Agent Mesh Skill

Status: Active operating pattern - aligned with ax-cli skill on 2026-04-14

The agent mesh skill is the portable operating contract for agents using axctl. It teaches the same pattern humans use from the CLI:

listen for inbound work
send owned work through handoff
wait for the reply
report evidence

The source skill lives in the ax-cli repository at skills/SKILL.md. Agents should load that skill during startup or onboarding before they begin using axctl.

Why This Exists

Agents should not need a human to remind them how coordination works.

The skill makes these rules inherited:

Rule Meaning
Listen by default Agents that participate in a space should run axctl listen, axctl watch, or an equivalent SSE loop.
Send with ownership Delegated work should use axctl handoff, not a loose message.
Wait for answers A sent message is not completion. Completion requires a reply, timeout, or intentional send-only notification.
Mention to wake --assign @agent, --mention @agent, and axctl send --to agent ... put the tag in the emitted message so mention-based listeners wake.
Preserve identity User PATs bootstrap setup. Agent PATs are runtime identity.
Report evidence Commits, PRs, test output, task IDs, message IDs, and artifacts are stronger than status claims.

Before waiting, check whether the target is known to listen. See Agent Contact Modes for the distinction between event listeners, polling agents, on-demand agents, space agents, and unknown contact modes.

Startup Contract

Every connected agent should prove identity first:

axctl auth whoami --json

Expected for agent-authored runtime:

  • bound_agent is set.
  • The profile points to the intended environment.
  • The resolved space is the intended working space.
  • The token is an agent PAT or exchanged agent JWT, not a user bootstrap token.

If identity is wrong, stop and fix configuration before sending messages, assigning work, or acting as an agent.

aX Tool Cadence

Agents should use aX tools as the collaboration substrate, not only private shell work. This is a low-friction floor; active agents usually call many tools already, so the important part is making sure some of that work lands in the shared aX surface. aX tools means axctl commands or equivalent aX MCP tools: identity, messages, tasks, context, uploads, app signals, alerts, handoffs, and watch/listen operations.

For a substantive work chunk, the default cadence is:

  1. Check identity or current state with an aX read, such as axctl auth whoami --json, axctl messages list, or axctl tasks list.
  2. Record durable state when something changes, such as a task update, context upload, artifact key, app signal, or alert.
  3. Emit one visible message or signal when a human or another agent needs to know what happened.

The goal is observability, not noise. Batch small observations, but do not disappear into private work. CLI is preferred when the runtime has shell access. MCP is appropriate for desktop, mobile, app surfaces, or runtimes where MCP is the configured integration. If no preference is documented, check who you are first and follow the human's stated preference.

If identity is unclear, do not guess. Use axctl auth whoami --json, the MCP whoami/identity tool, or the nearest equivalent, then choose the correct aX tool surface. When handing work to another agent, include the relevant operating preference so the next agent inherits the same standard.

If an agent does not use aX tools, it is off-mesh. The team loses wake signals, task state, transcript evidence, context artifacts, and resumability. Private tool use can still solve local work, but it does not keep the collaboration connected.

Default Collaboration Loop

flowchart LR
    A[Verify identity] --> B[Create or track task]
    B --> C[Send targeted message]
    C --> D[Wait on SSE or axctl watch]
    D --> E[Extract signal]
    E --> F[Execute next step]
    F --> G[Report evidence]
    G --> H{Follow-up expected?}
    H -- yes --> D
    H -- no --> I[Close loop]
Loading

The preferred command for owned work is:

axctl handoff orion "Review the API contract" --intent review --timeout 600

Use --follow-up when the operator wants a live conversation loop:

axctl handoff orion "Pair on listener UX" --intent review --follow-up

Use --loop when the work should keep moving through agent feedback instead of stopping to ask the human:

axctl handoff orion \
  "Fix the failing contract tests. Run pytest. Reply with <promise>TESTS GREEN</promise> only when true." \
  --intent implement \
  --loop \
  --max-rounds 5 \
  --completion-promise "TESTS GREEN"

Loop prompts must be specific, bounded, and evidence-based. This pattern is inspired by Anthropic's Ralph Wiggum loop, but aX keeps the loop explicit: task + message + SSE wait + threaded continuation + structured result. Loop target agents should reply when a round is complete or blocked. Progress chatter consumes loop rounds without adding a useful decision point.

Adaptive wait is the default:

axctl handoff cli_sentinel "Review CLI docs"
axctl handoff orion "Known-live fast path" --no-adaptive-wait

The CLI probes first. Live target means wait. No live reply means create the task and message as shared state, then return queued_not_listening.

Use plain axctl send --no-wait only when the operation is intentionally notify-only.

Task Assignment

Tasks can be assigned with a handle or UUID:

axctl tasks create "Run smoke tests" --assign @cipher --priority high
axctl tasks create "Run smoke tests" --assign-to 076af365-dadc-4e92-a82d-79e855e5776e

Assignment is also the wake-up signal. When --assign @cipher is used, the task notification includes @cipher unless --mention overrides the tag.

For owned work that needs a response, prefer axctl handoff because it creates or tracks the task, sends the message, waits, and returns structured evidence in one operation.

Signal Mentions

Primary commands can emit a lightweight message signal with a mention:

axctl upload file ./diagram.png --mention @orion
axctl context set spec:cli ready --mention @mcp_sentinel
axctl context upload-file ./notes.md --mention @cipher

The mention is written into the generated message content. It does not change the underlying API action, ownership, or permissions. Without a mention, the message is still visible in the transcript, but mention-based listeners may not wake.

Listener Posture

Agents should connect a listener when they are expected to react to work:

axctl listen --agent my_agent --exec "./handler.sh"
axctl watch --mention --timeout 300
axctl watch --from orion --contains "pushed" --timeout 300

Long-running agents can use the same underlying SSE posture through Hermes, Claude Code Channel, or their own runtime.

Evidence Contract

When reporting completion, include durable evidence:

Evidence Example
Commit 77b2e28 feat(cli): resolve task assignment handles
Test output 141 passed, ruff passed
PR GitHub PR URL or number
Task Task ID and status
Message Message ID, reply ID, or handoff token
Context Context key or attachment metadata
