memory_update

Update one or more fields of an existing memory. Use to correct outdated information, promote confidence after confirming an inference, retype a misfiled memory, or add/replace tags. Do not create a new memory when the right action is to update an existing one — find the id first with memory_recall. All fields are optional; only provided fields are changed. ``tags`` (comma-separated) replaces the full tag set when provided — omit to leave tags unchanged. Pass ``metadata=""`` to clear metadata; omit to leave it unchanged. ``type`` retypes the memory (same values as memory_store). Retyping is the right fix when a memory was filed under the wrong kind — e.g. durable reference material saved as ``workflow`` picks up point-in-time review hints, because ``pattern``/``preference`` are the types exempt from them. Retyping does not re-embed: the vector derives from title + content only. ``resolve_claims`` reconciles a stale state claim WITHOUT EDITING THE PROSE — comma-separated refs (e.g. "gingugu#10"), or "all" for every open claim on this memory. Use it when the text is accurate history: a session log that said "PR #10 open" was correct on the day it was written, and rewriting it to stay current destroys the record. The memory body is left byte-identical; only the claim's resolution is recorded. Reach for ``content`` instead only when the memory asserts something that was never true. "all" means every OPEN claim, never an ``unverified`` one. An unverified ref is one the prose names without saying what became of it, so sweeping it under "all" would record that you checked something you did not. Name such a ref explicitly to resolve it — that path works and is the honest way to say "I looked, and it merged". When ``relation_check`` is True (default) and ``title`` or ``content`` was provided, the response includes a ``suggested_relations`` list of up to 3 not-already-linked memories worth examining for a relationship - same semantics as ``memory_store``: overlap is how they were found, and only a directional fact (supersedes / contradicts / caused_by / parent_of / child_of) justifies an edge. Tag-only or confidence-only updates skip the check since the matching surface didn't change. Entries are compact (title + a ~200-char ``summary``) and carry ``similarity`` + ``basis``, as in ``memory_store``; an empty list means nothing was close enough to be worth your time. ``pinned`` marks a memory as ALWAYS loaded by memory_context for its namespace, ahead of and exempt from ranking, in addition to ``limit``. Reserve it for the few rules that would cause real damage if missed — the ones you would want in front of you before touching anything, not merely useful or frequently relevant material. Ranking already handles "relevant"; a pin is for "inviolable". Capped per namespace (currently 20): pinning is a budget, so spending it on a merely-handy memory crowds out a rule that governs behaviour. Pass ``pinned=False`` to unpin. Pinning does not touch ``last_confirmed`` — it is a retrieval decision, not a claim that the content is still true.

memory_forget

Mark a memory as no longer valid or permanently remove it. Default behavior (hard_delete=False) sets confidence to "deprecated", keeping the memory as a historical record but excluding it from future search results by default. Use hard_delete=True only when the memory must be permanently erased (e.g. sensitive data stored by mistake). Prefer deprecation over deletion when in doubt. ``reason`` is optional but recommended for audit trail — recorded in logs.

memory_recall

Search memories by relevance using hybrid BM25 + semantic ranking. Use for natural-language queries when you want the best-matching memories for a topic. Prefer over memory_search when you have a query string and want scored results. Use memory_search instead when you need date filters, type filters, or a specific sort order. ``compact=True`` returns title + a ~200-char ``summary`` instead of full content (related extras included) — the right mode for broad exploratory queries where full bodies would flood the client's tool-result budget. Recall the one or two memories that matter with a targeted follow-up. ``namespace`` accepts a single name or a comma-separated list (e.g. "crow,my-project") to search several namespaces in one ranked pass. Unlike memory_context, ``limit`` is the TOTAL result cap: the best ``limit`` matches across all listed namespaces, not per namespace. A multi-namespace response carries ``namespaces`` and stamps each memory with its source ``namespace``. ``tags`` is comma-separated; ALL provided tags must match. ``confidence`` sets a minimum confidence threshold (verified > inferred > stale > deprecated). ``include_deprecated`` also returns deprecated memories (stale ones are always included). ``include_related`` also surfaces memories directly linked to the top hits via spreading activation: useful for pulling in a related cluster. ``explain=True`` adds a ``score_breakdown`` to each hit: the weighted ``relevance``/``freshness``/``access``/``confidence`` terms that ``score`` is the sum of. Use it to answer "why did this rank here?": a result carried by ``confidence`` and ``freshness`` with a near-zero relevance term matched the query barely or not at all. Off by default because it is a diagnostic, not something worth paying for on every read.

memory_context

Load the most relevant memories for the current session. Call this at session start with a brief description of the current task to prime the agent with useful context. Combines relevance to the task hint with recency, confidence, and access frequency to select the top memories. Also triggers spreading activation to wake related dormant memories. ``namespace`` accepts a single name or a comma-separated list (e.g. "crow,my-project"): a multi-namespace call loads every namespace in one shot and de-duplicates memories that surface in more than one, and each memory is stamped with its source ``namespace``. ``limit`` applies per namespace and defaults to MEMORY_AUTO_CONTEXT_LIMIT (10). ``task_hint`` is a short description of what you are working on (e.g. "fix auth bug") — omit to surface generally high-value memories. ``compact=True`` returns title + a ~200-char ``summary`` instead of full content — pull the full body with memory_recall when a memory matters. Context loads refresh each surfaced memory's dormancy clock but do not count as real accesses: ``access_count`` is reserved for memory_recall/memory_search hits, so protocol-driven session-start loads don't inflate ranking signals. A surfaced memory may carry ``review_hints`` — advisory signals that its content describes point-in-time state (an open PR, a "waiting on" note, a passed expiry date) that hasn't been confirmed recently. Reconcile with memory_update / memory_forget if it's no longer true. ``explain=True`` adds a ``score_breakdown`` to each memory: the weighted terms ``score`` is the sum of, plus ``type_boost`` where the architecture/decision boost applied. It is the way to see which bucket a memory came from: the recency and cross-namespace buckets are scored with a synthetic relevance, so a constant relevance term across several hits means they were selected for recency or reach, not for matching the task hint. Pinned memories carry no breakdown: they never entered the ranking at all.

memory_search

Advanced filtered search across memories with full control over filters and sort order. Use when you need to filter by type, date range, confidence level, or sort by something other than relevance. Prefer memory_recall when you just have a natural-language query and want the best-matching scored results. ``ids`` fetches memories by exact ID (comma-separated, e.g. from a memory_stats review sample) — the precise-fetch path. When given, every other filter is ignored: results come back in the requested order, deprecated memories included (you named them), with a ``missing`` list for any ID not found. All parameters are optional — omitting all returns all memories up to limit. ``namespace`` accepts a single name, a comma-separated list (e.g. "crow,my-project"), or None to search every namespace; ``limit`` is always the total result cap. A multi-namespace response carries ``namespaces`` and stamps each memory with its source ``namespace``. ``tags`` is comma-separated; all provided tags must match. ``sort_by`` is one of: relevance, created, accessed, decay_score. A ``created``/``accessed`` sort orders the whole matching corpus before the limit, so it returns the true newest (or least recently read) rows and narrowing ``limit`` narrows that answer instead of changing it. With a query, that corpus is the keyword match set: a date sort asks something relevance cannot answer, so the semantic cohort does not vote in it and results carry no ``score``. ``confidence`` sets a minimum confidence threshold (verified > inferred > stale > deprecated). ``created_after`` and ``created_before`` accept ISO 8601 date strings (e.g. "2025-01-01"). ``include_deprecated`` also returns deprecated memories (stale ones are always included). ``compact=True`` returns title + a ~200-char ``summary`` instead of full content — the right mode for broad sweeps where full bodies would flood the client's tool-result budget; pull full bodies with a targeted follow-up. ``claims`` restricts results to the reconciliation backlog — memories that still assert a PR/MR is open. "open" is every unresolved claim; "contradicted" narrows to those a later memory in the same namespace has already recorded as resolved, which are answerable immediately from what the brain already holds. Composes with every other filter, so ``claims="open", namespace="gingugu", sort_by="created"`` is a working sweep. Close them out with ``memory_update(resolve_claims=...)``, which records the resolution WITHOUT editing the memory's prose. "unverified" is a different set and NOT a backlog: memories naming a PR/MR whose prose never says what became of it. They assert nothing, so they are absent from every ``open`` count and from ``claims.sample``. Most narrate work that long since shipped — this filter is how you read them, not a queue to work down. Resolve one by naming its ref explicitly; ``resolve_claims="all"`` deliberately leaves them alone. ``orphans=True`` restricts results to memories no relation touches — the graph backlog that ``memory_stats``' ``graph.orphans`` counts. An orphan is reachable only by direct search: spreading activation can never wake it, so a verified, frequently-recalled orphan is retrieval the graph is leaving on the table. Composes with every other filter and works with or without a query, so ``orphans=True, namespace="crow", sort_by="accessed"`` walks the ones costing the most first. Reconnect them with ``memory_relate`` — and only where a directional fact exists to record; an orphan is better left alone than wired up with an invented edge. ``explain=True`` adds a ``score_breakdown`` to each hit: the weighted terms ``score`` is the sum of. Results with no ranking behind them carry none: an ``ids`` fetch and a ``created``/``accessed`` sort were not ranked, and a listing with no query scores every row on the same flat relevance, which the breakdown shows as an identical relevance term.

memory_stats

Return health statistics for the memory store. Use to monitor memory growth, identify dormant memories, and get a per-namespace breakdown of counts and confidence distribution. Call at session start alongside memory_context to assess the state of the knowledge base. ``stats.dormant_count`` reports memories untouched for 90+ days — a resting signal only, never a confidence change. Dormant memories wake automatically on recall via spreading activation. Memory is never auto-forgotten. ``review_limit`` raises the ``review.sample``, ``claims.sample`` and ``graph.orphan_sample`` caps (default 5, max 100) so a reconciliation sweep can enumerate every flagged memory — pair with memory_search's ``ids`` parameter to pull the full bodies. ``stats.graph.orphan_sample`` names the memories behind ``graph.orphans``: those no relation touches, which spreading activation can never reach. Ordered by confidence, then access count, then recency, so the orphans costing the most retrieval come first, each row carrying its ``namespace``. ``memory_search(orphans=True)`` pulls the same set with full bodies; ``memory_relate`` reconnects one — where a directional fact genuinely exists. ``stats.claims`` is the state-claim backlog: memories still asserting a PR/MR is open. ``claims.sample`` enumerates them, contradicted first, each row tagged ``contradicted`` (a later memory in the same namespace already recorded that ref as resolved). ``open`` counts every unresolved claim while ``open_actionable`` — what the sample lists — excludes claims on deprecated memories. ``memory_search(claims="open")`` pulls the same set with full bodies; ``memory_update(resolve_claims=...)`` closes them without editing prose. ``claims.unverified`` counts refs a memory names without ever saying what became of them. It is reported for visibility, not action: those refs assert nothing, so they are excluded from ``open`` and from ``sample`` on purpose. Read them with ``memory_search(claims="unverified")``. ``flag_stale`` is deprecated and ignored — auto-demotion to stale contradicted the never-forget model and has been removed. Retained so existing callers do not error. ``namespace`` scopes the stats to a single namespace; omit for global.

memory_excerpt

Search or slice WITHIN one memory's body, without loading the whole thing. Recall and search answer "which memory?"; this answers "where in it?". Between a full body and a ~200-char compact summary there was nothing: asking whether a long memory mentions a particular decision, and where, meant pulling every byte of it into context. Use this instead once you know which memory you want. Two modes, composable: - **Find**: pass ``query`` for a literal, case-insensitive substring scan. Each match returns its ``start``/``end`` character offsets, its 1-indexed ``line``, and an ``excerpt`` with ``context_chars`` of surrounding text on each side. ``total_matches`` is the true count even when ``max_matches`` caps what comes back, so you can tell "that was all of them" from "that was the first 10 of 300". - **Slice**: pass ``start`` and/or ``end`` character offsets to read an exact range. Omitted bounds mean start-of-body and end-of-body. Feed back the offsets from a find to read the full passage around a hit. Passing both searches only inside the range, with offsets still reported absolute against the full body. The scan is literal and deterministic: no ranking, no stemming, no model. Asking twice gives the same answer in the same order, and matches come back in the order they appear in the text, never by relevance. ``length`` (total characters) and ``lines`` come back on every call, so a first call with no query is a cheap way to size a memory before deciding how to read it. Reading a memory this way credits it as a real access, the same as naming it in ``memory_search(ids=...)``.

memory_relate

Create a directional link between two memories. Relations are used by spreading activation (recalling one memory wakes its related cluster) and are returned when include_related=True in memory_recall. **An edge must encode something search cannot infer.** Recall already ranks by hybrid text + semantic similarity, so "these two memories are about the same topic" is knowledge the index has for free. What only a relation can record is direction and time: which memory REPLACED which, what CAUSED what, what CONTRADICTS what, what CONTAINS what. Prefer, in this order: ``supersedes``, ``contradicts``, ``caused_by``, ``parent_of``/``child_of``. Reach for ``related_to`` only when a genuine connection exists that none of those describe - it is the fallback, not the default. Quality over volume: spreading activation surfaces at most 3 neighbours per seed memory, and it weights by relation type - a directional edge outranks ``related_to``, so on any memory with more than 3 edges the ``related_to`` ones are what lose their slot. A vague edge is therefore not merely low-value, it is likely to never fire at all; and precise edges still compete against each other for those 3 slots, so a handful of them retrieves better than a dense mesh. If you cannot name the directional fact an edge records, do not create it. A mislabelled edge is repairable: ``memory_unrelate`` retypes or removes one. ``source_id`` is the memory making the claim about ``target_id``. ``relation_type`` must be one of: supersedes (source replaces target), contradicts (conflicting claims), caused_by (source was caused by target), parent_of (source contains target), child_of (source belongs to target), related_to (fallback: a real connection none of the above captures).

memory_edges

Enumerate graph edges with both endpoints resolved to titles. Read-only. ``memory_stats`` reports that the graph is, say, 70% ``related_to`` — this is how you see WHICH edges those are, in order to judge them. Pair it with ``memory_unrelate`` to run a repair sweep: enumerate a page, decide each edge on its merits, submit the batch, advance ``offset``. Each row carries both endpoints' ids, titles and namespaces, the relation type, and each endpoint's ``degree`` (total edges touching it). Degree is the one that decides reachability: spreading activation visits at most 3 neighbours per seed, so edges on a high-degree memory may never fire. It ranks candidates by confidence then relation type, so the ones dropped there are ``related_to`` first - which is what makes a high-degree, mostly-``related_to`` memory the best target for a repair sweep. ``namespace`` matches an edge when **either** endpoint lives there, since relations legitimately cross namespaces. ``relation_type`` filters to one type (``related_to`` is the usual repair target). ``memory_id`` returns every edge touching one memory, in either direction. Ordering is stable, so a paged sweep sees each edge exactly once — but note that repairing edges as you page changes what matches, so re-run from ``offset=0`` when filtering on a type you are actively retyping away from.

memory_unrelate

Repair the graph: retype a mislabelled edge, turn a backwards one around, or remove one that should not exist. The counterpart to ``memory_relate`` — without it, an edge written in haste is permanent, and every wrong edge keeps competing for one of the 3 spreading-activation slots on its memories forever. **Retype** by passing ``new_relation_type`` alongside ``relation_type``. The edge is relabelled in place: direction, creation time and metadata survive, because the usual repair is "right connection, wrong label" and the graph should keep an honest record of when the link was first drawn. If an edge of the new type already joins the pair, the two collapse into one and the outcome reports ``merged`` rather than ``retyped`` — the edge count drops by one, and nothing is fabricated to hide that. **Reverse** by passing ``reverse=True`` alongside ``relation_type``. The endpoints are swapped on the same row, so id, creation time and metadata survive exactly as they do for a retype — the connection was right, only the arrow pointed the wrong way. Reversing COMBINES with ``new_relation_type``, in one write, because an edge recorded backwards is often mislabelled as well. Note that reversing ``parent_of``/``child_of`` is the same operation as flipping between the two types: do one or the other, not both. As with a retype, an existing edge in the target direction absorbs this one and reports ``merged``. **Delete** by omitting ``new_relation_type`` and ``reverse``. With ``relation_type``, only that edge goes; without it, every edge from ``source_id`` to ``target_id`` goes, whatever the type. Deletion here is not the bulk prune the graph guidance warns against: the caller names each edge, exactly as ``memory_forget`` names a memory. **Batch** by passing ``edges`` — an array of up to 100 objects, each with ``source_id``, ``target_id`` and optionally ``relation_type`` / ``new_relation_type`` / ``reverse``, i.e. the same decision made once per edge: [{"source_id": "a", "target_id": "b", "relation_type": "related_to", "new_relation_type": "caused_by"}, {"source_id": "c", "target_id": "d", "relation_type": "caused_by", "reverse": true}, {"source_id": "e", "target_id": "f", "relation_type": "related_to"}] A batch is reviewed decisions submitted together, NOT a criteria-driven sweep, and that is deliberate. There is no "retype every ``related_to`` in this namespace" option, because the whole point of retyping is that each edge deserves a different type based on what it actually records — a blanket relabel would manufacture directional claims that were never true, and a false ``caused_by`` is worse than an honest ``related_to``. The batch is validated in full before anything is written, so a malformed op fails the whole call rather than leaving the graph half-repaired. Individual outcomes (``retyped``, ``reversed``, ``merged``, ``deleted``, ``not_found``, ``unchanged``) are reported per edge. Use ``dry_run=True`` to preview a sweep first; nothing is written and each op reports what it would have done. Find the edges to repair with ``memory_edges``.

memory_consolidate

Combine multiple memories into one to reduce redundancy and knowledge bloat. Use when several related memories about the same topic have accumulated over time. Do not use on memories that are still actively distinct — prefer memory_relate to link them instead. ``memory_ids`` is comma-separated (minimum 2 ids required). ``strategy`` is one of: merge (concatenate all content into one memory), summarize (produce a condensed combined summary), deduplicate (keep the highest-confidence entry and deprecate the rest). ``keep_originals=True`` (default) preserves originals as deprecated; set False to hard-delete them. **Suggest mode:** omit ``memory_ids`` entirely for a read-only near-duplicate scan of ``namespace`` (or the resolved default). Returns candidate clusters found by pairwise embedding similarity at or above ``min_similarity`` (falls back to exact-title clusters when embeddings are absent or sparse). Nothing is written — inspect the clusters, then call again with ``memory_ids`` to actually consolidate. An empty ``memory_ids`` string is still an error, so a caller that built its id list from an empty collection fails loudly.
