get_market_themes

Get narrative themes dominating the crypto podcast space on a given date. Each theme includes title, summary, podcast coverage count, fragility score, novelty score and counterfactual narrative.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateNoDate in YYYY-MM-DD format. Omit for latest.
version_infoNoWhen true, include version metadata in the response: both version_num (the revision number) and version_label (a human-readable label like "eod_utc" for the initial end-of-day build, or "revised" when a later-indexed podcast triggered a regeneration). When false (the default), neither field is included. Note: the snapshot generation "status" field is ALWAYS returned regardless of this flag.
snapshot_typeNoAsset universe to draw the snapshot from. Currently only "crypto" is available; "tradfi" is reserved for a future release. Defaults to "crypto".crypto
version_numberNoWhich revision of the snapshot to return. Each snapshot date can be re-generated multiple times (version 1, 2, 3, …). Use -1 (the default) to always get the latest authoritative version (is_latest = true). If you request a specific version that does not exist for the given date + snapshot_type, the latest version is returned instead.

A3.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It does not state whether the operation is read-only, idempotent, or mention any side effects, permissions, or rate limits. The listed output fields offer some insight into the return structure but not into the underlying behavior, which is a significant gap for a tool with no annotation support.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences: the first states the primary purpose, and the second lists the theme attributes. It is front-loaded, contains no unnecessary words, and every sentence earns its place by clarifying what the tool returns.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description compensates by listing the theme fields, offering a clear picture of the response. However, it omits any mention of the versioning behavior or snapshot_type parameter, but those are fully covered in the schema. Given the tool's moderate complexity, the description is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides 100% coverage of all four parameters with clear descriptions, so the parameter semantics are already well-documented. The description adds no additional parameter context beyond the schema, but the high schema coverage makes this a baseline score of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'Get' and resource 'narrative themes dominating the crypto podcast space' with a temporal scope 'on a given date'. It also lists the output fields (title, summary, podcast coverage count, fragility score, novelty score, counterfactual narrative), which clearly distinguishes it from sibling tools like get_market_snapshot and get_market_episodes that do not mention themes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by stating the purpose, but it does not explicitly mention when to use this tool versus alternatives like get_market_snapshot. There are no exclusions or alternative tool references, leaving the agent to infer from the name and description alone. The context is clear but the guidance is minimal.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
