uvx uacp-interop

A conformance checklist proves your implementation matches your own reading of a spec. It says nothing about whether your reading and your code agree. uacp-interop exists to close that gap, and it found eleven defects, all now fixed. The greatest hits:

Three defects that all looked fine:

And the fourth, still partly open: a permissive authorization default. A bus with no ACLs routes everything, which is defensible only when every caller is a function in the same process. Inverting it outright would break every single-author use while protecting nothing, so Bus now takes trust='trusted' | 'untrusted' and refuses to construct an untrusted bus with no policy. Reaching a networked bus is now a decision rather than an omission.

Also: wippa-automations, an AI-first Zapier alternative, and wippa-opencode-agents, a portable multi-agent OpenCode configuration.

They don't share code, so it's worth being precise about the one real link:

uacp-interop vendors wippa-uacp's JSON Schemas and records the exact upstream commit in PROVENANCE.json, re-checked for drift on every run.

It deliberately does not pip install the protocol, so a conformance report can test a released spec without silently testing something newer. Tracking main is how a report ends up certifying a spec that was never published. (It's also why a fixed defect keeps showing up as a live finding until the schema is re-vendored.)

agent-protect exists because untrusted agents are dangerous; UACP exists to put agents on a shared bus.

• ✅ Designed: a bus carrying an agent the operator doesn't trust is enforceable. Bus takes an ACL set, rejects unauthorized calls with AUTHORIZATION before routing, and won't construct at all if told it's untrusted without a policy.
• ⚠️ Still missing: a cross-pipeline cost ceiling. Two well-behaved agents in a loop are bounded by nothing in the protocol, and the caller can't tell a completed pipeline from a truncated one. That's a specification gap, not an implementation bug: no amount of better code makes it conformant, because there's no claim to have failed.

Both are written up in CONFORMANCE-TESTING.md and §15.8 rather than left implicit.

I fix things in other people's projects. Three have merged.

A stale-read race in updateSnapshot. It published a new evaluation snapshot to subscribers before swapping it into the store. A client that refetched on the hint read the previous snapshot (or got a not-found for a namespace that had just been created), and because the stream had already recorded the digest, no second event followed. It stayed stale until the next flag change. One reorder fixes it. A reviewer asked for the regression test to move into the existing test file; a maintainer then extended the fix and merged v2 in. 48694cbd

uacp-interop's own methodology, pointed at something else. The maintainer of gala asked for a check that its Nix-built stdlib byte-matches the Bazel one, and supplied the shell commands. Nothing compared them, so a codegen change that genuinely moved stdlib output would leave the Nix build succeeding with a stale embedded stdlib and no signal. The prerequisite had already landed the day before, so the lane was the whole of it. 0421b5c

I could not run it — no Nix, no Bazel where I wrote it — so the body says so plainly and names the one thing a reviewer should check instead. martianoff merged it on the description, not on my verification.

A TypeError: functionArn.split is not a function crash in API Gateway authorizer validation: any CloudFormation-intrinsic arn without a name reached a string-only ARN parser. Replaced with an actionable validation error, and covered the error path, which had no test at all. czubocha merged it. fe70b85c

Interactive replies in a conversation that also held scheduled-routine results couldn't be rated, because eligibility was read from the conversation's origin instead of the individual run's. I traced the fix commit and confirmed it was an ancestor of the shipping branch; the maintainer shipped it in v0.12.4 and closed the issue thanking me for the flag. My contribution there was the diagnosis, not a patch.

gh pr merge --delete-branch deletes someone else's work. It matches the head branch by name in whatever repo your shell happens to be in. If an unrelated repo has a worktree on a same-named branch holding unpushed commits, gh removes the worktree and runs git branch -D on it — and since git branch -D bypasses git's own merged check, those commits exist only in a reflog. I reproduced it, wrote a scope guard plus an ancestry check, and got 7/7 green CI with 8 of 13 new tests failing against pristine source.

It was still the wrong contribution, and I closed it myself.

cli/cli takes external PRs only for help wanted issues with explicit Acceptance Criteria, and their AGENTS.md asks you to verify that before implementing — and to not automatically publish a comment asking for the label. The issue had needs-triage. Their own bot labelled the PR unmet-requirements twenty minutes after it opened.

The mistake that actually mattered wasn't opening it. It was that, having found the help wanted rule in CONTRIBUTING.md, I recommended a public comment as the path their docs prescribe — without having opened AGENTS.md, which forbids exactly that. Incomplete file list, not faulty reasoning. Those fail differently: faulty reasoning gets fixed, an incomplete checklist gets repeated. AGENTS.md and CLAUDE.md now get read before CONTRIBUTING.md, because an agent-facing file governs permission and CONTRIBUTING only governs the bar.

The branch is still up. If #14537 ever gets triaged into scope it's one reopen away.

Closing the case martianoff couldn't reproduce. They'd reported that a local type in their own sample shadowed an import, and it didn't happen for them. It was a self-hosting resolver that only treated a package-qualified path as a local name, so http.Get shadowed the imported http while net/http.Get did not — and their sample used the qualified form. One file, +189/−2, with the 14/14 regression test.

There's a second defect in that resolver I did not fix: a bare name with no local declaration is still handled unsoundly at step 5, and two committed examples depend on it. I flagged it as its own issue rather than quietly widening a PR that was already a maintainer request.

Transaction support, closing a help wanted that had been open four years. The mechanism existed three times over in that codebase and was not on the path a request takes: a package-level OpenTransactions map nothing read, an implemented-but-unused TransactionManager, and Insert/Update/DeleteWithTransaction already declared on the adapter interface. This is the same shape as the unwired authorization check above — correct, unit-tested, unreachable.

Wiring it was the easy half. Two defects in my own first cut made it non-functional, and I only found them by reading the bot's review rather than declaring it done: the transaction was opened on the request context, which database/sql rolls back the moment that request returns, and the commit path read its id with r.PathValue, which gorilla/mux v1.8.1 leaves empty — so every commit returned 410. My tests had missed both because they called the handlers directly instead of going through the router, and the stub ignored the context. Test and code shared one wrong assumption and so agreed with each other. Each fix has a test that fails without it.

A pending-invitation list that was permanently blank, because the page read invitations off a full-workspace payload that carries no such field, and now reads the dedicated query the invite mutations already invalidate. The regression test fails on a pristine main and the failure is the blank list itself.

Covers a response.json() failure on a non-standard 2xx — a branch that existed in the grammar and in the transpiler but had no test reaching it, so _handle_json_parse_error was unguarded. Test-only.

I read check-runs on every open PR's merge ref, reasoned that branch protection evaluates the merge ref so that must be the right thing to query, and got zero for all of them. Zero is exactly what a first-time fork's unapproved workflows also return, so "nothing has run" and "I looked in the wrong place" were indistinguishable. I wrote it up as a finding and put it on this page.

Then I needed to answer a different question — does this repo ever run CI for someone who isn't a collaborator? — and built a probe that reads the head SHA. Re-running the same measurement there:

Two fully green PRs, including the maintainer-endorsed one, and I'd written off all of them. The mistake wasn't carelessness in the reading — it was accepting a plausible justification for a measurement in place of validating it. Branch protection does evaluate the merge ref; that is true, and it is not an argument for querying it to ask "has CI run on my code". Four PRs really are silent, and that part stands.

The probe also had to be thrown away once. Its first version counted dependabot[bot] as evidence of outside contributors, and since dependabot is auto-approved in essentially every repo, it reported cli/cli, gala and kaneo all as "CI runs for forks" — every repository passing, on the strongest possible false evidence. Bots are excluded now. A gate that cannot fail is worse than no gate, because you stop looking.

Three gates now sit in front of scoring, all cheap, all of which were tested against a real failure of my own:

• Does this repo run CI for a first-time fork? Not "does it have CI" — whether a stranger's PR gets a verdict. Measured empirically against recent human outside-contributor merges, with bots excluded. A repo that won't, can't merge you.
• Is anyone already on the issue? closed_by_pull_requests alone isn't enough — on gVisor#14966 it reads zero while the issue body names an open PR fixing it. Four signals have to agree.
• Is a contribution even admissible? AGENTS.md and CLAUDE.md first, then CONTRIBUTING.md, then the PR's own labels. A maintainer bot's unmet-requirements is a recorded verdict, and it outranks my reading of their docs.

The third gate exists because the first two passed and I still got it wrong — see the cli/cli entry above. The one repo that did run my CI is also the one with the strictest entry policy, and passing a CI check is not the same as being allowed in.

And the objective itself changed. Thirteen open PRs with zero merges is a failure state that looks like progress, so fame now carries weight 0.0 in the scorer. A merged PR in a mid-size repo beats an unmerged one in a famous repo, and a maintainer-endorsed task beats both. All three merges so far came from a maintainer's backlog, not an issue feed — which is also why a fresh-sorted sweep found nothing available in roughly 12,800 issues across six attempts. Fresh means a competent maintainer just filed it and is already on it.
