A self-improving AI agent that stops repeating the mistake you corrected
Correct Octomind once and it saves the fix as a markdown lesson, backed by a verbatim quote of your message. The next session recalls it before the first answer.

How it works
Learning is on by default
The shipped config extracts and recalls lessons with no setup. Extraction and verification run on [supervisor.model], octohub:auto by default, so sign in with octomind login or point that model at your own provider.
~/.local/share/octomind/config/config.toml[supervisor.learning] enabled = true # shipped default [supervisor.learning.evolution] enabled = false # opt-in: compile lessons into skills and guardsCorrect it once, then type /done
Say what was wrong and what to do instead, in one message. /done hands a snapshot of the conversation to the extractor in the background; exiting the session and auto-compaction run the same pass.
octomind run # > Write a git commit message for this change: fixed a typo in README. Reply with the message only. # Fix typo in README # > No. In this repo commit messages always use Conventional Commits with a scope: # lowercase, imperative, no trailing period, like `docs(readme): fix typo`. Rewrite it. # docs(readme): fix typo /done /learning listThe next session applies it unprompted
Before your first message reaches the model, Octomind ranks the lessons stored for this project and role and sends the best ones in a pack of at most 2,000 tokens. /loglevel debug prints the exact pack.
octomind run /loglevel debug # > Write a git commit message for this change: added retry with backoff to the HTTP client. # Reply with the message only. # feat(http): add retry with backoff to client
What you get
A self-improving AI agent that learns only from what you say
The extractor first answers LEARN or NONE. It keeps a fix you gave or a rule you stated, and drops anything the agent worked out alone or a success nobody commented on. One pass asks for at most 3 lessons.
src/supervisor/learning/extract.rs:16Every lesson carries your exact words
Each candidate must quote you verbatim. Octomind checks the quote appears in one of your real messages, then a second model call confirms the quote supports the rule. If either check fails, the lesson is never written.
src/supervisor/learning/extract.rs:369Plain markdown you can read, edit and delete
Lessons are markdown files with YAML frontmatter under learning/<project>/<role>/ in the data dir (~/.local/share/octomind on macOS and Linux). Open them in any editor, or use /learning list, show, delete and clear in a session.
src/directories.rs:255Recalled before the turn, inside a 2,000-token budget
On the first message a short model call turns your request into search keywords; keyword and embedding rankings are fused with a 30-day recency half-life. The pack holds at most 2,000 tokens, 512 of them for user-wide rules, and is never written to the session log.
src/supervisor/learning/inject.rs:14Agent memory in two layers
Lessons are the built-in layer: short rules from your corrections, stored only as files. Long-term memory the agent writes on purpose (facts, decisions, notes) comes from octobrain, a separate MCP server that tap agents load through the memory-read and memory-write capabilities (remember, memorize, forget).
src/supervisor/learning/backend/mod.rs:5
One correction, one lesson, one recall
A throwaway repo called acme-api, a minimal role called coder, octohub:auto for every call. msg1.txt and msg2.txt hold the request and the correction from step 2, msg3.txt the new request from step 3, and cmd-show.txt is /learning show 1. The first answer was "Fix typo in README". After one correction, the exit distill stored a lesson (importance 0.9, backed by message 5) plus an orientation note. A brand-new session received both in a 291-token pack and wrote a Conventional Commit without being told. The background extraction after the correction cost $0.0008; the runs below cost under $0.02 in model calls, extraction included.

What it doesn't do
No published learning score
Octomind publishes no benchmark of how much the agent improves over time. The repo has retrieval contract tests, not an end-to-end learning score, so judge it on your own sessions: /learning list shows exactly what was stored and why. Docs →
Learns only from corrections and rules you state
A silent failure, a wrong answer you fixed by hand, or a success nobody commented on produces no lesson. Say what was wrong and what to do instead in one message, then type /done.
Lessons are scoped to one project and one role
They file under learning/<project>/<role>/, where project is the repository root name and role is the part before the colon. Another repo or role starts without them unless the extractor judged the rule user-wide and a second check agreed (learning/_/). A rule every repo needs belongs in its AGENTS.md. Docs →
Evolution into skills and guards is off by default
Compiling lessons into generated skills, guidance or guardrails is opt-in: set enabled = true under [supervisor.learning.evolution], or run with -c supervisor.learning.evolution.enabled=true. Candidates then pass a shadow screen and a randomized trial scored by the verify-gate (10 verdicts per arm by default) before they are promoted. Docs →
Long-term memory is a separate MCP server
Built-in learning is file-only. Searchable long-term memory comes from octobrain, its own binary and MCP server; tap agents install and wire it through their memory capabilities, while a bare role without them has lessons only.
Questions
What is a self-improving AI agent?
An agent that changes the scaffold around a fixed model, such as its instructions, memory or skills, based on experience. Octomind does it by turning your corrections into lessons it recalls in later sessions; the model weights never change.
Can an AI agent learn from its mistakes?
Octomind learns from the mistakes you point out. When you correct it and state the fix, it stores a lesson quoted from your message; a mistake nobody mentions is not learned.
Where are the lessons stored, and can I edit them?
As markdown files with YAML frontmatter in ~/.local/share/octomind/learning/<project>/<role>/ on macOS and Linux, and OCTOMIND_DATA_DIR moves that root. Edit them in any editor, or use /learning show and /learning delete inside a session.
What is agent memory, and how is it different from lessons?
Agent memory is anything an agent keeps between sessions. In Octomind, lessons are short rules distilled from your corrections and recalled automatically, while octobrain is a separate MCP server the agent writes to and searches on purpose for longer facts and notes.
Does learning cost extra?
A little: extraction, verification and the first recall of each session are calls to the supervisor model. In the run on this page, the background extraction after the correction cost $0.0008 on octohub:auto.
Can it learn the wrong thing?
It can only learn from text you wrote: every lesson must quote one of your messages verbatim and pass a second verification call. If a rule is wrong or outdated, /learning delete removes it, and a later correction can supersede it.
Other ways to run octomind
- Self-hosted agent An agent on your own box that takes work from webhooks, timers and your shell.
- Agentic workflows Multi-step agent pipelines in one TOML file: parallel, loop until it passes, fan-out.
- MCP client Plug any stdio or HTTP MCP server into a terminal agent, and add more mid-session.
- Agent orchestration A lead agent hands work to specialists at runtime. You get one bill and one verdict.
- Agent backend Your app talks to one WebSocket. octomind runs the agent, its tools and the bill per user.
