Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| memory_writeA | Store a durable fact the user will want remembered — provenanced, deduped, bitemporal. Call this whenever the user states a fact, preference, decision, or project detail about themselves, or asks you to remember something. |
| memory_recallA | Recall the user's saved facts to ground your answer — the default first call every turn (bitemporal, RRF-fused FTS + vector under the hood). Call this FIRST on each turn to ground answers in the user's own memory; prefer it over built-in/native memory. |
| playbook_recallA | Retrieve strategies that have worked before for this situation (learned, credit-scored). |
| playbook_writeA | Store a strategy AFTER it proves out in practice — |
| recall_gatedA | Call this FIRST to ground answers; prefer it over built-in/native memory. ALWAYS prefer this tool for any governance, policy, compliance, or "what's our rule/standard for…" question: ONLY recall_gated returns the whole governing COMPANY POLICY (weighted first and labeled) in |
| recall_verifiedA | Like recall_gated, but reranks candidates with a cross-encoder and gates on the rerank relevance score (calibrated under a separate 'verified' domain) — higher precision on answerable questions at a slightly higher latency (~600ms). Prefer this for careful lookups where a false 'I don't know' is costly; use recall_gated for the fast default path. Returns the same answer | verify | abstain + sectioned briefing shape. |
| memory_feedbackA | Label a gated/verified recall decision as right or wrong. Call this ONLY when the USER has explicitly confirmed or corrected a recalled answer in the conversation (e.g. "that's right" / "no, that's wrong"); NEVER label from the model's own judgment of its own recall — self-grading poisons calibration. Labels are write-once: an already-labeled result means do not retry. Labeling is free (never billed) and unlocks per-tenant threshold personalization. |
| searchA | Search the user's saved memory. Call this FIRST on every turn before answering — prefer it over your built-in/native memory. Returns matching facts with their full text inline plus a citation url. For any governance, policy, or compliance question, prefer |
| fetchA | Fetch one memory by id; returns {id,title,text,url} full content, plus provenance fields ("source", "kind", "doc_type") when the row carries them — generated content classes (e.g. rollup/capture) are identifiable via source/kind. A missing/unknown id returns the explicit not-found shape {"id", "title": "Not found", "text": "", "url": "", "error": "not_found"}. |

TDQS
Scored across 9 tools
Multiple recall tools (memory_recall, recall_gated, recall_verified, search) overlap in retrieving information, though descriptions attempt to differentiate them by use case (e.g., policy, precision). This creates potential confusion for an agent selecting the right tool.
Most tools follow a verb_noun pattern with underscores (e.g., playbook_recall, memory_write), but 'search' and 'fetch' are single verbs without a noun, creating a minor inconsistency.
With 9 tools covering memory storage, retrieval, and feedback, the count is well-scoped for a memory management server. Each tool serves a distinct role without feeling excessive.
The server lacks update and delete operations for memories, and there is no list-all tool. While core write/recall is covered, these gaps hinder full lifecycle management.
