Market Intelligence

get_market_intel

Read-onlyIdempotent

Use this when the user asks about a data-center market (metro supply, operators, pipeline, pricing): facility count, tracked MW, status mix, top providers, recent facilities or lease pricing. Pass market as a slug (e.g. northern-virginia). Returns stats, by_status, top_providers, recent_facilities, market_pricing (quote its basis). Verdict: use get_market_dcpi_rank. Keyless: a trimmed preview; a free key gets more. Ex: "1 MW colo price in Los Angeles?" Get the market slug from rank_markets or get_market_dcpi_rank; 404 = unrecognised market, use one of those slugs.

Input Schema

Name	Required	Description
`market`	No	Market slug (metro), e.g. northern-virginia, dallas, frankfurt, singapore — valid slugs come from rank_markets / get_market_dcpi_rank
`metric`	No	Optional single metric to focus on, e.g. vacancy, pricing, absorption, pipeline
`period`	No	Optional time window for the metric, e.g. ttm, 12mo, ytd
`mpp_pay`	No	Per-call payment quote (Stripe MPP): true returns a signed payment challenge instead of the free preview; no money moves. Set it only after your human has explicitly approved paying for this call.
`compare_to`	No	Optional second market slug to compare against, e.g. dallas
`mpp_credential`	No	Per-call payment (Stripe MPP): the Shared Payment Token for challenges[0]; pays that challenge for this one call. Send it only with your human's explicit approval of the charge.

Output Schema

Name	Required	Description	Default
`stats`	No
`_gated`	No
`market`	No
`success`	No
`by_status`	No
`related_intel`	No
`top_providers`	No
`recent_facilities`	No

A4.6/5.0

Behavior4/5

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

Annotations already cover readOnly/idempotent/non-destructive/openWorld=false, so the description focuses on behavior they don't convey: keyless calls return a trimmed preview, a free key unlocks more, mpp_pay returns a signed challenge with no money movement, and 404 means unrecognised market. Missing only details like rate limits or preview truncation specifics.

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?

Dense but front-loaded: trigger first, then payload, then verdict/alternative, then auth tier, then slug sourcing. The inline example query and the repeated slug guidance cost a little space but each line carries actionable information.

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 six-param, read-only, output-schema-bearing tool, the description covers trigger, scope, return-shape, alternative routing, auth tier, and error recovery. An agent has everything needed to call it correctly and interpret gaps.

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

Parameters4/5

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

Schema coverage is 100% so baseline is 3, but the description adds real meaning: market must be a slug with concrete examples, market_pricing should have its basis quoted, and the slug-provenance rule ties back to rank_markets. Payment-approval caveats for mpp_pay/mpp_credential are also surfaced in-schema, so the marginal gain is modest.

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+resource (data-center market intel) and enumerates exactly what it covers: facility count, tracked MW, status mix, top providers, recent facilities, lease pricing. It explicitly distinguishes itself from the sibling get_market_dcpi_rank ("Verdict: use get_market_dcpi_rank"), so an agent can route correctly without opening either schema.

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

Usage Guidelines5/5

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

Gives an explicit trigger (user asks about a metro market), names the alternative for rankings (get_market_dcpi_rank), and states where valid slugs come from (rank_markets / get_market_dcpi_rank) plus the 404 recovery path. It also flags the keyless-preview vs free-key tradeoff, which affects tool choice.

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