README

worklog

A per-project, SQLite-backed task and decision log for AI coding agents, exposed over MCP so work is remembered across sessions. One static binary, no runtime, no server to run, no cloud — the database is a single file in your project's .worklog/ directory.

It tracks not just what needs doing but what was done and why: every task carries its blocking dependencies, the GitHub issues/PRs it touches, the decisions made while executing it, and a running journal — so a fresh session can answer "where was I, and why did we do it this way?"

Why it exists

In-session task lists die when the session ends; prose notes aren't queryable. worklog fills the gap between them: structured, durable, cross-session work-state the agent reads on start and writes as it goes.

Install

go install github.com/MatLomax/worklog/cmd/worklog@latest   # needs Go 1.27+

Or download a prebuilt binary from the releases, or build from source (make build). Put worklog (or worklog.exe) on your PATH. It's a single static, dependency-free binary for Linux, Windows, and macOS — SQLite is compiled in (pure-Go modernc.org/sqlite, no cgo).

Per-project setup

cd your-project
worklog init          # creates ./.worklog/tasks.db (idempotent)

The database is resolved as --db / $WORKLOG_DB / $CLAUDE_PROJECT_DIR / current directory — walking up to the nearest ancestor .worklog/, else ./.worklog/tasks.db. It's local, gitignored working state — not committed.

The MCP server is attach-only: it opens an existing database but never creates one. So a globally-installed worklog stays inert in any project until worklog init (or /worklog:init) has been run there — it won't seed a database into every project you open.

Wiring it to an agent

Claude Code (plugin)

worklog ships as a Claude Code plugin — distributed through the MatLomax/claude-skills marketplace — that wires up the MCP server, the warm-load/session hooks, and a /worklog:init command in one install. The plugin is pure glue: it expects the worklog binary on your PATH (see Install).

/plugin marketplace add MatLomax/claude-skills
/plugin install worklog@claude-skills --scope project

Then, in each project you want tracked:

/worklog:init          # creates .worklog/tasks.db (idempotent)

Because the server is attach-only, the globally-installed plugin does nothing in a project until /worklog:init runs there. After it does, the SessionStart hook warm-loads open work, the Stop hook closes the session, and the worklog MCP tools are live.

Manual setup (without the plugin)

claude mcp add worklog -- worklog serve

Hooks in your settings:

{
  "hooks": {
    "SessionStart": [{ "hooks": [{ "type": "command", "command": "worklog context" }] }],
    "Stop":         [{ "hooks": [{ "type": "command", "command": "worklog session-end" }] }]
  }
}

Ready-made hook scripts (bash and PowerShell) are in hooks/.

Codex CLI

Codex is an MCP client too. Add to ~/.codex/config.toml:

[mcp_servers.worklog]
command = "worklog"
args = ["serve"]

All tools work identically. Session boundaries are handled automatically — the server closes its session when Codex disconnects, so no Stop hook is needed. Codex has no SessionStart-style context hook, so to warm-load either call task-next yourself at the start or add to your AGENTS.md:

At the start of a task, run worklog context (or call the task-next tool) to see open work.

Tools

Tool	Purpose
task-list	tasks in actionable order (unblocked first, then priority)
task-get	full detail: body, blockers, subtasks, links, decisions, journal
task-next	the single highest-priority actionable task
task-tree	the task forest / a subtree, nested
task-create	create a task, optionally under a parent, with blockers
task-update	change status/priority/parent/body; done unblocks dependents
task-toc / task-section-get / task-section-set	read/edit one ## section of a body
task-link	attach a GitHub issue/PR (full URL), commit, file, or URL
task-decide	record a decision + rationale made during execution
task-journal	append a freeform note to the running log
work-find	search tasks, decisions, and journal — find what was done
session-summary	close the session with a summary for the next one

CLI

worklog serve       [--db PATH]        run the MCP server over stdio
worklog init        [--dir DIR]        create .worklog/tasks.db
worklog context     [--db PATH] [-n N] print the "where was I" briefing
worklog session-end [--summary S]      close the current session
worklog version
