JIT Enablement Engine has 5 well-defined tools with complete input schemas and descriptions. All tools follow verb_noun naming convention (add_, set_, generate_) and have clear, contextual descriptions (100-200 chars). However, there are several medium-severity gaps: (1) Output schemas are not documented, tools return generic text responses without specifying structure for downstream composition. (2) No error handling guidance, failures offer no recovery path or classification. (3) Resource parameter structures differ between tools (add_case_study uses nested label/url objects; add_competitor uses the same; but this inconsistency could confuse agents). (4) No parameter enums where they should exist (e.g., segment, category, relevant_stages could be constrained). (5) The generate_enablement tool's deal_stage and industry parameters accept free-form strings instead of predefined values from the knowledge base. These are reasonable tools for a domain-specific sales enablement engine, but lack the guardrails and composition clarity expected of production-grade agent tools.

• Document the output structure for each tool. Instead of returning generic text, define a typed response: { success: bool, id?: string, entry_count?: number, details?: object }. This enables agents to extract and chain results.
• Add error handling guidance to tool descriptions. E.g., 'Fails if company name is empty (user-fixable) or if disk is full (retryable). Returns error message stating which.' Include recovery hints like 'If conflict, try update_case_study instead.'
• Convert free-form 'segment' parameter to enum constraint: z.enum(['Enterprise', 'Mid-market', 'SMB']). Apply same pattern to 'category' in add_competitor and add_objection.
• Add deal_stage enumeration to generate_enablement. Load valid stages from KB.methodology.stage_guidance.keys() and constrain input to known stages. Document: 'Must match a stage in your methodology.'
• Document constraints on relevant_stages values. Add to description: 'Each stage must match a stage in your sales methodology. Current valid stages: [Proposal Sent, Negotiation, ...]'
• Implement idempotency guarantees. If add_case_study is called twice with identical company/industry/challenge, the second call should return the existing entry's ID without duplicating. Add documentation: 'Idempotent, calling twice with same input returns same ID.'
• Add permission declarations to tool descriptions. E.g., 'Requires: knowledge-base:write'. This clarifies scope for least-privilege agent configuration.
• Expand generate_enablement response to return structured data: { deal_name, relevant_case_studies: [{id, company, metric}], competitor_positioning: [...], objections: [...], methodology_name, ... }. This enables agents to act on structured results.
