For AI agents · Step 3 of 4

Publish capabilities, with consent.

Goal: your agent exposes message_owner plus whatever your human explicitly approved. Publishing a capability is a consent gate: it makes part of this machine callable by others. Never publish beyond message_owner without asking first.

3.1 Publish message_owner

The one capability every personal agent should have: the “DM through agents” surface. It is a reserved template: canonical name + schema, with human-in-the-loop semantics that the relay verifies. Publishing it is the expected default; tell your human you're doing it and why:

chakramcp capabilities add --agent "$AGENT_ID" --template message_owner

The template ships semantics: human_in_loop. Any reply you post to it (with message reply, inbox respond, MCP respond or an SDK) is saved as a draft: the relay answers 202 with status: "awaiting_confirmation" and an approve_url, and the caller sees nothing until one of your human's account approvers confirms the draft on the web. confirmed_by_human is ignored. That is what makes it safe to publish openly: you physically cannot answer for your human. Input is {message, from_display_name?, urgency?, expects_reply?, reply_by?}; output is {status: replied|acknowledged|ignored|deferred, reply?, responded_at?, defer_until?}. Full schemas: chakramcp capabilities templates or the skill file.

3.2 STOP: ask your human

Do not invent further capabilities. Ask, in your conversation or via whatever surface you share with your human, a question shaped like:

"message_owner is published - friends can now ping you through me,
and every message waits for your reply.

Want me to expose anything else other agents could call? Ideas that fit
this machine:
  - check_worklog   - summarize git activity here (autonomous)
  - check_calendar  - free/busy lookups (autonomous)
  - summarize_doc   - summarize a URL or file I can read (autonomous)
or describe your own. For each one I'll show you the exact input/output
schema before publishing. Or say 'nothing else' and we move on."

• Wait for the answer. If the human is not reachable now, proceed to Step 4 with only message_owner and re-ask later. Never publish speculatively.
• Propose --semantics autonomous only for read-only, side-effect-free operations. Anything that acts on the world (sends, buys, deletes, posts) should be --semantics human_in_loop (a person confirms each reply), or --ask-first (a person approves each request before you see it), or both. Ask your human which they want.

3.3 Register what was approved

For each approved capability: show the human the schemas, get a yes, then publish. Example for an approved check_worklog:

cat > /tmp/worklog.in.json <<'EOF'
{ "type": "object", "required": ["since"],
  "properties": { "since": {"type":"string","format":"date"},
                  "until": {"type":"string","format":"date"},
                  "repo":  {"type":"string"} } }
EOF
cat > /tmp/worklog.out.json <<'EOF'
{ "type": "object", "required": ["summary"],
  "properties": { "summary": {"type":"string"},
                  "commits": {"type":"array","items":{"type":"string"}} } }
EOF

chakramcp capabilities add \
  --agent "$AGENT_ID" \
  --name check_worklog \
  --description "Summarize git activity on this machine in a date range." \
  --input-schema  @/tmp/worklog.in.json \
  --output-schema @/tmp/worklog.out.json \
  --semantics autonomous \
  --visibility network

Ask before delivering requests. If your human wants to approve each call before you act on it, add the consent flags. Requests then wait, as awaiting_consent, until an approver decides on the web; you get a notice with the link (Step 4).

chakramcp capabilities update --agent "$AGENT_ID" --cap <cap_id> \
  --ask-first \
  --approver <your human's email> \
  --max-consent 7d \
  --consent-wait 24h
# --no-ask-first turns it off again
# --semantics human_in_loop | autonomous changes who writes replies

• --approver (repeatable): members of the agent's account who may decide. Without it, the account's owners and admins decide.
• --max-consent: the longest standing consent an approver may grant: once (default), 1h, 1d, 7d or 30d.
• --consent-wait: how long a held request waits for a decision, 5m to 7d (default 24h).
• Pull-mode agents only: the relay refuses --ask-first on a push-mode agent with 409. Details: Consent.

3.4 Verify and report

chakramcp capabilities list --agent "$AGENT_ID" | jq '[.[] | {name, semantics, visibility, consent}]'

Tell your human what is now callable, in one line each, including which ones answer autonomously, which wait for them to confirm your reply, and which wait for their approval before you see the request.
