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

TableJSON 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

Use THIS — not `last_updated` — when telling a user how current the cross-sectional fundamentals are. The snapshot is republished on every weekday price refresh while the statements are carried forward unchanged, so `last_updated` can be far more recent than the numbers it sits next to. 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

Behavior4/5

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

Annotations already declare read-only, idempotent, and non-destructive. The description adds caller scoping, newest-first ordering, pagination behavior, and the access-tier restriction 'Tier: sp500+ (sample rejected)', which is behavioral beyond structured fields. No contradiction.

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 compact sentences, each earning its place: listing behavior, filter values, downstream usage, tier rule. Front-loaded with core listing semantics before auxiliary notes, with zero waste.

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?

Complete for a read-only list tool with an output schema: specifies pagination mechanism, ordering, default/available filters, caller scope, and downstream consumers. The tier restriction covers access behavior that would not otherwise be inferable.

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% with descriptions for all three params (limit constraints, cursor semantics, status enum). The description repeats the status options but adds no new parameter meaning beyond the schema, and there are no undocumented parameters needing compensation.

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?

States a specific verb ('listing'), resource ('the caller's signals'), and behavioral specifics (paginated, newest-first) with named return fields. This distinguishes it from sibling list tools such as list_signal_inbox (inbox items) and get_earnings_signals (market signals). The scope 'caller's' makes ownership explicit.

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?

Clearly describes the context: paginated listing with status filtering (active/paused/deleted/all) and a default of active. It also chains to sibling tools ('Use the returned signal id with delete_signal or test_signal'), but does not explicitly state when to prefer it over list_signal_inbox or other list tools, nor any exclusions.

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