Worklog
A worklog is a persistent file — usually a Markdown log or a single SQLite table — that an AI coding agent writes to at the end of each session, recording current status, key decisions, blockers, and next steps so a later session can resume without re-deriving lost context.
The pattern crystallized in late March 2026: Monica Liu published agent-worklog on March 26, and Masters3D's essay framing the file as a coding 'lab notebook' followed two days later. At least five independent Claude Code skills reusing the same name shipped between May and July, from solo builders in the US and China alike.
Monica Liu's agent-worklog stores one Markdown file per task in a worklogs/ folder; saying 'start work' tells the agent to read it back, and 'end work' tells it to log next steps before the session ends.
Think of it as a shift-change logbook at a factory: whoever clocks in next reads it before touching anything, no matter who clocked out.

Why is it emerging now?
Since March 2026, independent builders have converged on the same word for the same fix: give a coding agent a small persistent file — Markdown or SQLite — that survives past the chat window. Monica Liu's agent-worklog and Masters3D's 'lab notebook' essay set the pattern; at least five Claude Code skills reusing the name shipped through July.

Independent repos reusing the same name signal real demand, but a major agent vendor could absorb it under AGENTS.md or HANDOFF.md branding.

Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
No comparison article exists yet for the competing session-persistence conventions; near-zero competition on this exact query.
Tutorial covering the trigger-phrase pattern ('start work' / 'end work') popularized by agent-worklog.
Roundup comparing the five-plus competing implementations: Markdown-per-task, single SQLite table, GitHub Issues backend.
Every current implementation is locked to one agent vendor's skill format; a cross-agent adapter is unclaimed.
Turns accumulated session entries into release notes or a standup summary — reuses data agents already write.
Visual proof of the cross-agent handoff use case; the pattern is inherently demoable on screen.
While startups raise millions for vector databases and knowledge graphs, the thing actually spreading between AI coding agents in 2026 is a plain Markdown file.
I tore out a vector database and a knowledge graph from my coding-agent setup and replaced both with a single append-only log.
Convergent evolution isn't just a biology term — it just happened to a markdown filename across three continents in 2026.
