AGENT DIRECTIVE - SESSION INITIALIZATION: Call this tool FIRST when starting work or opening a project session to retrieve the last recorded session checkpoint ('system/last_memory') and understand where work was left off.

Parameters: project_root: REQUIRED. Absolute path to active project root directory. namespace: Logical namespace (default: 'default').

AGENT DIRECTIVE - MILESTONE & SESSION CHECKPOINTING: Call this tool whenever completing a milestone, making key project changes, or pausing work to update the canonical project checkpoint ('system/last_memory') so future sessions know where work was left off.

Parameters: content: Brief note or structured dictionary summarizing progress and referencing key memory files (e.g. 'Goal Progress'). project_root: REQUIRED. Absolute path to active project root directory. namespace: Logical namespace (default: 'default'). summary: Optional one-sentence description of the milestone achieved.

Stores or updates a persistent memory record in Open Knowledge Format (OKF v0.2).

Parameters: key: Unique identifier or path for the memory (e.g. 'user/preferences/coding_style' or 'system/last_memory'). content: The core information to store (string text or structured dictionary). project_root: REQUIRED. Absolute path to active project root directory. tags: Optional classification tags for filtering (e.g. ['preferences', 'user']). namespace: Logical separation for contexts or users (default: 'default'). concept_type: OKF concept type (default: 'Agent Memory'). Options: 'Agent Memory', 'Checkpoint', 'Metric', 'Playbook', etc. title: Human-readable display name. description: Single-sentence summary of the concept. resource: Canonical URI for the underlying asset. status: Lifecycle status ('draft' | 'stable' | 'deprecated'). Default: 'stable'. stale_after: ISO date ('YYYY-MM-DD') when memory becomes stale. sources: Provenance sources list [{resource, id, title, author, usage_count, last_modified}]. usage_window: Sources usage window framing {from, to}. verified: Verification events list or mapping [{by, at}]. generated_by: Actor identifier string following actor convention ('/', 'human:', 'process:'). runtime: For Attested Computation concepts ('bigquery', 'postgres', 'dbt', 'python'). parameters: For Attested Computation concepts [{name, type, required}]. executor: For Attested Computation concepts {resource, receipt}. attester: For Attested Computation concepts {resource}. computation: Path to external computation file.

Retrieves a specific memory record by key.

Parameters: key: The exact memory key to look up (e.g. 'system/last_memory' for session checkpoint). project_root: REQUIRED. Absolute path to active project root directory. namespace: Logical namespace (default: 'default').

Searches persistent memories matching keywords, tags, or namespace patterns.

Parameters: project_root: REQUIRED. Absolute path to active project root directory. query: Search string for full-text search across keys, frontmatter, and content. tags: Optional list of tags to filter by. namespace: Optional namespace filter. limit: Maximum number of results to return (default: 10).

Removes a specific memory entry.

Parameters: key: The key of the memory to remove. project_root: REQUIRED. Absolute path to active project root directory. namespace: Logical namespace (default: 'default').
