catchup

Catch the human up at their eye level, from state, not from memory.

Goal

catchup is the re-entry point for a lost human. Long agent cycles coin words, rename files, run experiments, and make calls faster than the owner can follow. Before any next action makes sense, the owner's mental model must be reloaded. catchup reads the live project state and returns a briefing a person with zero retained context can act on. It runs before the next move gets decided: catchup restores the map, so that decision starts from truth instead of a stale memory of it.

Workflow

1. Read live state only: recent file mtimes, git log/diffs, plan and state docs, re0-memo notes,

task boards. Never brief from conversation memory alone — memory is what drifted.

1. Anchor on the human's last touch (their last message, judgment, or commit). Everything after

that point is the delta; everything before it is assumed known and stays out.

1. Compose in decision order, not chronological order:

• Needs you — decisions, judgments, or inputs only the human can give, each self-contained

enough to act on without opening another file.

• Changed while you were away — outcomes, not process. "The plan's scoring rule was

replaced" beats "I ran three analysis passes."

• New words — every term coined or repurposed since their last touch, one line each, with

where it lives. Skip terms they already used themselves.

1. Gloss on first use: any project-specific term appearing in the briefing gets an inline

plain-language aside at its first occurrence, even if a glossary section follows.

1. Keep the default short (a screen or less). End with drill-down offers per section, not with

everything expanded.

Rules

• State-grounded: every claim traces to a file, commit, or artifact the human can open. No "as

we discussed."

• Read-only on the project. catchup briefs; it does not fix, rename, or decide.
• The ask comes first. A briefing that buries the one question needing the human is a log.
• Outcome voice, not journey voice. Narrating the agent's process is self-report, not briefing.
• Silence the settled: closed decisions and healthy metrics get one line or none.
• Honest completeness: "done" means verified done; "moved" is not "reconciled"; say which.
• Do not re-explain terms the human demonstrably knows (they used them first).

Verification

Before finishing:

1. Cold-read the briefing: no sentence requires pre-gap memory or an unglossed coined term to parse.
2. The "needs you" items are each actionable without opening another file.
3. Every claim has a checkable source (file, commit, artifact path).
4. It fits on a screen, with expansion offered rather than delivered.
