📝 WalkthroughWalkthroughRelay startup and coordination instructions no longer distribute workspace keys. Workers inherit the pinned workspace, register before relay operations, and report registration or inbox failures. Fan-out, team, and pipeline workflows now define observer access, worker tracking, handoffs, completion reporting, and lead-controlled release. Plugin metadata versions change to 0.2.0. ChangesRelay workspace protocol
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change removes workspace keys from prompts and replaces them with scoped observer tokens, but worker registration failures can still leave coordinators waiting for messages that will never arrive. This bounded workflow-correctness issue should be addressed or explicitly accepted before merging. Poem

…tokens The three pattern skills each mandated printing the raw workspace key in an observer URL — "Do not print a placeholder — print the real URL the user can click. This is mandatory." A workspace key is an administrative credential; a URL query string is the worst place to put one. They also required the key be copied into every worker prompt. That is unnecessary: `create_workspace` and `set_workspace_key` both pin the workspace to the project, and the relay MCP server a `relay-worker` subagent starts resolves that pin on its own. The mandate put an admin credential into N prompts and N transcripts to achieve nothing. - Step 3 now calls `get_observer_url`, which mints a scoped, expiring, read-only token. Requires the tool added in AgentWorkforce/relay#1422. - Worker prompts no longer carry the workspace key; the worker agent definition and SubagentStart hook now say the workspace is inherited and that a key must never be printed or requested. - The three skills' shared setup steps are now byte-identical, and all three carry the worker/stage tracking table and the "do not self-release" instruction that only relay-team had. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Jmke9G9s7ftrN49opNmdx1
Seven findings, all confirmed: - **Foreground pipeline deadlock (P1).** "Do NOT release yourself — stay idle" is right for backgrounded team/fanout workers but wrong for pipeline, whose stages run in the foreground: a worker that stays idle never returns, so the blocking Agent call never completes and the lead can neither read the DONE nor spawn the next stage. Pipeline workers now end their turn after DONE. The distinction between ending a turn and releasing a relay identity (`remove_agent`) is now stated explicitly in all three skills, since conflating them caused this. - **Concurrent runs share the project pin (P1).** The pin is last-writer-wins, so two leads in one checkout can cross workers into each other's workspace. Documented the one-team-per-checkout constraint and pointed at the ACK gate that already detects it — a worker in the wrong workspace finds no assignment and cannot ACK. - **Registration failure had no usable channel.** The old text said to report it "to your lead", but `send_dm` needs the registration that just failed. The worker now stops without retrying and makes the error its final response, which is what the lead gets back from the Agent call. Same for an empty inbox, the symptom of the pin race above. - **Plugin version was not bumped.** Marketplace clients use it to detect updates, so existing installs would have stayed on the prompts that leak workspace keys. Bumped to 0.2.0 in `plugin.json`, `package.json`, and the marketplace entry. - **`get_observer_url` may not be present yet** — it ships in AgentWorkforce/relay#1422. The instruction now falls back to `agent-relay observer` so a lead is never stuck on a missing tool. - **Later pipeline stages had no handoff requirement**, unlike stage 1; the final stage now also owes evidence. - **MD040**: gave the spawn examples a `text` language. Also drops the now-stale "if any of steps 1-2 fail, retry once" from the worker definition — step 2 became a standing prohibition, not a fallible action.

Handle out-of-band worker failures before waiting for relay messages.
Worker registration and no-assignment failures return through the Agent result. They do not produce relay ACK or DONE messages. Each coordinator must inspect that result before retrying or polling.

Summary
The three pattern skills (
relay-team,relay-fanout,relay-pipeline) each carried this instruction, verbatim, at step 3:That is a workspace admin key in a URL query string, mandated. It is also the exact thing AgentWorkforce/relay#1380 is trying to stop, and it directly contradicts the Codex and Gemini plugins in the relay repo, which say never to construct an observer URL from a workspace key.
They also each required the key be copied into every worker prompt ("You must include the workspace key in the prompt"). That turns out to be unnecessary:
create_workspaceandset_workspace_keyboth callpersistWorkspaceSession, which pins the workspace to the project (packages/cli/src/cli/lib/workspace-session.ts:37).relay-workersubagent getsmcpServers: ["agent-relay"], and that server'soptionsFromEnv()falls back toresolveWorkspaceSessionKey()— the project pin (packages/cli/src/cli/agent-relay-mcp.ts:1042).So the worker already resolves the workspace on its own. The mandate was putting an administrative credential into N prompts and N transcripts to achieve nothing.
Changes
get_observer_url, which mints a scoped, expiring, read-only token and returns a URL built from it. Depends on feat(cli): addagent-relay observerto mint read-only follow-along links relay#1422, which adds that tool — worth merging after it.relay-workeragent definition and theSubagentStarthook now say the workspace is inherited from the project pin, that a key must never be printed or requested, and what to do if registration fails (report to the lead, don't ask for the key).relay-teamhad. That omission was a real bug — a worker that self-releases after DONE breaks the review→fix loop.Some incidental tightening came with the rewrite (the "How spawning works" preamble was near-identical boilerplate in all three); the pattern-specific guidance — worker counts, foreground vs background, handoff artifacts — is unchanged.
Not addressed here
Real deduplication needs a decision I'd rather not make unilaterally. The three skills are
disable-model-invocation: trueslash-command entry points, and Claude Code has no include primitive for sharing text between sibling skills. The options are a build step that generates the three from one source, or collapsing them into one skill with a pattern argument (which changes/relay-fanoutinto/relay-team fanout). This repo has no rootpackage.jsonand no CI workflows, so an enforced drift check has nowhere to run today. For now the shared blocks are identical by hand.This is part of a series from a review of the Agent Relay skills and plugins across
