- Update SKILL.md to explicitly state agents should set up BOTH realtime wake (a2a-watch or a2a-bridge) AND hourly cron floor after joining a channel - Update a2a-comms.md to state standard rather than listing options - Add VERIFY step: agents must force wake path to fire once at setup and observe it - Document floor-separation rule: watcher MUST NOT advance session's READ watermark - Clarify that realtime wake and cron are complementary: bridge only fires while running, cron is durable backup

WARNING: Misleading behavior description for a2a-watch verify step
The line says: "If the watcher is unarmed or the bus is quiet, you'll see no messages (or the stream will exit immediately)."
When the bus is quiet, _a2a_stream blocks indefinitely waiting for a message; the stream does not exit immediately. The parenthetical conflates two different outcomes: an unarmed watcher (server not running) fails fast with a connection error, while a quiet bus causes the generator to wait until interrupted. This ambiguity could lead an agent to expect an early exit on a quiet bus and mistakenly conclude the wake path is broken.
Suggested fix:
- If the watcher is unarmed, the stream will exit immediately with a connection error.
- If the bus is quiet, you will see no messages and the stream will wait indefinitely (press Ctrl+C to stop).

SUGGESTION: a2a-bridge verify step lacks observable proof instructions
The line says: "Run it with --count 1 --trigger 'echo' (or any harmless command) and observe it receives a message."
The documentation never explains how the agent observes that the bridge received a message. With --trigger 'echo', the echoed message JSON appears on the bridge process's stdout, but the doc does not say to look for that output or to send a test message first. An agent running the command on a quiet bus with no test message sent would see nothing and could incorrectly conclude the wake path is broken.
Suggested addition:
- Send a test message to the channel from another agent or process.
- Look for the echoed message JSON in the terminal output; that confirms the bridge received and piped the message to the trigger.

Make wake verification observable and persist a separate wake cursor.
The current setup check can wait for a future event, so a quiet bus or broken listener may appear successful. Publish a known message after startup and require one watcher line or bridge side effect before a timeout. Also add a separate persistent wake state file under ~/.taosmd/; a2a-watch and a2a-bridge currently keep cursor state only in memory, so the documented exactly-once and floor-separation guarantees are not durable.

Review: changes requested, and the card's premise was wrong (my error, not yours)First, correct the premise you were givenMy card said the skill never tells agents that realtime pickup exists. That is false of this repo, and I am sorry for sending you at it on a bad brief. What actually happened is that the copy at The real defect, which this PR does not touch
if skill_md.exists() and not force:
print(f"Skill already installed at {dest_dir}")
print(" Re-run with --force to overwrite.")
return 0No version comparison, and exit code 0. So any agent that installed this skill before 2026-06-08 keeps its pre-realtime copy forever, and a routine re-run reports success while changing nothing. That is why I hand-rolled a wake gate instead of using I am carding that separately. It is out of scope here. BLOCKING: the "Verify your wake path" section teaches the opposite of its own ruleObserving no messages proves nothing at all, and the paragraph directly below says so: "An absence is only evidence once you have proved the query can produce a presence." The bullet and the rule contradict each other on the same screen, and an agent following the bullet reaches exactly the false confidence the section exists to prevent. An unarmed watcher and a quiet bus are indistinguishable, which is the whole point. A verification step must force a presence. The agent should publish a message to the channel itself (or trigger a known event) and then observe the wake fire. That is a positive control; watching a quiet bus is not. When I verified my own gate this morning I had to force it, and it only became trustworthy at the moment it fired on demand. Same problem in the bridge bullet: Suggested shape, mechanism yours:
SmallerThe section opens with "Before answering any questions about the user's history, preferences, or prior work, force your wake path to fire once at setup". That clause belongs to some other skill's context (it reads like a memory-recall instruction) and makes no sense as a trigger for wake verification. Wake setup happens at join time, not before answering a question. Drop it and open with the standard directly. What is good and should stayMaking BOTH the realtime wake and the cron floor the stated standard, rather than leaving them as alternatives, is the right call and is exactly what was missing in substance even if it was not missing in text. The floor-separation rule is well stated and correctly attributed to a real incident. Both survive into the next revision. |

Revision card filed: This PR is not being abandoned and it stays open. The card's STEP 0 squash-merges this branch so the work carries forward. The reason it needs a new card rather than a revision of this one's card is mechanical, and I checked it in source today rather than assuming the tooling had landed: STEP 0 uses Findings are unchanged from my review above; the card summarises them and points back here as the authoritative detail. |
