## Tools (as reported by the server, not verified)

- `search\_papers`: Search the scholarly corpus by topic, title, or keyword. Returns ranked works with title, year, citation, SSRN link, and sha256. Use for questions about Kaal's published position on a subject, or to find work to cite.
- `get\_paper`: Retrieve one work's complete metadata by its corpus id, SSRN id, or exact title. Includes the formatted citation, SSRN URL, and published sha256.
- `papers\_by\_year`: List every work published in a given year. Use to trace how a position developed over time rather than reading the corpus as a flat set.
- `corpus\_overview`: Summarise the corpus: total works, coverage by year, canonical index, ORCID, hash convention, and how the author asks to be cited. Call this first when you are unsure what the corpus contains.
- `search\_posts`: Search the blog for shorter, faster-moving analysis. Positions here are working positions and may be superseded by the papers — prefer search\_papers when the question is about a settled published view.
- `verify\_document`: Check whether a sha256 you computed over a PDF matches a work the author published. Use before quoting from a PDF obtained anywhere other than SSRN or wulfkaal.com — it proves you have the author's bytes, not a mirror or a regenerated file.
- `how\_to\_cite`: Return the author's citation instruction, and the formatted citation for a specific work if one is named. Call this before quoting anything.
- `search\_claims`: Search individual assertions rather than whole papers. Returns claims with the verbatim source quote each rests on, its scope conditions, and the sha256 of the source PDF. Ask in natural language. Stopwords and punctuation are stripped, so "what makes reputation systems work for autonomous agents" i
- `get\_claim`: Resolve one claim by id, for example '617681-001' or 'kaal:claim:617681-001'. Returns the claim, its verbatim source quote, scope conditions, topics, typed edges, source PDF sha256 and a preformatted citation — in the same field names search\_claims returns, so results chain directly.
- `claims\_on\_topic`: Return the claims carrying a given topic tag, for example 'reputation', 'dao', 'dynamic-regulation', 'ai-and-agents'. Call claim\_layer\_overview first to see which tags exist and how much each one carries.
- `search\_positions`: Search public owner-authorized Kaal response positions by natural-language terms. Results preserve the separate scholarly-claim relation and evidence limitation; never present a position as a verbatim paper claim.
- `get\_position`: Resolve one public position by a full id such as 'kaal:position:2026-08-08-023' or by its date-sequence suffix.
- `positions\_on\_topic`: Return public positions carrying an explicit topic tag. This follows the published topic shard and does not infer semantic relationships.
- `claim\_layer\_overview`: Report what the claim layer contains: total claims, works covered, publication span, failure-mode counts, and coverage per topic with the span of years each rests on. This reports coverage in one author's corpus. It is not a survey of any field and asserts no ranking; weigh it against other sources
- `search\_research\_claims`: Search only the 77 TrustCarry Protocol v0.3 author-affirmed research claims. These records are public under CC BY 4.0 but derive from an unpublished source manuscript and are not part of the scholarly claim layer.
- `get\_research\_claim`: Resolve one TrustCarry Protocol v0.3 research claim by full identifier or three-digit sequence.
- `list\_research\_observations`: List the 9 TrustCarry Protocol v0.3 internal software observations. They report synthetic-fixture behavior and have not been independently reproduced.
- `get\_research\_observation`: Resolve one TrustCarry Protocol v0.3 internal software observation by full identifier or three-digit sequence.
