Facts.
Architecture, module boundaries, file landmarks, commands, services, and conventions that should not be rediscovered every session.
Memory
It remembers.
The codebase. Your style. The decisions. The failures. The reasons. Retrieved before work starts, injected when relevant, and visible under your control.

What it keeps.
Style.
How you test, name, import, review, and ship, so repeated work keeps the same shape.
Decisions.
The reason a migration, dependency, constraint, or tradeoff happened, preserved for the next canvas.
Failures.
Test failures, rejected fixes, repeated loops, and avoid-next-time notes that help the agent stop making the same mistake.
Workflow.
Repo rules, preferred commands, onboarding notes, and model-performance observations for the current workspace.
How it comes back.
Before planning, Picasso loads the structured memory store, retrieves relevant account, workspace, repo, pinned, and stale-but-useful records, and injects the selected context into the provider messages. The agent gets targeted memory without flooding the prompt or pretending old chat history is understanding.

How it writes back.
After a run, Picasso summarizes what happened, classifies useful lessons, filters secrets and private values, and writes structured fact, style, decision, failure, workflow, repo-rule, or model-performance records when the outcome is worth remembering.
Reflection.
Files changed, commands run, outcomes, decisions, and failure patterns become candidate memories.
Tools.
`query_memory` and `write_memory` are available to the agent under the selected permission policy.
Projection.
Readable `.picasso/memory/*.md` summaries mirror the structured store without becoming the source of truth.
What we never do.
No training.
Memory is retrieval, not model training.
No sponsor sharing.
Memory is never shared with sponsor systems.
No account leakage.
Memories are isolated per account and workspace.
No secret capture.
Environment values, private keys, credentials, and raw secrets are blocked from memory writes.
Same memory across surfaces.
Memory added through the CLI appears in the TUI and Mac app. Memory added through the Mac app is available to CLI and TUI runs through the shared local backend and optional sync path.
