Publish

Publish a package from this monorepo via GitHub release. The publish workflow always publishes to all supported registries for the package (see table below) — there is no way to select individual registries.

Arguments are optional and positional — any can be omitted:

• package: mcp-wallet-signer, browser-evm-signer, or browser-tron-signer
• bump: patch, minor, or major

Note: wallet-signer-core is an internal-only monorepo package — it's inlined into both chain packages by dnt, so no consumer would install it directly from npm. Don't publish it.

Inferring missing arguments

When arguments are omitted, infer them from context:

1. Package: Run git diff HEAD~3 --stat -- packages/ to find which package(s) changed recently. If exactly one, use it. If ambiguous, ask the user.
2. Bump: Recommend based on the diff (see step 2 below). Ask for confirmation.

Package details

First publish of a new package

New npm packages need a one-time manual bootstrap before the GitHub-Actions OIDC flow works. For the very first publish of a new package:

1. Build locally: cd packages/<dir> && deno task build:npm
2. From the user's shell: cd packages/<dir>/npm && npm login && npm publish --provenance --access public (interactive — user runs)
3. JSR (if applicable): cd packages/<dir> && deno publish --allow-dirty
4. Tag the commit and push, but skip creating a GitHub release for this initial version — the publish workflow would otherwise fire on release: created and fail because the version is already on the registry.
5. Authorize the GitHub workflow on each registry — do this immediately, even though the next release may be weeks away:
   • npm Trusted Publisher (https://www.npmjs.com/package/<npm-name>/access → "Trusted Publishers"): add provider GitHub Actions, owner nikicat, repo mcp-wallet-signer, workflow publish.yml, environment blank. Without this, the workflow's npm publish --provenance fails with ENEEDAUTH — secrets.NPM_TOKEN is unset in this repo on purpose; the workflow relies entirely on OIDC.
   • JSR linked repo (https://jsr.io/<jsr-name>/settings → "GitHub repository"): set to nikicat/mcp-wallet-signer. Without this, deno publish --allow-dirty fails with actorNotAuthorized. Authorization is per-package — granting it for one package does not carry over to a sibling under the same scope.
6. The next version bump (≥ 0.x.y+1) goes through the normal workflow flow below.

Bumping the chain-pkg dep range in mcp-wallet-signer

The MCP build remaps each chain-pkg mod.ts import to an npm dependency with a fixed version range — see packages/mcp-wallet-signer/scripts/build-npm.ts, in mappings. For pre-1.0 versions, ^0.1.0 only matches >=0.1.0 <0.2.0, so a chain minor bump (0.1.x → 0.2.0) leaves the MCP package pinned to the old major-zero band and npx mcp-wallet-signer keeps installing the stale version.

When publishing mcp-wallet-signer after a chain package's minor bump, also bump the range to the new band (e.g. ^0.1.0 → ^0.2.0) and verify the built npm/package.json carries it before tagging:

grep -E '"browser-(evm|tron)-signer"' packages/mcp-wallet-signer/npm/package.json

Tag format

Tags use the monorepo convention: <npm-name>@<version> (e.g., mcp-wallet-signer@0.4.1, browser-evm-signer@0.1.4). The publish workflow parses the package name from the tag.

Steps

1. Select package

Resolve package from arguments or inference (see above).

2. Detect existing state and determine version

Before doing any work, check what's already been done so the skill can resume a partial publish:

1. Read the current version from the package's deno.jsonc (see table above for which field).
2. Find the latest released tag: git tag -l '<npm-name>@*' --sort=-v:refname | head -1.
3. Check whether a tag for the current version already exists: git tag -l '<npm-name>@<current-version>'.
4. Check whether a GitHub release already exists: gh release view <npm-name>@<current-version> 2>&1.
5. Check whether the package is already published:
   • npm: npm view <npm-name> version
   • JSR (if applicable): deno info jsr:<jsr-name>@<current-version>

Based on this state, determine the resume point:

If a full flow is needed (no tag for current version):

1. Run git log <latest-tag>..HEAD --oneline -- packages/<package-dir> to get commits since the last release.
2. If there are no commits, inform the user there's nothing new to publish and stop.
3. Recommend a bump type based on the commits:
   • patch: bug fixes, formatting, docs, dependency bumps, CI changes
   • minor: new features, new API surface, new tools/commands
   • major: breaking changes to public API, removed exports, changed behavior
4. Show the user: the commit list, your recommended bump type with reasoning, and the resulting version. Ask for confirmation.

3. Build the npm package (smoke test)

Skip this step if resuming past it.

Run from the package directory:

cd packages/<package-dir> && deno task build:npm

Verify the build succeeds before continuing.

4. Commit, tag, and push

Skip steps that are already done (e.g., if tag already exists, don't re-create it).

1. Bump the version in packages/<package-dir>/deno.jsonc.
2. If publishing mcp-wallet-signer: also bump both version fields in the root server.json (top-level and packages[0].version).
3. Stage and commit changed files with message: Bump <npm-name> version to <new-version>
4. Create a git tag: <npm-name>@<new-version>
5. Push commit and tag: git push && git push --tags

Important: Always verify the tag is on the remote before proceeding. If the tag exists locally but not on the remote, push it with git push --tags.

5. Wait for CI checks

Wait for the CI workflow to pass on the pushed commit using gh run watch $(gh run list --workflow=ci.yml --limit=1 --json databaseId --jq '.[0].databaseId') with a timeout of 5 minutes.

If CI fails, show the logs with gh run view <run-id> --log-failed and stop — do not create a release with failing checks.

6. Create GitHub release

Run:

gh release create <npm-name>@<new-version> --title "<npm-name>@<new-version>" --generate-notes

This triggers the publish.yml GitHub Actions workflow which parses the package name from the tag, builds, and publishes to all supported registries:

• npm job: always runs — builds with deno task build:npm and publishes with npm publish --provenance
• jsr job: runs only for packages with jsr: true in the workflow (currently browser-evm-signer, browser-tron-signer)

7. Wait for publish workflow

Get the run ID from gh run list --workflow=publish.yml --limit=1 and watch it with gh run watch <run-id>. Use a timeout of 5 minutes.

If the workflow fails:

1. Show the logs with gh run view <run-id> --log-failed.
2. Common failure modes — diagnose before retrying:
   • npm error code ENEEDAUTH → trusted publisher missing on npm for this package. See "First publish of a new package" step 5 — same fix applies to a package that was bootstrapped manually but never wired up for CI.
   • error: ... actorNotAuthorized from deno publish → JSR repo authorization missing for this package.
3. Once the underlying auth/setup is fixed (ask the user to do this), resume the same run instead of cutting a new tag: gh run rerun <run-id> --failed. The GitHub release is already created, so a fresh push won't re-trigger anything.

8. Verify published packages

Check all supported registries for the package:

• npm: Run npm view <npm-name> version and confirm the output matches <new-version>.
• JSR (if package supports it): Do not use deno info jsr:<jsr-name>@<new-version> from inside the workspace — Deno resolves the JSR specifier to the local workspace member and reports the in-tree source, so the check always "passes" regardless of what's actually on the registry. Hit JSR's meta API directly instead:

  curl -s "https://jsr.io/<jsr-name>/meta.json" | python3 -c "import sys, json; print(list(json.load(sys.stdin).get('versions', {}).keys()))"
  

  Confirm <new-version> appears in the list.
• If any check fails, warn the user.
