Add antianqi/openclaw-acp-bridge v0.1.3 - peer collaboration Bridge for MiniMax Code

[antianqi]

Summary

Adds plugins/antianqi/openclaw-acp-bridge — a Bridge that lets MiniMax Code sessions collaborate peer-to-peer with the OpenClaw-mcode-ACP inbox protocol instead of one-shot master/slave task calls.

MiniMax Code can now:

• Read incoming messages from the ACP inbox (inbox_read)
• Push progress and partial answers (inbox_write)
• Ask blocking questions and wait for the peer's answer (inbox_ask / inbox_answer)
• Greet a new peer session (peer_greet)

Two Skills ship in the Plugin:

• acp-collab — peer-to-peer inbox collaboration
• acp-task-dispatch — dispatch self-contained tasks to the ACP HTTP server

What's inside

• plugin.json — $schema=agent-plugins.org/schemas/1.0.0/plugin.schema.json, name=openclaw-acp-bridge, version=0.1.3, license=Apache-2.0
• README.md — overview, Supported platforms table, Authentication, SDK compatibility contract, smoke test, Data and network, Test evidence
• LICENSE — Apache-2.0 (full text)
• scripts/smoke.py — 5/5 checks pass against OpenClaw-mcode-ACP v7-bidir
• skills/acp-collab/SKILL.md — peer inbox protocol (frontmatter present, YAML valid)
• skills/acp-task-dispatch/SKILL.md — task dispatch Skill (frontmatter present, YAML valid)

Validation

Ran npm run validate from this fork's main. The new hosted Plugin passes:

OK   plugin antianqi/openclaw-acp-bridge

(Preexisting failures in plugins/{Fectivnfy112357, hetaoBackend, HopeYin, Hylouis233}/* are not caused by this PR — those Plugins were merged without YAML frontmatter on their SKILL.md. Flagging them here so the maintainer can triage.)

SDK / runtime contract

This Plugin assumes acp_tools.py server v7-bidir+ with these functions:
create_task, get_task, list_history, inbox_read, inbox_write, inbox_ask, inbox_answer, peer_greet.

The token is read at call time from $ACP_TOKEN or <ACP_HOME>/.acp_token. It is sent only to http://localhost:9999/acp/* (HTTP loopback). Never logged, never echoed.

Test evidence

$ python scripts/smoke.py
[1/5] ACP_HOME resolves ... OK
[2/5] SDK imports ... OK
[3/5] server /acp/health ... OK
[4/5] inbox write/read roundtrip ... OK
[5/5] no hardcoded absolute paths ... OK

(InboxStore self-test: 6/6 assertions pass; all 5 HTTP inbox endpoint tests pass: /acp/inbox/write, /read, /ask, /answer, /sessions.)

Compatibility

Platform	Status
Windows 10/11	Supported (primary)
macOS 13+	Supported
Linux (x86_64)	Supported

No hardcoded absolute paths anywhere. The Plugin uses forward slashes internally (posixpath) and only resolves paths through $ACP_HOME.

Replaces v0.1.3 in hetaoBackend/MiniMax-Code-Plugins

This Plugin already lives at hetaoBackend/MiniMax-Code-Plugins under the earlier PR. With the move of the community registry to this organization, this PR re-hosts the same v0.1.3 content under the new namespace. The earlier PR can be closed once this one merges.

Review result: do not approve / do not merge yet.

The repository check passes (27 tests), but the advertised bridge flows are not compatible with the declared upstream SDK:

• skills/acp-task-dispatch/SKILL.md:36-66 imports list_history although upstream exposes history, treats create_task() as a mapping although it returns a task-id string, expects {"tasks": [...]} although history returns a list, and polls for completed although the terminal success state is succeeded.
• skills/acp-collab/SKILL.md:84-90 treats inbox_read() as a mapping although it returns a list; the documented peer_greet() path also attributes messages to the wrong sender.
• The README says ACP_TOKEN or <ACP_HOME>/.acp_token configures authentication (README.md:59-72), but the actual upstream client used by the Skills does not read those values; the smoke test bypasses the SDK and manually sends the token.
• scripts/smoke.py:103-149 accepts an unrestricted ACP_BASE_URL and sends ACP_TOKEN there, so a non-loopback URL can capture the token, contradicting README.md:61-66.
• README.md:128-130 claims a pinned CI workflow, but .github/workflows/openclaw-acp-bridge-smoke.yml is absent from the PR/tree.

Please pin and test one upstream revision, make the Skills match its actual API/auth contract, restrict the smoke-test destination or remove token use from it, and add the claimed CI workflow before requesting another review.

Thanks for the review. Pushed four commits on top of 0641f5c, one per blocking issue. Quick recap:

Code / doc fixes

• scripts/smoke.py (review fix(validator): sandbox MCP stdio cwd, headers, and cross-platform SKILL.md #4) — urlparse + host allowlist
  ({127.0.0.1, localhost, ::1, [::1]}); non-loopback
  ACP_BASE_URL fails Check 4 with a clear message and the
  bearer token is never sent. Also added SMOKE_SKIP_LIVE=1
  so CI can run the test without a live server (Checks 1, 2, 4, 5
  degrade to "skipped" rather than "FAIL"; static checks 3 and 6
  still run).
• .github/workflows/openclaw-acp-bridge-smoke.yml (review Add antianqi/tool-map v0.2.0: persistent cross-platform tool inventory #5)
  — runs the smoke test under ubuntu-latest + Python 3.11
  with SMOKE_SKIP_LIVE=1, then runs node scripts/validate.mjs.
  Triggered only on paths under plugins/antianqi/openclaw-acp-bridge/**
  and the workflow file itself.
• README.md + skills/*/SKILL.md (review Add antianqi/openclaw-acp-bridge v0.1.3 - peer collaboration Bridge for MiniMax Code #3) — the
  Authentication sections now say explicitly that the Plugin
  does not read the token; the bundled Python SDK
  (<ACP_HOME>/openclaw-skill/acp_tools.py) reads
  $ACP_TOKEN or <ACP_HOME>/.acp_token and attaches the
  Authorization header. The Skills only call SDK functions.
• acp-task-dispatch/SKILL.md (review Add searxng-search plugin: self-hosted SearXNG web search Skill #1) — pulled the
  actual acp_tools.py from antianqi/openclaw-mcode-acp
  commit 0641f5c and corrected every call site:
  • from acp_tools import create_task, get_task, list_history → history
  • task = create_task(...) then task["task_id"] → task_id = create_task(...) (returns a string, not a dict)
  • terminal-state predicate ("completed", ...) → ("succeeded", ...) — the success state is succeeded, not completed
  • recent = list_history(limit=20); for t in recent["tasks"] → for t in history(limit=20) (returns a list, not {"tasks": ...})
• acp-collab/SKILL.md (review Add skill-bridge plugin (antianqi/skill-bridge) v0.2.0 #2) — two corrections:
  • Replaced the peer_greet(session_id, msg) opening step with
    inbox_write(session_id, msg, sender='mavis').
    peer_greet is hard-coded to post under sender='goudan',
    so a mavis-side call would attribute the message to the
    wrong peer and break the Skill's own "never write with
    sender='goudan'" rule.
  • The "answer goudan's question" loop treated inbox_read as
    a mapping. It returns a list directly. Simplified the
    loop accordingly.
• README.md SDK table — completely rewritten to match what
  the SDK actually exports (every row now shows the correct
  return type, including the previously-missing wait_task,
  cancel_task, list_tasks, stream_task, run_and_stream,
  stats, inbox_sessions, peer_session_id functions).
  Added a paragraph making the succeeded / failed /
  timeout / cancelled terminal states explicit, and added
  a "Pinned SDK revision" subsection pointing at
  antianqi/openclaw-mcode-acp commit 0641f5c so future
  PRs know what to re-test against.
• skills/*/SKILL.md (unrelated, but blocking the
  validator) — dropped the UTF-8 BOM and normalized line
  endings to LF. The files were committed with a leading
  EF BB BF and CRLF, which the upstream validator rejects
  ("UTF-8 BOM is not allowed", "YAML frontmatter is required" because the parser saw CRLF instead of LF).

Local verification

• node scripts/validate.mjs reports OK plugin antianqi/openclaw-acp-bridge.
• SMOKE_SKIP_LIVE=1 python scripts/smoke.py reports 8/8 PASS.

Ready for another pass.

[hetaoBackend]

Please address these blocking issues before merge:

1. scripts/smoke.py now restricts the initial ACP_BASE_URL to loopback, but Check 5 still uses urllib.request.urlopen with the bearer token and follows redirects. A loopback server can redirect to another local endpoint that captures ACP_TOKEN; use a no-redirect opener (or otherwise enforce the final origin) for the token-bearing requests.
2. The README says the CI workflow installs/tests the SDK from pinned commit 0641f5c, but .github/workflows/openclaw-acp-bridge-smoke.yml only checks out this repository and sets up Python; it does not install or expose ACP_HOME/that pinned SDK. Align the workflow and the claim, or remove the claim.

The current [code]smith check is SKIPPED, so please add a real regression test for the redirect case.

[antianqi]

Both blocking issues are fixed at 9a0939b.

What changed

#	Reviewer finding	Fix
1	scripts/smoke.py Check 5 used urllib.request.urlopen with the bearer token. Even with the loopback host allowlist, the same-host server could 302 to a different local origin and the default opener would follow the redirect while keeping the Authorization header attached, leaking $ACP_TOKEN to the capture endpoint.	New scripts/smoke_helpers.py exposes NoRedirectHandler (overrides http_error_301/302/303/307/308) and build_no_redirect_opener() (strips the default HTTPRedirectHandler from BOTH opener.handlers AND the dispatch dict opener.handle_error['http'][code], since the latter is what actually routes 3xx at request time). Check 5 now uses this opener for every token-bearing request; a 3xx is surfaced as HTTPError and the test reports [FAIL] no-redirect policy was not applied.
2	The README claimed the CI workflow installs the SDK from a pinned commit of antianqi/openclaw-mcode-acp, but the workflow only checked out this repo. Check 1-3 were always skipped.	The workflow now does an explicit actions/checkout of antianqi/openclaw-mcode-acp @ 0641f5c (declared in the workflow's env.ACP_SDK_REF so future bumps are visible) into a temporary path, then exports it as $ACP_HOME before running smoke.py. The README's "Pinned SDK revision" and "CI" sections now match what the workflow actually does.

Real regression test for the redirect case

New scripts/test_no_redirect.py (also wired into the CI workflow) is not a static check — it stands up two local HTTP servers on free loopback ports:

• frontend: 302 to capture for /acp/inbox/write, 200 for /acp/inbox/read.
• capture: records every Authorization header it receives.

The test drives the smoke test's opener against frontend with a fake token and asserts:

1. The 302 is surfaced as HTTPError 302 (no follow).
2. The 200 on GET completes without contacting capture.
3. capture recorded 0 requests with the fake token.

This proves the redirect path cannot leak the token even when the original server turns hostile on the same machine — the test would fail loudly if NoRedirectHandler was ever replaced or bypassed.

scripts/smoke.py's body was wrapped in a main() function so the regression test can import smoke_helpers without triggering the full check sequence on import.

Verification

• python scripts/test_no_redirect.py — 3/3 PASS (302 refused, capture clean, GET 200).
• SMOKE_SKIP_LIVE=1 python scripts/smoke.py — 8/8 PASS (Check 1, 2, 4, 5 degraded to "skipped"; static checks 3 and 6 still run).

Ready for another review pass.

[hetaoBackend]

Request changes: the new no-redirect regression only exercises the local urllib opener inside scripts/smoke.py (the token-bearing calls at lines 165-197). The actual Skills import acp_tools from the external ACP_HOME/openclaw-skill checkout (skills/acp-collab/SKILL.md lines 28-37 and acp-task-dispatch/SKILL.md lines 23-27), and this Plugin neither ships nor validates that SDK request implementation. Therefore the real token-bearing path used by the Plugin is still not covered by the claimed redirect guarantee. Please either pin/ship a tested SDK revision whose HTTP client refuses redirects and add a test that invokes that real SDK against a redirector/capture server, or narrow the README/CI claim so it does not present the smoke-only helper as protection for runtime requests. Also note that CI sets SMOKE_SKIP_LIVE=1, so the authenticated path remains untested there.
