API Reference

AgentMemory

The primary interface for reading, writing, and managing agent memory.

Constructor

AgentMemory(
    agent_id: str,
    *,
    session_id: str | None = None,
    config_path: Path | None = None,
    adapter: AdapterABC | None = None,
    ttl_sweep_interval: float | None = None,
    decay_half_life_days: float | None = None,
    embedder: EmbedderABC | None = None,
    importance_evaluator: ImportanceEvaluator | None = None,
    conflict_policy: ConflictPolicy = ConflictPolicy.LAST_WRITE_WINS,
    on_conflict: Callable | None = None,
)

Parameter	Type	Default	Description
`agent_id`	`str`	required	Unique identifier for this agent
`session_id`	`str?`	auto-generated	Session ID for provenance
`config_path`	`Path?`	auto-discovered	Path to `amfs.yaml`
`adapter`	`AdapterABC?`	from config	Pre-configured adapter
`ttl_sweep_interval`	`float?`	`None`	Seconds between TTL sweeps
`decay_half_life_days`	`float?`	`None`	Confidence decay half-life
`embedder`	`EmbedderABC?`	`None`	Embedder for semantic search
`importance_evaluator`	`ImportanceEvaluator?`	`None`	Scores entries on write (sets `importance_score` and `importance_dimensions`)
`conflict_policy`	`ConflictPolicy`	`LAST_WRITE_WINS`	Concurrent write strategy
`on_conflict`	`Callable?`	`None`	Custom conflict resolver

read

read(
    entity_path: str,
    key: str,
    *,
    min_confidence: float = 0.0,
    branch: str = "main",
) -> MemoryEntry | None

Returns the current version of the entry, or None if not found or below confidence threshold. The branch parameter selects which branch to read from (defaults to main).

write

write(
    entity_path: str,
    key: str,
    value: Any,
    *,
    confidence: float = 1.0,
    ttl_at: datetime | None = None,
    pattern_refs: list[str] | None = None,
    memory_type: MemoryType = MemoryType.FACT,
    artifact_refs: list[ArtifactRef] | None = None,
    shared: bool = True,
    branch: str = "main",
) -> MemoryEntry

Creates a new version of the entry. If the key already exists, the previous version is superseded (CoW). The memory_type parameter controls decay behavior — belief decays 2× faster, experience decays 1.5× slower. The branch parameter determines which branch the entry is written to (defaults to main). Every write is also logged as an event on the agent’s git-like timeline. The optional artifact_refs parameter links external blobs (S3 objects, files, URLs) to this entry. See ArtifactRef below.

list

list(
    entity_path: str | None = None,
    *,
    include_superseded: bool = False,
    branch: str = "main",
) -> list[MemoryEntry]

Returns all current entries, optionally filtered by entity. Set include_superseded=True for full version history. The branch parameter selects which branch to list from.

search

search(
    *,
    query: str | None = None,
    entity_path: str | None = None,
    entity_paths: list[str] | None = None,
    min_confidence: float = 0.0,
    max_confidence: float | None = None,
    agent_id: str | None = None,
    since: datetime | None = None,
    pattern_ref: str | None = None,
    sort_by: str = "confidence",
    limit: int = 100,
    depth: int = 3,
    recall_config: RecallConfig | None = None,
) -> list[MemoryEntry] | list[ScoredEntry]

Search across all entries with rich filters. depth controls progressive retrieval: 1 = Hot tier only, 2 = Hot + Warm, 3 = all tiers (default). When query is provided, the text is forwarded to the adapter for full-text search (Postgres tsvector). When recall_config is also set, returns ScoredEntry objects sorted by composite recall score with a breakdown dict.

Behavior	`query` set	`query` not set
Postgres adapter	tsvector `@@` filter + `ts_rank` ordering	standard SQL filter
Filesystem/S3 adapter	Python substring fallback	standard filter
With `recall_config`	Real cosine similarity in semantic component	Semantic component is 0.0

graph_neighbors

graph_neighbors(
    entity: str,
    *,
    relation: str | None = None,
    direction: str = "both",
    min_confidence: float = 0.0,
    depth: int = 1,
    limit: int = 50,
) -> list[GraphEdge]

Traverse the knowledge graph from an entity. Returns edges connecting the entity to other entities, agents, and outcomes. Multi-hop traversal is supported via depth > 1 (Postgres adapter uses recursive CTE). The Filesystem and S3 adapters return an empty list.

Parameter	Description
`entity`	Entity to explore (e.g. `"checkout-service/retry-pattern"`)
`relation`	Filter by relation type (e.g. `"references"`, `"informed"`, `"learned_from"`)
`direction`	`"outgoing"`, `"incoming"`, or `"both"`
`depth`	Traversal depth (1 = direct neighbors)

timeline

timeline(
    *,
    branch: str | None = None,
    event_type: str | None = None,
    since: datetime | None = None,
    limit: int = 100,
) -> list[Event]

Returns the git-like event log for this agent. Every write, outcome, cross-agent read, and brain brief is recorded as an event. See Git-like Timeline for details.

semantic_search

semantic_search(
    text: str,
    *,
    top_k: int = 10,
) -> list[tuple[MemoryEntry, float]]

Search by meaning using vector similarity. Requires an embedder to be configured.

watch

watch(
    entity_path: str,
    callback: Callable[[MemoryEntry], None],
) -> WatchHandle

commit_outcome

commit_outcome(
    outcome_ref: str,
    outcome_type: OutcomeType,
    causal_entry_keys: list[str] | None = None,
    *,
    causal_confidence: float = 1.0,
    decision_summary: str | None = None,
) -> list[MemoryEntry]

Record an outcome and update confidence on causal entries. If causal_entry_keys is None, uses auto-causal linking (all entries read in this session). The optional decision_summary parameter adds a human-readable description of the decision to the persisted trace. When called, the trace automatically captures:

Causal entry snapshots with full value, memory_type, written_by, and read_at timestamps
Query events from all search() and list() calls during the session, with parameters, result counts, and per-operation latency
Error events from any failed operations
Session timing — session_started_at, session_ended_at, session_duration_ms
State diff — entries created, updated, and confidence changes

history

history(
    entity_path: str,
    key: str,
    *,
    since: datetime | None = None,
    until: datetime | None = None,
) -> list[MemoryEntry]

Returns all versions of an entry, optionally filtered by time range. Entries are sorted by version ascending.

record_context

record_context(
    label: str,
    summary: str,
    *,
    source: str | None = None,
) -> None

Record external context (tool call, API response, database query) in the causal chain without writing to storage. These appear in the external_contexts field of explain() output, making decision traces complete.

explain

explain(
    outcome_ref: str | None = None,
) -> dict[str, Any]

Returns the causal chain for the current session: which AMFS entries were read, which external contexts were recorded, and their details. If outcome_ref is provided, labels the explanation with that reference. Returns:

{
    "outcome_ref": str | None,
    "agent_id": str,
    "session_id": str,
    "causal_chain_length": int,
    "causal_entries": list[dict],       # AMFS entries that were read
    "external_contexts": list[dict],    # tool/API inputs via record_context()
}

briefing

briefing(
    entity_path: str | None = None,
    agent_id: str | None = None,
    limit: int = 10,
) -> list[Digest]

Get a ranked briefing of compiled knowledge digests from the Memory Cortex. Returns pre-compiled Digest objects ranked by relevance to the given entity or agent context. If no Cortex is running, returns an empty list.

ArtifactRef

Link memory entries to external blobs — model weights, datasets, logs, screenshots, or any binary artifact stored outside AMFS.

class ArtifactRef:
    uri: str                    # S3 URI, file path, or URL
    media_type: str | None      # MIME type (e.g. "application/json")
    label: str | None           # Human-readable label

            size_bytes=1_500_000_000,
        ),
    ],
)

Provenance

    # Legacy aliases (deprecated — will be removed in a future version)
    P1_INCIDENT = "critical_failure"
    P2_INCIDENT = "failure"
    REGRESSION = "minor_failure"
    CLEAN_DEPLOY = "success"

MemoryType

class MemoryType(str, Enum):

    EXPERIENCE = "experience"  # Action log, 1.5× slower decay

ProvenanceTier

class ProvenanceTier(int, Enum):
    PRODUCTION_VALIDATED = 1   # Production agent + outcomes applied
    PRODUCTION_OBSERVED = 2    # Production agent, no outcomes yet
    DEVELOPMENT = 3            # Dev/test environment
    MANUAL = 4                 # Manually seeded

ConflictPolicy

class ConflictPolicy(str, Enum):
    LAST_WRITE_WINS = "last_write_wins"
    RAISE = "raise"

RecallConfig

class RecallConfig:
    semantic_weight: float = 0.5   # Cosine similarity (requires embedder)
    recency_weight: float = 0.3    # Exponential decay by age
    confidence_weight: float = 0.2 # Entry confidence score

ScoredEntry

class ScoredEntry:
    entry: MemoryEntry
    score: float                # Composite recall score
    breakdown: dict[str, float] # Per-signal contributions

from amfs_core.importance import ImportanceEvaluator, NoOpEvaluator

class ImportanceEvaluator(ABC):
    def evaluate(self, entity_path: str, key: str, value: Any) -> tuple[float | None, dict[str, float]]:
        """Returns (overall_score, dimension_breakdown)."""

class NoOpEvaluator(ImportanceEvaluator):
    """Returns (None, {}) — zero overhead. Used by default."""

Pass a custom evaluator to AgentMemory(importance_evaluator=...) to score entries on write. The Pro edition provides LLMImportanceEvaluator with 3-dimension scoring.

AdapterABC (new methods)

def increment_recall_count(self, entity_path: str, key: str, *, branch: str = "main") -> None:
    """In-place update — does NOT create a new CoW version."""

def update_tiers(self, updates: list[tuple[str, str, int, float]], *, branch: str = "main") -> None:
    """Batch update (entity_path, key, tier, priority_score) tuples."""

GraphEdge

class GraphEdge:

    evidence_count: int    # Times this edge has been reinforced
    first_seen: datetime
    last_seen: datetime
    provenance: dict | None

Graph edges are materialized automatically:

Trigger	Edge created
`write(pattern_refs=["x"])`	`entry → references → x`
`commit_outcome()`	`entry → informed → outcome`, `agent → read → entry`, co-occurrence edges
`read_from(agent_id)`	`this_agent → learned_from → other_agent`

GraphNeighborQuery

class GraphNeighborQuery:
    entity: str
    relation: str | None = None
    direction: str = "both"   # "outgoing", "incoming", "both"

    staleness_ms: int                   # Age since compilation (set at query time)
    anticipation_score: float           # Outcome-calibrated relevance (0.0–1.0)
    namespace: str                      # Memory namespace

MemoryStats

class MemoryStats:
    total_entries: int
    total_outcomes: int

MCP Tools

When used via MCP, the following tool signatures are exposed:

amfs_read

amfs_read(entity_path: str, key: str) -> str (JSON)

amfs_write

amfs_write(
    entity_path: str,
    key: str,
    value: str,
    confidence: float = 1.0,
    pattern_refs: list[str] | None = None,
    memory_type: str = "fact",  # "fact" | "belief" | "experience"
    artifact_refs: list[dict] | None = None,
) -> str (JSON)

value is passed as a string. If it’s valid JSON, it’s parsed automatically; otherwise stored as a plain string.

Each item in artifact_refs should be a dict with uri (required), and optionally media_type, label, and size_bytes.

amfs_search

amfs_search(
    query: str | None = None,
    entity_path: str | None = None,
    min_confidence: float = 0.0,
    agent_id: str | None = None,
    sort_by: str = "confidence",
    limit: int = 20,
    depth: int = 3,
) -> str (JSON)

depth controls progressive retrieval: 1 = Hot only, 2 = Hot + Warm, 3 = all (default).

amfs_list

amfs_list(entity_path: str | None = None) -> str (JSON)

amfs_stats

amfs_stats() -> str (JSON)

amfs_commit_outcome

amfs_commit_outcome(
    outcome_ref: str,
    outcome_type: str,  # "critical_failure" | "failure" | "minor_failure" | "success" (legacy: "p1_incident" | "p2_incident" | "regression" | "clean_deploy")
) -> str (JSON)

amfs_record_context

amfs_record_context(
    label: str,
    summary: str,
    source: str = "",
) -> str (JSON)

Record external context (tool call, API response) in the causal chain. Appears in amfs_explain() output.

amfs_history

amfs_history(
    entity_path: str,
    key: str,
    since: str | None = None,  # ISO 8601 datetime
    until: str | None = None,  # ISO 8601 datetime
) -> str (JSON)

Returns all versions of an entry, optionally bounded by a time range. Dates are ISO 8601 strings.

amfs_explain

amfs_explain(
    outcome_ref: str | None = None,
) -> str (JSON)

Returns the causal read chain for the current session: which entries were read and their details.

amfs_retrieve

amfs_retrieve(
    query: str,
    entity_path: str | None = None,
    min_confidence: float = 0.0,
    limit: int = 10,
    semantic_weight: float = 0.5,
    recency_weight: float = 0.3,
    confidence_weight: float = 0.2,
) -> str (JSON)

Find the most relevant memories for a natural language query. Blends semantic similarity, recency, and confidence into a single ranked list. Returns ScoredEntry-shaped results with score breakdowns. Requires an embedder for the semantic signal; without one, ranking uses recency and confidence only.

amfs_graph_neighbors

amfs_graph_neighbors(
    entity: str,
    relation: str | None = None,
    direction: str = "both",
    min_confidence: float = 0.0,
    depth: int = 1,
    limit: int = 50,
) -> str (JSON)

Explore the knowledge graph around an entity. Returns edges with relation types, confidence, and evidence counts. Use depth > 1 for multi-hop traversal (Postgres adapter only).

amfs_timeline

amfs_timeline(
    agent_id: str | None = None,
    branch: str | None = None,
    event_type: str | None = None,
    since: str | None = None,
    limit: int = 100,
) -> str (JSON)

Returns the git-like event log for an agent. Every write, outcome, cross-agent read, and brain brief is recorded as an event. See Git-like Timeline.

amfs_critique() -> str (JSON)

Run the Memory Critic to detect toxic, stale, contradictory, uncalibrated, and orphaned entries.

amfs_briefing

amfs_briefing(
    entity_path: str | None = None,
    agent_id: str | None = None,
    limit: int = 10,
) -> str (JSON list of Digest objects)

Get a compiled knowledge briefing — what you should know right now. Returns pre-compiled digests from the Memory Cortex ranked by relevance. Includes entity summaries, agent brain briefs, and external source summaries.

amfs_distill

amfs_distill(
    min_confidence: float = 0.3,
    max_entries: int = 500,
) -> str (JSON)

Generate a distilled memory set for bootstrapping new agents.

amfs_validate

amfs_validate(
    entity_path: str,
    key: str,
    value: str,
    confidence: float = 1.0,
    memory_type: str = "fact",
) -> str (JSON)

Validate a proposed memory write against safety checks (contradiction detection, temporal consistency, confidence thresholds).

amfs_retrieve

amfs_retrieve(
    query: str,
    entity_path: str | None = None,
    min_confidence: float = 0.0,
    limit: int = 10,
    depth: int = 3,
) -> str (JSON)

Multi-strategy retrieval combining semantic, keyword, temporal, confidence, and learned ranking signals via Reciprocal Rank Fusion. depth controls tier scope (same as amfs_search). When a learned model is trained (via amfs_retrain), it automatically contributes to ranking.

amfs_retrain

amfs_retrain(
    entity_path: str | None = None,
) -> str (JSON)

Train (or retrain) the learned ranking model from outcome data. Requires at least 20 outcome-linked entries. Returns training metrics including accuracy, sample counts, and feature importances. Once trained, the model enhances amfs_retrieve results automatically.

amfs_calibrate

amfs_calibrate(
    entity_path: str | None = None,
    per_entity: bool = false,
) -> str (JSON)

Learn optimal confidence multipliers from historical outcome data. Returns calibrated multipliers and estimated decay half-life. Set per_entity=true to also produce entity-specific overrides.

amfs_export_training_data

amfs_export_training_data(
    format: str = "sft",
    entity_path: str | None = None,
    limit: int = 10000,
) -> str (JSON)

Export decision traces as fine-tuning datasets. Format options: "sft" (supervised fine-tuning), "dpo" (direct preference optimization), "reward_model" (reward model training). See the ML Layer guide for format details.

amfs_record_llm_call

amfs_record_llm_call(
    model: str,
    provider: str = "",
    prompt_tokens: int = 0,
    completion_tokens: int = 0,
    latency_ms: float = 0,
    cost_usd: float = 0,
    temperature: float | None = None,
    max_tokens: int | None = None,
    finish_reason: str | None = None,
    error: str | None = None,
) -> str (JSON)

Record an LLM call in the current decision trace. Captures model, provider, token counts, cost, latency, and sampling parameters. Aggregated as total_llm_calls, total_tokens, and total_cost_usd in the trace.
