Summarize the current diff per file as markdown: a `## <filepath>` heading per changed file followed by a prose summary of its changes. Triggers: /changes, "summarize the diff", "what changed per file", "per-file summary of changes", "суммаризируй дифф", "что изменилось по файлам". Skip for reviewing quality or bugs (use /code-review) and for raw diff output (plain `git diff`).
Compress an expository note into readable prose backed by a certified Glossary via a standalone CLI — abstractive idea-compression, not extractive trimming. Re-expresses the note as flowing prose (carrying the thesis and the relations among terms) above an optional `## Workflow` checklist of the note's actionable directives and a definitions-only `## Glossary` table, collapsing restatements to one entry each and keeping only operational tokens verbatim; a different model fidelity-grades the glossary definitions and the workflow steps against the source and surfaces anything that did not translate. Replaces /cut. Use on /distill, "distill this", "compress this note", "make a glossary of this note", "tighten this into its ideas", "summarize as a glossary", "compress this guide/procedure into steps", "this note is too long/verbose", «дистиллируй», «сократи в глоссарий», «выжимка», «сделай глоссарий», «сократи гайд в шаги»; route whole-repo glossary maintenance to /glossary.
Route the current context to one expert persona and return that lens's candid second opinion. Auto-classifies to the best-fit persona, or name one explicitly. Runs the persona as a spawned subagent so its reasoning stays out of the main context. Roster spans engineering, product, go-to-market, and craft. Out of scope: generating new designs (use /design), arguing both sides (use /debate), stress-testing one plan (use /probe), scoring confidence in a claim (use /grade). Invoke explicitly with /opinion.
Personal knowledge management in an Obsidian vault. Use whenever the user wants to save, find, review, or organize knowledge, even without saying "vault". Triggers: saving links/articles as references, distilling concepts into cards, writing original notes, searching or quizzing saved content, listing active projects ("what am I working on"), explicit /vault commands, weekly-log operations (backlog/бэклог, planning, completing tasks, sleep). Excludes direct file edits not routed through /vault (editing a .md file in a code repo that is not a vault artifact), Obsidian app features (kanban, canvas, plugins, .base), web search. Skip for session save/resume ("wrapping up", "where did we leave off") — use /track.
Orchestrate a multi-step task by delegating to fresh subagents, keeping the orchestrator session small. Triggers: /work <task>, "orchestrate this", "delegate this work". Skip one-shot questions, single-file edits, and the ambient "let's work on X" / "start working on X" phrasing.
Test an existing thing's behavior against a falsifiable claim and capture the result as a standalone Markdown record in the current working directory. Self-contained — no vault, no external templates, no project linking. Triggers: /experiment, "run an experiment", "test this claim", "verify whether", "does X actually", "check if X works", "is X true", "falsifiable claim".

| argument-hint | [action] [args...] |
Full CLI coverage: 155 endpoints across todos, cards, messages, files, schedule, check-ins, timeline, recordings, templates, webhooks, subscriptions, lineup, chat, gauges, assignments, notifications, and accounts.
MUST follow these rules:
--jq when you need to filter/extract data; --json for full JSON; --md when presenting results to a human (see Output Modes below). Never pipe to external jq — use --jq instead.basecamp url parse "<url>" to extract IDs.basecamp/config.json before assuming project[@Name](mention:SGID) — zero API calls, embeds SGID directly (preferred for agents)[@Name](person:ID) — one API call, resolves person ID to SGID via pingable set@sgid:VALUE — inline SGID embed for pipeline composability@Name / @First.Last — fuzzy name resolution (may be ambiguous)
For todos, documents, and cards, content is sent as-is — use plain text or HTML directly.--in <project> or .basecamp/config.json. Cross-project exceptions: basecamp reports assigned for assigned work, basecamp assignments for structured assignment views, basecamp reports overdue for overdue todos, basecamp reports schedule for upcoming schedule across all projects, basecamp recordings <type> for browsing by type, basecamp notifications for notifications, basecamp gauges list for account-wide gauges.Choosing a mode:
| Goal | Flag | Format |
|---|---|---|
| Filter/extract JSON data | --jq '<expr>' | Built-in jq filter (no external jq needed). Implies --json; filter runs on the envelope. |
| Filter in agent mode | --agent --jq '<expr>' | Filter runs on data-only payload (no envelope), matching --agent contract. |
| Full JSON output | --json | JSON envelope: {ok, data, summary, breadcrumbs, meta} |
| Show results to a user | --md / -m | GFM tables, task lists, structured Markdown |
| Automation / scripting | --agent | Success: raw JSON data (no envelope); errors: {ok:false,...} object; no interactive prompts |
Always pass --json or --md explicitly — auto-detection depends on config and may not produce the format you expect. Use --md when composing reports, summarizing data, or displaying results inline. --agent is for headless integration scripts.
Other modes: --quiet (success: raw JSON, no envelope; errors: {ok:false,...}), --ids-only, --count, --stats (session statistics), --styled (force ANSI), -v / -vv (verbose/trace), --jq '<expr>' (built-in jq filter — see below).
Navigate unfamiliar commands with --agent --help — returns structured JSON describing any command:
basecamp todos --agent --help
{
"command": "todos",
"path": "basecamp todos",
"short": "...",
"long": "...",
"usage": "...",
"notes": ["..."],
"subcommands": [{ "name": "sweep", "short": "...", "path": "basecamp todos sweep" }],
"flags": [{ "name": "assignee", "type": "string", "default": "", "usage": "..." }],
"inherited_flags": [
{ "name": "json", "shorthand": "j", "type": "bool", "default": "false", "usage": "..." }
]
}
Walk the tree: start at basecamp --agent --help for top-level commands, then drill into any subcommand. Commands include notes with domain-specific agent hints (e.g., "Cards do NOT support --assignee filtering").
basecamp <cmd> --limit 50 # Cap results (default varies by resource)
basecamp <cmd> --all # Fetch all (may be slow for large datasets)
basecamp <cmd> --page 1 # First page only, no auto-pagination
--all and --limit are mutually exclusive. --page cannot combine with either.
--assignee me resolves to current user--due tomorrow / --due +3 / --due "next week" - natural date parsing.basecamp/config.json if --in not specifiedNote: Most queries require project scope (via
--in <project>or.basecamp/config.json). Cross-project exceptions:basecamp reports assigned,basecamp assignments,basecamp reports overdue,basecamp reports schedule,basecamp recordings <type>,basecamp notifications,basecamp gauges list.

Always parse URLs before acting on them:
basecamp url parse "https://3.basecamp.com/2914079/buckets/41746046/messages/9478142982#__recording_9488783598" --json
Returns: account_id, project_id, type, recording_id, comment_id (from fragment).
URL patterns:
/buckets/27/messages/123 - Message 123 in project 27/buckets/27/messages/123#__recording_456 - Comment 456 on message 123/buckets/27/card_tables/cards/789 - Card 789/buckets/27/card_tables/columns/456 - Column 456 (for creating cards)/buckets/27/todos/101 - Todo 101/buckets/27/uploads/202 - Upload/file 202/buckets/27/documents/303 - Document 303/buckets/27/schedule_entries/404 - Schedule entry 404Replying to comments:
# Comments are flat - reply to the parent recording_id, not the comment_id
basecamp url parse "https://...messages/123#__recording_456" --json
# Returns recording_id: 123 (parent), comment_id: 456 (fragment) - comment on 123, not 456
basecamp comment 123 "Reply" --in <project>

basecamp files download <upload_id> --out - --in <project>
Messages, todos, cards, and documents may contain images and file attachments
(mockups, screenshots, annotated designs). Show commands surface these as
field-scoped collections — content_attachments and/or description_attachments
— keyed by which rich-text attribute contained them. The notice field hints at
the download command.
Step 1: Fetch the recording and check for attachments
basecamp todos show <id> --json
# Response includes description_attachments when attachments are present
# Messages/documents use content_attachments; cards may have both
# The notice field hints: "3 attachment(s) — download: basecamp attachments download <id>"
Step 2 (one-shot): Download attachments with the show command
# --download-attachments fetches + downloads in one shot
basecamp todos show <id> --download-attachments --json
# content_attachments/description_attachments entries now include "path" pointing to local files
# Downloads to OS temp dir by default, or specify: --download-attachments /tmp/att
Step 2 (two-step alternative): Download separately
# Download all at once (shows progress on stderr)
basecamp attachments download <id> --out /tmp/attachments
Step 3: View images with your native file-read tool
For multimodal LLMs (Claude, Gemini), use your file-read tool on the path
from the response to view downloaded images directly — no browser needed.
This surfaces visual context (mockups, screenshots, annotated designs) that
is often the most important part of a Basecamp todo or message.
# Stream a single image to stdout for piping
basecamp attachments download <id> --file mockup.png --out -
# Select by index when names collide
basecamp attachments download <id> --index 2 --out -
Key pattern: When a show command response contains content_attachments
or description_attachments, always download and view them — visual context is
often more important than the text content. Use --download-attachments for
one-shot fetch+download, or follow the breadcrumb hint for two-step control.

basecamp todos sweep --overdue --complete --comment "Done" --in <project>
Flags: --assignee (todos only - not available on cards/messages), --status (completed/incomplete), --overdue, --list, --due, --limit, --all
Todolists are containers for todos. Create a todolist before adding todos.
basecamp todolists list --in <project> --json # List todolists
basecamp todolists show <id> --in <project> # Show details
basecamp todolists create "Name" --in <project> --json # Create
basecamp todolists create "Name" --description "Desc" --in <project>
basecamp todolists update <id> --name "New" --in <project> # Update
Note: Cards do NOT support --assignee filtering like todos. Fetch all cards and filter client-side if needed. If a project has multiple card tables, you must specify --card-table <id>. When you get an "Ambiguous card table" error, the hint shows available table IDs and names.
basecamp cards list --in <project> --json # All cards
basecamp cards list --card-table <id> --in <project> # Specific table (required if multiple)
basecamp cards list --column <id> --in <project> # Cards in column
basecamp cards columns --in <project> --json # List columns (needs --card-table if multiple)
basecamp cards show <id> --in <project> # Card details
basecamp card "Title" "<p>Body</p>" --in <project> --column <id>
basecamp cards update <id> --title "New" --due tomorrow --assignee me
basecamp cards move <id> --to <column_id> # Move to column (numeric ID)
basecamp cards move <id> --to "Done" --card-table <table_id> # Move by name (needs table)
basecamp cards move <id> --to "Done" --position 1 --card-table <table_id> # Move to position
basecamp cards move <id> --on-hold # Move to on-hold of current column
basecamp cards move <id> --to <column_id> --on-hold # Move to on-hold of target column
Archived/trashed cards: cards list only returns active cards. For archived or trashed cards, use basecamp recordings cards --status archived --in <project> or --status trashed.
Identifying completed cards: Cards in Done columns have parent.type: "Kanban::DoneColumn" and completed: true. Use this to identify completed cards that haven't been archived.
Limitation: Basecamp does not track when cards are moved between columns. The updated_at field updates on any modification and cannot reliably indicate when a card was completed.
Card Steps (checklists):
basecamp cards steps <card_id> --in <project> # List steps
basecamp cards step create "Step" --card <id> --in <project>

basecamp timeline me --json # Your activity
basecamp timeline --person <id> --json # Person's activity
basecamp timeline --watch # Live monitoring (TUI)
basecamp timeline --watch --interval 60 # Poll every 60 seconds
Use --limit N to cap results or --all to fetch everything (default: 100 events). --all and --page cannot be combined with --watch.
Use basecamp recordings <type> for cross-project type browsing. For assigned todos, prefer basecamp reports assigned — recordings do not include assignee data and cannot be filtered by person.
basecamp recordings todos --json # All todos across projects
basecamp recordings todos --all --json # All todos (paginate through all)
basecamp recordings messages --in <project> # Messages in project
basecamp recordings documents --status archived # Archived docs
basecamp recordings cards --sort created_at --direction asc
basecamp recordings cards --status archived --all --json # Include archived cards
Types: todos, messages, documents, comments, cards, uploads
Status filtering: By default, only active recordings are returned. Use --status archived or --status trashed to query other statuses. You may need separate queries to get complete data (e.g., active + archived).
Status management:
basecamp recordings trash <id> --in <project> # Move to trash
basecamp recordings archive <id> --in <project> # Archive
basecamp recordings restore <id> --in <project> # Restore to active

The CLI uses two directory namespaces: basecamp for your Basecamp identity and project relationships, basecamp for tool-specific operational data.
~/.config/basecamp/ # Basecamp identity (DO NOT read credentials)
├── credentials.json # OAuth tokens — NEVER read or log
├── client.json # DCR client registration
└── config.json # Global preferences (account_id, base_url, format)
~/.cache/basecamp/ # Tool cache (ephemeral, auto-managed)
├── completion.json # Tab completion cache
└── resilience/ # Circuit breaker state
.basecamp/ # Per-repo config (committed to git)
└── config.json # Project defaults (project_id, account_id, todolist_id)
Per-repo config: .basecamp/config.json
{
"project_id": "12345",
"todolist_id": "67890"
}
Initialize:
basecamp config init
basecamp config set project_id <id>
basecamp config set todolist_id <id>
Config Trust:
Authority keys (base_url, default_profile, profiles) in local/repo configs are blocked until explicitly trusted. This prevents a cloned repo's config from redirecting OAuth tokens.
basecamp config trust # Trust nearest .basecamp/config.json
basecamp config trust /path/to/.basecamp/config.json # Trust specific config file
basecamp config trust --list # Show all trusted configs
basecamp config untrust # Revoke trust for nearest config
basecamp config untrust /path/to/.basecamp/config.json # Revoke trust for specific path
Check context:
cat .basecamp/config.json 2>/dev/null || echo "No project configured"
Global config: ~/.config/basecamp/config.json (account_id, base_url, format preferences)
General diagnostics:
basecamp doctor --json # Check CLI health, auth, connectivity
Rate limiting (429): The CLI handles backoff automatically. If you see 429 errors, reduce request frequency.
Authentication errors:
basecamp auth status # Check auth
basecamp auth login # Re-authenticate
basecamp auth login --scope full # Full access (BC3 OAuth only)
basecamp auth login --device-code # Headless: display URL, paste callback
Network errors / localhost URLs:
# Check for dev config
cat ~/.config/basecamp/config.json
# Should only contain: {"account_id": "<id>"}
# Remove base_url/api_url if pointing to localhost
Not found errors:
basecamp auth status # Verify auth working
cat ~/.config/basecamp/accounts.json # Check available accounts
Required arguments are positional (not flags):
basecamp todo "Buy milk" (not --content)basecamp card "New feature" (not --title)basecamp message "Subject" "Body" (not --subject)basecamp chat post "Hello" (not --content)basecamp comment <id> "Text" (not a flag)basecamp webhooks create "https://..." --in <project> (not --url)basecamp checkins answer create <question-id> "content" (not --question)--date YYYY-MM-DD is optional for checkins answer create; if omitted, it defaults to todayMissing argument errors (code: "usage"): When a required positional argument is missing, the CLI returns a structured error naming the specific argument. Use this for elicitation:
$ basecamp todo --json
{"ok": false, "error": "<content> required", "code": "usage",
"hint": "Usage: basecamp todo <content>"}
$ basecamp comments create 123 --json
{"ok": false, "error": "<content> required", "code": "usage", ...}
The error field names the missing <arg> — use it to prompt the user for the specific value.
URL malformed (curl exit 3): Special characters in content. Use plain text or properly escaped HTML.
The CLI has a built-in --jq flag powered by gojq — no external jq binary required. Always prefer --jq over piping to external jq.
# Extract fields from data array
basecamp todos list --in <project> --jq '.data[] | select(.completed == false) | .title'
basecamp todos list --in <project> --jq '.data | length'
basecamp todos list --in <project> --jq '[.data[] | {id, title, status}]'
# Access envelope metadata
basecamp todos list --in <project> --jq '.breadcrumbs[0].cmd'
basecamp todos list --in <project> --jq '.meta.stats.requests'
# Filter and transform
basecamp cards list --in <project> --jq '[.data[] | select(.completed == true) | .title]'
basecamp people list --jq '[.data[] | {name: .name, email: .email_address}]'
--jq implies --json — no need to pass both. String results print as plain text; objects and arrays print as formatted JSON.
