[!] OPERATING LAYER / PLAIN-TEXT SOVEREIGN OS

build your
personal ai os

self.md maps the layer above the model: memory, tools, connectors, local runtimes, browser agents, coding workbenches, receipts, and boundaries.

Start with the operating problem. Pick the smallest stack that can act, remember, and prove what it did.

Developer essentials

Ship reliable software, from API contracts to production debugging.

  • Design an API contract

    Define a request and response contract that both client and server can verify.

  • Optimize database queries

    Locate expensive SQL and verify an index or query change with execution evidence.

  • Plan a safe migration

    Change a persisted schema without stranding existing readers or writers.

  • Trace a performance bottleneck

    Measure a slow user action and isolate where its time is spent.

  • Harden authorization

    Check that a caller can only read or change resources they own or may access.

  • Test a critical user journey

    Build a resilient end-to-end check around one business-critical action.

  • Design a background job

    Make asynchronous work restartable and safe to process more than once.

  • Review a dependency upgrade

    Upgrade a package with a clear compatibility and rollback check.

  • Debug with evidence

    Reproduce a failure, isolate its cause, and prove that the fix works.

  • Review the diff

    Find actionable defects in a change and explain their user impact.

  • Verify the result

    Check the original user flow and turn completion claims into evidence.

  • Map the codebase

    Find the routes, state, and boundaries that matter before touching unfamiliar code.

  • Handle API failures

    Make a network-dependent flow recover cleanly when the service does not.

  • Scope the work

    Turn an open-ended request into a small plan with a clear finish line.
