Releasing toolnexus

Publishing is outward-facing and irreversible: a version number can never be reused on npm, PyPI, NuGet, Maven Central, Hex, Clojars or crates.io. This skill exists because the obvious signals lie in both directions — a green workflow can ship nothing, and a red workflow can be a complete success.

The two rules that override intuition

1. A green run is not evidence a package landed. ADR-0012 exists because NuGet and Maven have reported success without publishing. Always verify from outside, as a consumer would (step 6).

2. A red run is not evidence of failure. Re-dispatching a completed release makes the already-published legs refuse a duplicate — npm cannot publish over the previously published versions, Clojars 403 redeploying non-snapshots is not allowed. That is immutability working. Read the job list, not the conclusion.

Never do these

• Never publish unless the owner asked in this conversation. "Is it ready?" is a question, not authorization.
• Never release unmerged code. The release is cut from main after the PR merges.
• Never bump one port "to unblock". preflight refuses it, and that refusal is the point.
• Never turn ENABLE_* variables off to isolate one registry. A disabled leg is skipped silently; forgetting to restore it makes a future release quietly incomplete. Accept a red run whose only real job succeeds instead.
• Never print, log, echo or paste a registry token. They are use-only env vars read at the point of use.

Steps

1. Run the readiness gate

.claude/skills/release/scripts/check-release-readiness.sh <version>

It replicates release.yml's preflight locally and adds the check preflight does not have — that the versioned install coordinates in the docs match the release. It checks: seven manifests in lockstep (golang has none — it releases as a tag), docs install coordinates, a dated ## <version> changelog section with a fresh ## Unreleased above it, clean tree on main in sync with origin, the tag being free, all eight ENABLE_* gates (including ENABLE_CRATES), and licensing.

The licensing check covers what actually drifts: a LICENSE file in every port, THIRD-PARTY-NOTICES.md present, the elixir Hex package still shipping LICENSE in its files: list, and every declared dependency appearing in the notices — the real failure mode being a dependency added and never listed. It matches names only across shipped configurations (test/dev deps are excluded: java testImplementation, elixir excoveralls/ex_doc). It does not verify the license of each pinned version — that needs a per-ecosystem resolver, and the notices file instead states the rule: re-verify on add/remove/major-version change, because an upstream can relicense between releases (ModelContextProtocol for C# is Apache-2.0 while the other MCP SDKs are MIT).

Fix every ✗ before continuing.

2. Choose the version honestly

Patch for pure fixes. Minor when observable behavior moves, even without an API break — a consumer pinning ~0.13.0 should not silently inherit changed output. If in doubt, ask; it cannot be undone.

3. Bump and roll, as one commit on its own branch

All seven manifests (js, python, csharp, java, elixir, clojure/build.clj, rust/Cargo.toml) to the same version, and ## Unreleased → ## X.Y.Z — YYYY-MM-DD with a fresh empty ## Unreleased above it. Update the docs install coordinates in the same commit — README.md, java/README.md, clojure/README.md, elixir/README.md, clojure/examples/*/deps.edn, rust/README.md, site/src/content/docs/install.mdx, quickstart.mdx, api/clojure.mdx, and the in-process-client recipe sources site/recipes/in-process-client/* (then run node site/scripts/sync-recipes.mjs, or CI's "API reference coverage" fails on stale pages).

Leave historical statements alone: "on Clojars since v0.13.0", "Relay ships in golang/ as of 0.12.0", and docs/performance-benchmarks.md's "Versions measured". Rewriting those falsifies the record.

3b. Know that the release gates on a LIVE model run

release.yml has a live-scenarios job — golang only, behind the live build tag — that runs the harness scenarios against a real model on OpenRouter before any registry leg publishes (every leg needs: [preflight, live-scenarios]). The other six ports prove parity hermetically in CI; this proves the mechanisms actually work against a provider before anything ships.

It needs OPENROUTER_API_KEY in the prod environment. If it is missing the whole release fails at the gate, before publishing — which is the correct failure, but check it is present before cutting rather than discovering it mid-release. Run the same suite locally first:

cd golang && OPENROUTER_API_KEY=… go test -tags live -run TestLive -v ./...

The tag keeps these out of normal CI: go test ./... never sees them, and the tests skip cleanly when the key is absent.

4. Open the PR and wait for every CI job

"Docs examples (eight ports)" legitimately takes 13–18 minutes. It is not hung. Do not merge on all-but-one.

5. Merge, then cut the Release

The GitHub Release is the trigger. Its body is the changelog section — extract it, never hand-write a second account:

gh release create v<version> --title "v<version>" --notes-file <extracted-section> --target main

6. Verify every registry from outside

Do this even when the run is green. Do not report a release as done without it.

npm view toolnexus version
curl -s https://pypi.org/pypi/toolnexus/json | python3 -c 'import sys,json;print(json.load(sys.stdin)["info"]["version"])'
curl -s https://api.nuget.org/v3-flatcontainer/toolnexus/index.json | python3 -c 'import sys,json;print(json.load(sys.stdin)["versions"][-1])'
curl -s https://repo1.maven.org/maven2/io/github/muthuishere/toolnexus/ | grep -oE '0\.[0-9]+\.[0-9]+' | sort -uV | tail -1
curl -s https://clojars.org/api/artifacts/net.clojars.muthuishere/toolnexus | python3 -c 'import sys,json;print(json.load(sys.stdin)["latest_version"])'
curl -s https://hex.pm/api/packages/toolnexus | python3 -c 'import sys,json;print(json.load(sys.stdin)["releases"][0]["version"])'
curl -s https://crates.io/api/v1/crates/toolnexus | python3 -c 'import sys,json;print(json.load(sys.stdin)["crate"]["max_version"])'
git ls-remote --tags origin | grep golang/v<version>

crates.io needs a User-Agent-friendly client; if the API refuses a bare curl, add -A toolnexus-release-check. Verify a consumer build too: cargo new t && cd t && cargo add toolnexus@<version> tokio -F tokio/full && cargo build.

Indexing lag is normal and is not failure: NuGet ~5 min, Maven Central ~15–20 min. Poll before concluding anything. Clojars is net.clojars.muthuishere, not io.github.muthuishere.

7. Marketing

Run the marketing skill for this version (drafts only; the owner posts). It builds ~/.marketing/toolnexus/<version>/ from the changelog section and the standing page.

8. If a leg failed

Diagnose first — gh run view <id> --log-failed. Credential failures (API key revoked, 401, 403) are owner fixes; report them and file an issue rather than retrying blindly.

To re-publish one leg after the fix: gh workflow run release.yml --ref main -f version=<version>. This re-runs everything. Expect the already-published legs to fail on duplicate rejection and the run to go red — check that the leg you cared about says success, then verify from outside.

Registry facts worth not re-deriving

Report honestly

State which registries are confirmed from the registry, which are still indexing, and which failed and why. A partial release is a partial release; say so, and say what a consumer of the lagging port gets in the meantime.
