Agent Worklog

English | 繁體中文

Agent Worklog turns coding-agent sessions into weekly reports for managers, saving engineers time.

Capabilities

Agent Worklog currently works with OpenCode and can:

• Find OpenCode sessions across all projects, no matter which folder you are in.
• Select sessions from recent days, a calendar week, or a specific date range.
• Export sessions with opencode export --sanitize.
• Group Git worktrees that belong to the same repository.
• Keep child sessions linked to the correct repository.
• Leave out subagent sessions with --root-only when you only want root sessions.
• List each repository's session titles and working folders in the report.
• Summarize models, tokens, and tools from opencode stats.
• Include source activity IDs and confidence levels as supporting information.
• Check session information for common secret patterns before creating a report or sending data to an optional LLM.
• Continue when one session cannot be exported and add a warning to the report.
• On POSIX systems, write reports with owner-only 0600 permissions.

Requirements

• Python 3.11 or newer
• OpenCode available as opencode
• An OpenCode version that provides opencode db and opencode export --sanitize
• Git available as git

opencode stats is optional. Without it, Agent Worklog leaves out the usage section and still creates the report.

Installation

The recommended way to install the command-line tool is with pipx:

pipx install agent-worklog

You can also install it in a regular Python environment:

pip install agent-worklog

For development:

git clone https://github.com/mike840609/agent-worklog.git
cd agent-worklog
uv sync --locked --extra dev

Getting started

Check that OpenCode and Git are available:

agent-worklog doctor

Preview how Agent Worklog groups repositories for the previous full week:

agent-worklog scan --period last-week

Create the Markdown report without using an external LLM:

agent-worklog report --period last-week --no-llm

The default output is written under reports/.

Command reference

Command	What it does
doctor	Checks that opencode and git run and that the OpenCode database can be found.
scan	Shows which sessions fall in a period and how they group into repositories.
report	Writes the Markdown report for a period.

scan and report share these options:

Option	What it does
--days N	Reports the last N days, ending now.
--period last-week	Reports the previous full calendar week. last-week is the only accepted value.
--since ISO	Starts the period at an exact time.
--until ISO	Ends the period at an exact time. Requires --since.
--root-only	Leaves out subagent sessions.
--verbose	Also shows export, fallback, and LLM warnings.
--quiet	Shows only the session count for scan, or the output path for report.

report also accepts:

Option	What it does
--output PATH	Writes to this file instead of the default folder.
--force	Replaces the output file if it already exists.
--dry-run	Prints the Markdown instead of writing a file.
--no-llm	Creates the summary without an external LLM.

doctor accepts --quiet, which hides the list of checks and reports only through the exit code.

Three rules apply to scan and report:

• Give exactly one of --days, --period, or --since.
• Use --until only together with --since.
• Do not use --verbose and --quiet together.

Reporting periods

The last-week period means the previous full calendar week in the configured time zone. It starts on Monday at 00:00 and ends just before the next Monday at 00:00.

agent-worklog report --period last-week

Use --days to report activity from a number of recent days:

agent-worklog report --days 7

Use ISO timestamps to set exact start and end times:

agent-worklog report \
  --since 2026-07-20T00:00:00+08:00 \
  --until 2026-07-27T00:00:00+08:00

You must provide one of --period, --days, or --since. If you use --until, you must also use --since.

Subagent sessions

Subagent sessions are included by default. Each one is linked to the repository it actually ran in, so a subagent that worked in another checkout appears under that repository. To report only root sessions:

agent-worklog report --period last-week --root-only

Both scan and report accept --root-only.

Repository grouping

Agent Worklog checks each session separately to decide which repository it belongs to. It uses the following information in order:

1. The Git origin remote.
2. An ID created from a hash of the shared Git directory.
3. The OpenCode project ID.
4. An ID created from a hash of the working directory.
5. A separate unknown ID for the session.

SSH and HTTPS addresses for the same repository are treated as the same repository. Different branches are also grouped together. If a child session works in another repository, it stays linked to that repository.

LLM summaries

LLM summaries are optional. Agent Worklog connects to an OpenAI-compatible service only when all of the following are true:

• LLM support is turned on.
• --no-llm is not used.
• The API key is set in the selected environment variable.

For the default OpenAI-compatible configuration:

export OPENAI_API_KEY="..."
agent-worklog report --period last-week

LLM requests contain selected work information rather than full transcripts. Agent Worklog checks session information for common secret patterns before building each request. The request may still include repository and branch names, session and activity IDs, goals, commands, and filenames.

If the service times out, returns an HTTP 429 or 5xx error, or returns invalid data, Agent Worklog tries once more. If the second request fails, it creates a summary without the LLM. Use --no-llm to keep report generation on your computer.

Usage statistics

Each report includes a usage section built from opencode stats, covering models, tokens, and tools. OpenCode reports usage only for a period that ends now. The period shown in the report therefore starts when the report period starts and runs to the time the report is created. It covers the report period but is wider than it. If opencode stats is not available, Agent Worklog leaves the section out and adds a warning to the report.

Output and file handling

Set the output file with --output:

agent-worklog report \
  --period last-week \
  --no-llm \
  --output weekly.md

Agent Worklog does not replace an existing file unless you use --force:

agent-worklog report --period last-week --output weekly.md --force

Use --dry-run to preview the Markdown without writing a file:

agent-worklog report --period last-week --no-llm --dry-run

Use --verbose to show export and LLM fallback warnings. Use --quiet to show only the output path after a successful report.

Configuration

Agent Worklog uses environment variables for its settings. Variable names start with AGENT_WORKLOG_. Use __ between parts of a setting name. For example:

export AGENT_WORKLOG_REPORT__TIMEZONE="Asia/Taipei"
export AGENT_WORKLOG_REPORT__OUTPUT_DIRECTORY="reports"
export AGENT_WORKLOG_HARNESSES__OPENCODE__CLI__EXECUTABLE="opencode"
export AGENT_WORKLOG_LLM__MODEL="gpt-5-mini"
export AGENT_WORKLOG_LLM__BASE_URL="https://api.openai.com/v1/"
export AGENT_WORKLOG_LLM__ENABLED="false"

See the configuration guide for a complete list of settings.

Privacy

Agent Worklog requests OpenCode exports with --sanitize. It also checks selected session information for common secret patterns before creating a report or making an optional LLM request. Pattern checks cannot find every possible secret.

Reports may still contain private goals, filenames, commands, work descriptions, and the full paths of your working folders. Those paths often include your user name and the name of a client or employer, and the secret-pattern checks leave them in place on purpose so a report can say where the work happened. Always review a report before sharing it.

See Privacy and security for more details about data safety and current limits.

Failure handling and exit codes

If one session cannot be exported, Agent Worklog skips it and adds a warning to the report. If no sessions can be exported, the command stops with an error instead of creating an empty report.

Code	Meaning
0	Success
2	Invalid command options
3	Settings error
4	No matching activity
5	OpenCode or Git dependency error
7	Report file error

Current support and limits

• OpenCode is the only supported coding-agent tool.
• Agent Worklog gets session data through the OpenCode command-line tool. It does not read the SQLite database directly.
• Markdown is the only report format.
• Usage statistics cover a period that ends when the report is created. They do not match the report period exactly.
• Agent Worklog does not keep a cache between runs and does not provide an inspect command.
• Older sessions may use a backup ID if their working folders have been deleted.
• Repository grouping uses the Git information available when the report is created.
• Codex and Claude Code are not currently supported.
