How to use Encephalon: what you can do with it

What is Encephalon? Encephalon is a TypeScript package that stores durable, Git-tracked JSON knowledge records inside a repository and makes them searchable through a CLI and a synchronous JavaScript API.

How do I use it? Run npm install --save-dev encephalon at the Git repository root; then run npx --no-install encephalon init to create the baseline and the managed block in AGENTS.md and CLAUDE.md. Full steps below.

4 use cases

  • Record a team decision that future agents can find

    Store a decision as a Git-tracked record and find it again with compact search.

    View prompt
    In the repository <repo-path>, install Encephalon as a dev dependency, run init, then add one decision record about <decision topic> using a new ID. Expected output: JSON from compact search that includes the new record ID. Verify that the search for a term from the decision returns that ID.

  • Replace an outdated decision without losing history

    Supersede an old record with a new one so agents see the current choice and the past.

    View prompt
    In the repository <repo-path>, find the active decision for <subject>, then add a replacement record that supersedes it. Expected output: the add result and a compact search that includes superseded records. Verify that the old record ID is not returned by show with --active-only.

  • Give an agent project context in one batched call

    Fetch several searches and records together so an agent starts a task with context.

    View prompt
    In the repository <repo-path>, run gather with two search terms related to <task topic> and one known record ID. Expected output: results in the same order as the requested searches and shows. Verify that a missing show ID returns null and an empty search returns an empty array.

  • Resolve conflicting knowledge records after a merge

    Validate merged records and add one record that supersedes every conflicting head.

    View prompt
    In the repository <repo-path>, after a merge, run validate, then add one resolving record for subject <subject> that supersedes all conflicting heads. Expected output: validation errors before the fix and a clean validation after it. Verify that no old record file was deleted or edited.
