description	Persistent memory and context for AI agents using Cognis by Lyzr. Use this skill when the user mentions "remember this", "what did I work on", "save this for later", "team knowledge", "project context", "recall", "memory", or needs long-term memory across sessions. Also use when the user asks about past decisions, preferences, or prior conversations. Supports personal memory (per-user), team memory (shared across repo contributors), semantic search, and automatic context assembly.

Cognis — Persistent Memory for AI Agents

Cognis gives you long-term memory that persists across sessions. Memories are scoped per-user and per-project, with optional team-wide sharing.

Setup

The LYZR_API_KEY environment variable must be set. Get a key at studio.lyzr.ai.

export LYZR_API_KEY="your-key-here"

Optionally set COGNIS_OWNER_ID to override the default owner (system username).

Scoping

Cognis uses two levels of scoping to keep memories organized:

• owner_id: Identifies the user. Defaults to the system username (whoami). Override with COGNIS_OWNER_ID.
• agent_id: Identifies the project context.
  • Personal scope: claudecode_<sha256(git_root)[:16]> — unique per user per project.
  • Team scope: repo_<sanitized_repo_name> — shared across all contributors to a repo.

The scripts detect the git root and remote automatically. No manual configuration needed.

Saving Memories

Save something the user wants to remember:

bash scripts/cognis-save.sh "The user prefers PostgreSQL for all new services"

Save a team-wide memory (visible to all repo contributors):

bash scripts/cognis-save.sh "Deploy process: run migrations first, then deploy API, then workers" --team

Read references/api-reference.md for full parameter details.

Searching Memories

Search for relevant memories:

bash scripts/cognis-search.sh "what database do we use"

Search only team memories:

bash scripts/cognis-search.sh "deployment process" --repo

Search both personal and team:

bash scripts/cognis-search.sh "auth setup" --both

Getting Assembled Context

Fetch relevant context (combines short-term and long-term memory):

bash scripts/cognis-context.sh

This returns assembled context for the current project, including relevant personal and team memories.

When to Use Personal vs Team Scope

• Personal (default): User preferences, individual notes, personal workflow details, things the user says about themselves.
• Team (--team): Architecture decisions, deployment processes, coding conventions, shared knowledge that any contributor would benefit from.

Gotchas

• Memories are extracted asynchronously by default. Use the search endpoint to verify a memory was stored (it may take a few seconds).
• The LYZR_API_KEY must have access to the Cognis memory service. If you get 401/403 errors, read references/quickstart.md for troubleshooting.
• Scripts output JSON to stdout and diagnostics to stderr. Parse stdout for programmatic use.
• All scripts are idempotent — safe to retry on transient failures.

Available Scripts

• scripts/cognis-save.sh — Save a memory (personal or team scope). Run bash scripts/cognis-save.sh --help for usage.
• scripts/cognis-search.sh — Search memories with semantic matching. Run bash scripts/cognis-search.sh --help for usage.
• scripts/cognis-context.sh — Get assembled context for the current project. Run bash scripts/cognis-context.sh --help for usage.
