search without the last two terms to flag disagreeing terms) under an 8-search budget, aligns offsets, and marks which terms agree or disagree. Fits linear recurrences and polynomials exactly over the rationals and reports one only when it predicts held-out terms. Candidates are ranked in code; a model is used only for a description input (one fast call, OEIS confirms what it proposes) and for the optional explain sentence (one more call, quote verified against OEIS text). Output carries the CC BY-SA 4.0 OEIS attribution. Price: 0.10 USDC. Endpoint: POST https://agents.writerslogic.com/api/v1/identify-sequence",

"description": "Leads with a verdict (OPEN_GAPS_FOUND, NO_CLEAR_OPEN_GAPS or NO_GAPS_EXTRACTED), a confidence, a headline naming the top gap with its quoted evidence, and the next step. Collects papers for a topic or seed list (arXiv ids or URLs, DOIs, PMIDs; arXiv and OpenAlex search), reads full text from ar5iv or Europe PMC, and extracts future-work, limitation and open-question sentences in code with exact section spans. Near-duplicates are clustered across papers, then each cluster is checked against later citing works (OpenAlex cites, Semantic Scholar citation contexts) and marked OPEN, POSSIBLY_ADDRESSED or ADDRESSED. Scores combine recurrence across independent author groups, recency, citation momentum and openness with documented formulas. mode \"fast\" makes zero model calls; the default makes two (cluster wording, addressed judgment) and lets them move a status at most one level. OPEN means no scanned citing paper covered the theme, not that nobody has: the check reads titles, abstracts and citation contexts of up to a few hundred citing works, not their full text. Papers without open full text contribute only abstracts. Price: 1.50 USDC. Endpoint: POST https://agents.writerslogic.com/api/v1/mine-future-work",

"description": "Checks every reference in a bibliography against Crossref, OpenAlex, arXiv and Europe PMC and leads with a verdict (FIX_REQUIRED, REVIEW_RECOMMENDED, INCOMPLETE or ALL_VERIFIED), a confidence, a one-line headline, the next step and a prioritized fix list. Input: BibTeX, LaTeX \\bibitem, a plain-text list (APA, IEEE, Vancouver), an arXiv id (read via ar5iv), a PDF URL, or just a list of DOIs, arXiv ids and PMIDs. Each reference is VERIFIED, METADATA_MISMATCH (field-level year, author, title, venue and DOI diffs), DOI_RESOLVES_TO_DIFFERENT_WORK, NOT_FOUND (likely fabricated or mistyped), RETRACTED or HAS_CORRECTION (Crossref updated-by, OpenAlex is_retracted, Europe PMC notices), PREPRINT_NOW_PUBLISHED (with the version of record), DUPLICATE_ENTRY or UNRESOLVABLE (an index was down; reported as a partial result, never as NOT_FOUND). With manuscript text, unresolved \\cite keys and uncited entries are reported. All verdicts are computed in code with zero model calls; checkSupport adds one fast-tier call judging whether each cited abstract supports its citing sentence, both quotes verified. Limited to indexed works: books, theses, standards and web pages are often NOT_FOUND or UNRESOLVABLE, and a clean result is not an endorsement of the cited claim. Price: 1.50 USDC.

"description": "Audits the dependencies of a public GitHub repo, commit or pull request (or uploaded manifests and sources) and returns a pass/warn/fail verdict, a 0-100 risk score, the top findings with manifest file:line and the fix, and a SARIF 2.1.0 log for GitHub code scanning. Parses JS/TS, Python and Rust imports with a tokenizer-level scanner and maps them to declared npm, PyPI and crates.io dependencies. Flags unused, dev-only, undeclared and trivially used packages; checks deps.dev, the npm registry and OSV for deprecation, advisories, staleness and OpenSSF Scorecard; matches a cited table of platform replacements (fetch, crypto.randomUUID, optional chaining) and ranks alternatives in code by Scorecard, recency, dependents, size and license compatibility. Reads repos through GitHub's API and falls back to the source archive when the API is rate limited; when some lookups still fail, it returns a signed partial result that lists what is missing. At most one optional model call maps used symbols to a replacement; deterministic mode makes none. Advisory data comes from OSV and deps.dev and can lag; findings are leads to verify, not a certification. Price: 1.00 USDC. Endpoint: POST https://agents.writerslogic.com/api/v1/audit-dependencies",
