Valuein — SEC EDGAR Fundamentals & Smart-Money Data

List Signals

list_signals

Read-onlyIdempotent

Paginated newest-first listing of the caller's signals (id, condition, channel, status, trigger_count, evaluator health). Filter by status (active/paused/deleted/all). Use the returned signal id with delete_signal or test_signal. Tier: sp500+ (sample rejected).

Input Schema

Name	Required	Description	Default
`limit`	No	Maximum number of signals to return (1–100). Defaults to 20.
`cursor`	No	Opaque pagination cursor from a previous response; omit for the first page.
`status`	No	Filter by lifecycle state; defaults to `active`. Use `all` to include paused and soft-deleted signals.	active

Output Schema

Name	Required	Description
`_meta`	Yes	Provenance envelope — data lineage for every MCP response
`signals`	Yes
`next_cursor`	Yes
`total_count`	Yes

It is a floor for a single filer, not a ceiling: a filer with a live partition receives its filing, facts and ratios intraday (minutes after EDGAR dissemination), so an entity-scoped read may carry a filing newer than this; cross-sectional ranks (factor scores, earnings signals) refresh with the weekly bulk export."

TDQS

A4.3/5.0

Behavior5/5

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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, and the description still adds substantive context beyond them: newest-first ordering, pagination via cursor, the concrete returned fields including evaluator health, and a tier gate (sp500+, sample rejected) that determines whether the call will succeed at all.

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?

Three dense sentences, front-loaded with the resource and ordering, then filtering, then chaining and the tier constraint. No filler; the parenthetical field list is compact and useful.

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

Completeness5/5

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

For a paginated read-only list with an output schema, the description covers ordering, pagination, filtering, downstream chaining, and access tier. Nothing an agent needs to invoke it correctly is missing, and it does not waste space re-explaining return shapes.

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?

Schema coverage is 100%, so all three parameters are already documented, and the description mostly restates the `status` enum values and default. It adds no syntax or semantics for `limit` or `cursor` beyond what the schema says, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb and resource ('Paginated newest-first listing of the caller's signals') plus the fields returned and the ordering, so the agent knows exactly what it gets. It does not explicitly differentiate from the nearby sibling list_signal_inbox, which is the one ambiguity left.

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

Usage Guidelines4/5

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

Gives clear context: filter by `status`, and the returned id feeds delete_signal or test_signal, which tells the agent where this tool sits in a workflow. There are no explicit exclusions or 'use X instead' statements, so it stops short of a 5.

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