Retrospective edition / OBSERVE

Trace decisions without logging secrets

Connect run, turn, model, tool, handoff, approval, latency, usage, and terminal outcome with stable correlation identifiers.

01 / DECIDE

Architecture decision

Use it before scaling agent workflows or changing models, prompts, tools, and orchestration in production.

Connect run, turn, model, tool, handoff, approval, latency, usage, and terminal outcome with stable correlation identifiers. Map input, output, state, and side effects as one observable path before deciding which layer owns trace decisions without logging secrets.

02 / BUILD

Three-step implementation

  1. 01

    Frame the contract

    Write down the caller, data classification, success condition, timeout, cancellation, and ownership. Use it before scaling agent workflows or changing models, prompts, tools, and orchestration in production.

  2. 02

    Build one narrow path

    Implement one end-to-end path with request correlation, typed state, and reversible failure handling. Connect run, turn, model, tool, handoff, approval, latency, usage, and terminal outcome with stable correlation identifiers.

  3. 03

    Prove the outcome

    Turn acceptance into a repeatable fixture, contract test, or browser test. An incident can be reconstructed from identifiers and outcomes without needing unrestricted raw prompt access.

03 / BOUND

Production boundary

Redact credentials and sensitive content, define retention, and separate operational metrics from full conversation storage.

04 / PROVE

Acceptance evidence

An incident can be reconstructed from identifiers and outcomes without needing unrestricted raw prompt access.
