Fulcra Memory

Fulcra Agent Memory Sync

The primary role of this skill is to help the agent keep track of what it is doing in a readable and transferable way using Fulcra's versioned file storage, strictly following the Open Knowledge Format (OKF).

By periodically logging activities to progress.md and keeping the memory namespace structured, other agents and users can easily see what this agent has accomplished and what it is working on next.

(Note: For agent backup, rollback, and cloning, see the fulcradynamics/agent-skills/fulcra-agent-backup skill.)

Primary Role: Progress & OKF Compliance

1. The Memory Namespace (OKF Compliant)

For core memory tracking, agents use the standardized prefix: agent/<lowercase-agent-name>/. This dedicated directory tracks the agent's state. It must conform to the Open Knowledge Format (OKF), meaning it contains an index.md, a log.md, and markdown concept files like progress.md.

IMPORTANT OKF EFFICIENCY DIRECTIVE: While OKF compliance is mandatory, it must not become cumbersome.

• DO NOT attempt to index every individual file, especially not transient or highly repetitive files like individual messages inside an inbox/ subdirectory.
• For directories that contain many small or transient items (like an inbox/ or queue/), simply list the directory itself in the index.md with a high-level description of its purpose (e.g., "Contains unread messages from the web dashboard").
• Keep the index.md and log.md focused on top-level structure and significant milestones (like the progress.md) so they remain useful but lightweight.

2. Discovering Recent Memory Changes

Rather than exhaustively querying your namespace to remember what you or others recently learned, use the Fulcra API's data-updates command (e.g., uv tool run fulcra-api data-updates "1 day"). This will return a summary of all files that changed recently, allowing you to easily see what knowledge was added and which memory files were updated across your local and team-shared namespaces.

3. Progress Reports

Agents should run a progress sync periodically (e.g., triggered by HEARTBEAT.md). Every time an agent syncs its state:

1. It writes a concise progress.md report locally—summarizing the work it has recently done, and what it is planning to do next—and uploads it directly to agent/<agent-name>/progress.md. The progress.md file must include proper OKF YAML frontmatter (with type: Progress Report). This file is a report specifically designed to let the user review the agent's recent accomplishments and intended next steps. It is not intended to dump internal agent state, chain-of-thought, or precise working memory.
2. It updates the log.md (Update History) and ensures the index.md directory listing is accurate.

PRIVACY REQUIREMENT: Before uploading progress.md, the agent MUST ensure it is not inadvertently uploading new sensitive personal user data, credentials, or private internal reasoning. Minimize disclosures in progress.md.

4. Agent Identity & Role

The role.md file defines the agent's high-level purpose, duties, identity, and standard operating procedures.

• It resides at agent/<agent-name>/role.md.
• The agent is responsible for keeping this file up to date so that the user and other agents understand what this agent does and how it operates.
• It must include OKF YAML frontmatter (type: Role).
• Upload this directly to agent/<agent-name>/role.md.

5. Session Summaries

The session/ subdirectory is used to record high-level summaries of what was accomplished during a specific spate of work or interaction.

• When a work session concludes, or when asked to remember context, the agent writes a summary to a file in memory/session/.
• Session files MUST be prefixed with a timestamp in the format YYYYMMDD-HHMMSS followed by an underscore and a short subject (e.g., YYYYMMDD-HHMMSS_setup-dashboard.md).
• These files serve as targeted, easily-retrievable context. They should capture decisions made, important links, user preferences discovered, and the final state of the session.
• Ensure the session/ directory is listed in the top-level index.md with a high-level description. You do not need to index every individual session file in index.md.
• Upload these session files directly to agent/<agent-name>/session/<filename>.md.

6. Long-Running Tasks

The task/ subdirectory is dedicated to longer-running tasks that span multiple sessions or interactions.

• Create a file in memory/task/ for any significant ongoing project or objective.
• Task files must NOT be prefixed with a timestamp. They should simply be named for the task (e.g., memory/task/setup-dashboard.md).
• These files track the overall purpose, current state, and result of the task. They should be updated periodically by the agent as work progresses.
• Task files should contain references to any relevant artifacts and session files related to the task.
• Unlike session files, task files MUST be included in the memory/task/index.md file, which should list all active and completed tasks in the directory.

7. General Knowledge Base

The knowledge/ subdirectory is an open-ended convention for agents to store, organize, and retrieve any other useful knowledge or reference material about the user, the agent's domain, or specific topics.

• Because each user has different interests and requirements, this directory acts as a flexible knowledge base.
• Files should be structured according to the OKF standard (using index.md files for subdirectories to aid in navigation and discovery).
• Knowledge files can be organized by topic, entity, or domain (e.g., memory/knowledge/programming/python.md or memory/knowledge/user-preferences/formatting.md).
• Ensure the knowledge/ directory is listed in the top-level index.md so that the user and other agents know it exists.
• This convention empowers agents to build a rich, personalized context over time without being artificially limited by standard tracking conventions.

8. Personal Inbox

The inbox/ subdirectory (agent/<agent-name>/inbox/) is used for asynchronous communication directed specifically to the agent (from users or other automated, non-team sources).

• To make it easy for users to manually drop files into the inbox, files placed here DO NOT need to adhere to a strict timestamp or subject naming convention (e.g., a user might just drop a file named todo.md).
• When the agent reads an inbox message and decides to archive it, it moves the file to the archive/ directory.
• If the original file name does not already start with a timestamp, the agent MUST prepend a timestamp (YYYYMMDD-HHMMSS_) to the filename when saving it to archive/ (e.g., archiving todo.md becomes archive/20260624-153000_todo.md). This ensures the archive remains chronologically sortable even for manually dropped files.
• Remember, as per the OKF Efficiency Directive, you do not need to log every individual inbox or archive file in index.md.

Workflow

To perform memory tracking operations, agents should prefer using the Fulcra CLI, though Fulcra MCP tools are fully supported as an alternative.

For general information about the Fulcra File Store and the required Open Knowledge Format (OKF) standard, please refer to the main Fulcra CLI documentation found in the fulcradynamics/agent-skills/fulcra-get-started skill, or read the full OKF specification directly:

• Read references/fulcra-memory-mcp.md if using the MCP alternative.
