etablissement_by_siret

Read-onlyIdempotent

Retrieve precise establishment details by SIRET number, including legal name, trade name, NAF code, activity status, address, and workforce range from the official INSEE SIRENE API.

Instructions

Récupère le détail d'un établissement par son SIRET (14 chiffres) via l'API SIRENE INSEE V3.11 : raison sociale de l'unité légale, enseigne commerciale, NAF de l'établissement, dates de création/fermeture, statut administratif actif/fermé, adresse complète, tranche d'effectif. Source : SIRENE INSEE V3.11 (api.insee.fr).

Format de retour : objet LookupResult discriminé par found.

  • found: true → établissement à plat (siret, siren, actif, dateFermeture, enseigne, adresse, …)

  • found: false → { found: false, key, lookupStatus: 'not_found', message }. Cas typiques : clé INSEE_SIRENE_API_KEY non configurée côté serveur (message explicite), SIRET inexistant SIRENE, diffusion partielle INSEE.

⚠️ Différence avec entreprise_by_siren : ce tool renvoie UN établissement précis (un site), alors que entreprise_by_siren renvoie l'unité légale + sa liste d'établissements. Pour détecter un SIRET fermé encore listé actif côté FINESS, lire actif: false + dateFermeture.

Pas de coords : l'endpoint INSEE /siret/<siret> ne renvoie pas les coordonnées GPS. Pour géolocaliser, croiser avec geocode_adresse côté caller ou utiliser entreprises_in_radius.

Rate limit INSEE : 30 req/min (retry-after géré côté serveur).

Tool Definition Quality

A4.6/5.0
Behavior5/5

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

Despite comprehensive annotations (readOnlyHint, idempotentHint, etc.), the description adds significant behavioral context: source API, return format (LookupResult with found/not_found cases), error messages for missing key or SIRET, and the fact that GPS coordinates are not returned. No contradictions with annotations.

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?

Well-structured with clear sections (function, return format, sibling differentiation, rate limit). Front-loaded with essential details. Slightly verbose but justified by the depth of 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?

Given the simple input (1 param) and presence of output schema, the description covers all necessary aspects: purpose, behavior, return values, error cases, rate limits, and alternatives. No gaps identified.

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 a single parameter 'siret' described as 'SIRET exact, 14 chiffres.' The description merely reiterates this format, adding minimal additional semantic value beyond the schema definition.

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 clearly states the tool retrieves establishment details by SIRET, listing specific fields (raison sociale, enseigne, NAF, dates, status, adresse, effectif). It also distinguishes from sibling 'entreprise_by_siren', making the purpose unambiguous.

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?

Explicitly explains when to use this tool versus 'entreprise_by_siren' (specific establishment vs legal unit). Provides guidance on detecting closed SIRETs still active in FINESS. Mentions rate limit (30 req/min) and alternatives for geolocation ('geocode_adresse', 'entreprises_in_radius').

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