All-seeing agent tracker

Kanpan

All-seeing agent tracker. The name combines Sino-Japanese 看 (kan, "to look", as in 看板 kanban) and Greek πᾶν (pan, "all") -- a unified view that aggregates state from all sources (mngr agent lifecycle, git branches, GitHub PRs and CI) into a single board.

Launch with mngr kanpan. Requires the gh CLI to be installed and authenticated.

Filtering

Filter which agents appear on the board using CEL expressions:

# Show only agents for a specific project
mngr kanpan --project mngr

# Show only running agents
mngr kanpan --include 'state == "RUNNING"'

# Exclude done agents
mngr kanpan --exclude 'state == "DONE"'

--include and --exclude accept arbitrary CEL expressions (repeatable). --project is a convenience shorthand that translates to an include filter on labels.project. Multiple --project flags are OR'd together.

When any filter is active, the header displays a [filtered] indicator.

Data sources

Kanpan uses pluggable data sources to fetch per-agent data. Each data source produces typed fields that become columns on the board. Built-in data sources:

• repo_paths: Extracts GitHub repo path from agent remote labels (infrastructure data for other sources)
• git_info: Computes commits-ahead count from git rev-list
• github: Fetches PRs, CI status, merge conflict status, and unresolved review comments via the gh CLI

Configuration

Data sources are configured in your mngr settings file:

[plugins.kanpan]
column_order = ["name", "state", "commits_ahead", "conflicts", "unresolved", "ci", "pr"]

# GitHub data source: all fields enabled by default
[plugins.kanpan.data_sources.github]
enabled = true
# Toggle individual fields:
# pr = true
# ci = true
# conflicts = true
# unresolved = true

Shell command data sources

Add custom columns backed by shell commands:

[plugins.kanpan.shell_commands.slack_thread]
name = "Find Slack thread"
header = "SLACK"
command = """
THREAD=$(find-slack-thread --channel project-mngr --search "$MNGR_AGENT_NAME")
if [ -n "$THREAD" ]; then
  echo "$THREAD"
fi
"""

Shell commands run once per agent in parallel. The stdout (trimmed) becomes the column value. Commands receive environment variables:

Variable	Description
MNGR_AGENT_NAME	Agent name
MNGR_AGENT_BRANCH	Git branch (empty if none)
MNGR_AGENT_STATE	Agent lifecycle state
MNGR_AGENT_PROVIDER	Provider instance name
MNGR_FIELD_PR_NUMBER	PR number (from cached fields)
MNGR_FIELD_PR_URL	PR URL (from cached fields)
MNGR_FIELD_PR_STATE	PR state: OPEN, MERGED, or CLOSED (from cached fields)
MNGR_FIELD_CI_STATUS	CI status (from cached fields)
MNGR_FIELD_<KEY>	Display text for any other cached field, uppercased key (e.g. MNGR_FIELD_COMMITS_AHEAD)

Label-backed columns

Add extra columns that read from agent labels:

# Column showing the agent's "blocked" label value
[plugins.kanpan.columns.blocked]
header = "BLOCKED"
# label_key defaults to the field key ("blocked") if omitted
label_key = "blocked"

[plugins.kanpan.columns.blocked.colors]
yes = "light red"
no = "light green"

Each entry defines a column keyed by the field key (e.g. blocked). The label_key specifies which agent label to read (defaults to the field key). Use colors to map label values to urwid color names.

Disabling a data source

Set enabled = false to disable a data source. Its cached fields are excluded from the board:

[plugins.kanpan.data_sources.github]
enabled = false

Custom commands

Add to your mngr settings file (e.g. .mngr/settings.toml):

[plugins.kanpan.commands.c]
name = "connect"
command = "mngr connect $MNGR_AGENT_NAME"

[plugins.kanpan.commands.l]
name = "event"
command = "mngr event $MNGR_AGENT_NAME"
refresh_afterwards = true

Each entry defines a keybinding (the table key, e.g. c) that appears in the status bar and runs with the MNGR_AGENT_NAME environment variable set to the focused agent's name. Custom commands override builtins when they share the same key. Set enabled = false to disable a builtin.

By default, custom commands run immediately on the focused agent. Set markable = true to make a command use dired-style batch marking instead: pressing the key marks agents, then x executes all marks at once.

[plugins.kanpan.commands.s]
name = "stop"
command = "mngr stop $MNGR_AGENT_NAME"
markable = true
refresh_afterwards = true

Column order

Control which columns appear and in what order:

[plugins.kanpan]
column_order = ["name", "state", "commits_ahead", "ci", "pr"]

Built-in column names: name, state. Data source field keys: commits_ahead, pr, ci, conflicts, unresolved, repo_path. Shell command field keys match their config key (e.g. slack_thread).

Section order

By default, sections are displayed in this order: Done (PR merged), Cancelled (PR closed), In review (PR pending), In progress (draft PR), In progress (no PR yet), In progress (PRs failed), Muted. To customize:

[plugins.kanpan]
section_order = ["STILL_COOKING", "PR_DRAFT", "PR_BEING_REVIEWED", "PR_MERGED", "PR_CLOSED", "MUTED"]

Valid section names are: PR_MERGED, PR_CLOSED, PR_BEING_REVIEWED, PR_DRAFT, STILL_COOKING, PRS_FAILED, MUTED. Sections not listed in section_order are omitted.

The PR column displays clickable hyperlinks (OSC 8) in terminals that support them. When an agent has a PR, the column shows #<number> linked to the PR URL. When no PR exists but the branch is pushable, it shows +PR linked to the create-PR URL.

Refresh behavior

Kanpan uses two refresh strategies:

• Full refresh (manual 'r' key, periodic 10-minute timer): runs all data sources. Only one can be in flight at a time -- pressing 'r' while a refresh is running is ignored.
• Agent-only refresh (after push, delete, custom commands): runs only local data sources (repo_paths, git_info). Remote data (PR, CI) is carried forward from the previous snapshot.

Both are configurable:

[plugins.kanpan]
# Seconds between periodic full refreshes (default 10 minutes)
refresh_interval_seconds = 600.0
# Seconds before retrying after a failed full refresh
retry_cooldown_seconds = 60.0
