Inspect Candle Analogue

inspect_candle_analogue
Read-onlyIdempotent

Open one neighbour from the reported rankingMethod as an episode: query OHLC, twin OHLC, rebased forward, distance, display similarity, dated permalinks. Not a directional call.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fNoForward horizon in bars. Only the chart presets 5, 10, 30, and 50 are supported
qNoCandles in the matched pattern. Only the chart presets 3, 5, 8, and 12 are supported
rankNo1-based rank in the selected retrieval method's neighbour list (1 = closest).
limitNoClosest analogues to list (1-20). Bands and direction always use the chart's 20 neighbours
symbolNoSupported chart symbol: BTCUSDT, ETHUSDT, or SOLUSDTBTCUSDT
anchorTsNoOptional historical replay anchor in Unix milliseconds. Omit for the latest chart candle
intervalNoSupported chart timeframe: 5m, 15m, 1h, 4h, or 1d5m
token_idNoOptional token. No token or payment is needed during the free access experiment.
chart_tokenNoOptional account key; all tools work anonymously during the free access experiment.
analogueAnchorTsNoTwin episode to open, Unix ms. If omitted, use rank.
includeAnalogueCandlesNoInclude OHLC arrays for every analogue and its continuation. False keeps the response agent-sized

      Previous value: -"Optional Chart access token (64-hex, same as X-Aipp-Chart / the token on /profile). After the daily free MCP quota, paid tools require the Chart $29/mo Stripe subscription.

TDQS

A3.5/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the non-directional scope caveat and a list of returned fields, but says nothing about auth (left to the schema's free-access notes) or any limits.

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

Conciseness4/5

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

Two compact sentences, front-loaded with the action and followed by the field inventory and a scope disclaimer. Dense but every clause carries information; not padded.

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?

For an 11-parameter tool with no output schema, the description usefully enumerates return contents (OHLC pairs, rebased forward, distance, similarity, permalinks), which is exactly the gap an output schema would fill. It stops short of explaining parameter interplay, but the schema covers that.

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 description coverage is 100%, so every parameter is already documented (rank vs analogueAnchorTs selection, enum presets, includeAnalogueCandles response sizing). The description adds no parameter-level meaning, which is the correct baseline when the schema does the work.

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+resource: opens/inspects a single neighbour analogue ('episode') from the reported ranking and enumerates what it surfaces (query OHLC, twin OHLC, rebased forward, distance, similarity, permalinks). 'Not a directional call' distinguishes it from decision/verdict siblings, though the phrase 'as an episode' is jargon-heavy.

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?

Usage is only implied: 'from the reported rankingMethod' signals it is a follow-up to a retrieval/ranking tool, and 'not a directional call' is a when-not hint. No sibling is named as an alternative and no explicit precondition is given, so the agent must infer the ordering.

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