14 tools with schemas present but significant quality gaps. Tool names lack clear action verbs (synapse_remember vs record_fact, synapse_recall vs retrieve_facts). Descriptions are present but generic (avg ~80 chars, below 194-char baseline). Parameters have types and descriptions, but lack constraints (enums, ranges, patterns). No documented output schemas. Error handling and recovery guidance absent. No tool annotations (readOnlyHint, destructiveHint). Composition issues: synapse_remember + synapse_invalidate + synapse_recall form a memory subsystem but lack clear chaining guidance. Wiki tools (write_page, fetch_url, ingest_raw) lack output documentation and error recovery paths.

• Rename synapse_* tools to action-verb form: record_temporal_fact, retrieve_temporal_facts, get_entity_timeline, analyze_causal_relationships, retract_fact. Improves LLM intent inference.
• Document output schemas for all 14 tools. Example for synapse_remember: {success: boolean, fact_id: string, valid_from: ISO8601, valid_to: ISO8601|null}. Required for tool chaining.
• Add enum constraints to free-form parameters: wiki_cluster_pages.algorithm ∈ [louvain, kmeans, spectral]; wiki_lint.check_types already has enum, apply pattern to all similar params.
• Add min/max bounds to numeric parameters: limit ∈ [1, 100], depth ∈ [1, 5], window_days ∈ [1, 365], top_k ∈ [1, 50]. Prevents absurd LLM inputs.
• Add error recovery guidance to descriptions. E.g., synapse_recall: 'If no results, try: (1) broaden query, (2) adjust valid_at timestamp, (3) call query_knowledge for entity discovery.' Guides agent self-correction.
