Tools (38)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

board_assign
Assign a task to an agent and notify them — records the assignee AND leaves a 'please look at task #N' message in that agent's inbox. Passive: the board records the ask; the agent reads its inbox and decides to act. Never launches the agent.
board_attribute
Record a single attribution (commit + optional file) to a human or AI actor.
board_blame
Blame → narrative: trace a file line back to the session that introduced it and surface that session's other work, decisions, and handoffs.
board_check
Governance gate: assert policy over commits and report pass/fail plus violations. Read-only — reports, does not block. Use in CI to keep unreviewed AI work off a branch.
board_claim
Claim a task by key so other agents know you own it. If another agent already holds it, the response reports the conflict (the board records but does not block).
board_decision
Record a decision and its rationale so other agents see what was decided and why.
board_evidence
Attach evidence (file path, URL, log, test run) supporting some work.
board_explain
Explain a commit: its AI attribution, reviews, and related decisions.
board_export
Export a portable attribution bundle (attributions, reviews, sessions, decisions) for a commit range, so attribution survives push/PR into a team board or CI.
board_file_changed
Record that you touched a file. If a task key is given, the response reports files other agents already changed for that task (conflict awareness).
board_handoff
Hand off work to another agent with a summary of the state at handoff.
board_handoffs
Handoffs left FOR you — the work another agent passed to you, with context and open questions.
board_heartbeat
Stamp the active session as alive (real-time liveness, so other agents can tell active from stale).
board_import
Import an attribution bundle (as produced by board_export) into this board. Idempotent.
board_inbox
Read what's waiting for you: messages (addressed or broadcast) and handoffs left for you.

Show 23 more tools

board_ingest
Description is built at runtime.
board_link
Attribute a Git commit's files to the current session (who actually produced the code). Reads Git; never rewrites history. Optionally writes an additive git note.
board_message
Leave a message for another agent (or broadcast with to='all').
board_note
Broadcast a free-form status note to the board.
board_progress
Report task progress 0–100 (moves it to in-progress, or done at 100). Use this from an agent as it works a task so the kanban shows a live progress bar.
board_prune
Retention: delete messages/evidence/file-change rows created before an ISO time. The audit timeline is never pruned.
board_redact
Hide a timeline entry's content at the read layer (the hash chain stays valid — this is not cryptographic erasure).
board_report
Accountability scorecard: review coverage, AI/human ratio, per-agent breakdown, session and risk counts.
board_review
Record who reviewed a commit and the outcome (human or AI reviewer).
board_risk
Flag an open risk the next agent should know before acting.
board_sign
Sign the current timeline head with the active session's key (attests board state through the head seq).
board_since
Subscribe primitive: poll for timeline events after a given seq. Returns the new head seq and events (optionally filtered to those relevant to an agent). Call board_status first to get a starting seq.
board_status
Read the board: active agents, open tasks and who holds them, unread messages, open risks, recent history. Call this before starting work to see what other agents are doing.
board_task
Get a task's full kanban card (status, progress, assignees, active-agent count, impacted files, linked risks) by key or number (#145).
board_task_define
Create or update a task's kanban fields: title, description (what it is), project, impact (change surface), and risk level. New keys get a stable task number.
board_tasks
List all tasks as kanban cards (for a board/kanban view).
board_timeline
Read the append-only, hash-chained history of everything that happened on the board.
board_trailers
Git trailer lines encoding a commit's attribution, for embedding in a commit message.
board_trust
Show signature trust: which sessions have signed the timeline and whether each signature is valid and still current.
board_unreviewed
List AI-produced commits that have never been reviewed by a human.
board_who
Who changed a file: Git authors, AI sessions that touched it, and commit attributions. Pass a line number to trace which session introduced that line.
session_start
Start an execution session. Subsequent writes and links attribute to it. Captures machine, working directory, git branch, and repository.
session_stop
Close the active session (or a specific one).
