At a glance

Verify that matterbridge and all Matterbridge workspace packages are aligned on the npm latest and dev tags.

  • Calls npm

What it does

Verify npm Alignment is an agent skill from Luligu/matterbridge. Verify that matterbridge and all Matterbridge workspace packages are aligned on the npm latest and dev tags. v.1.0.0

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with npm. The repository describes itself as: Matterbridge plugin manager for Matter. The licence is Apache-2.0.

Example prompts

  • “/verify-npm-alignment”

What it can do on your machine

Read from SKILL.md and the folder at commit 857fd9b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Verify npm Alignment loads about 839 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 415 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~839

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Verify that matterbridge and all Matterbridge workspace packages are aligned on the npm latest and dev tags. v.1.0.0

Verify npm latest and dev tag alignment for Matterbridge packages

Verify that the published Matterbridge packages on npm are aligned for both the latest and dev dist-tags.

Scope:

  • Use package.json to discover the root package name and the workspace manifest paths.
  • Check the root matterbridge package and every real workspace package listed in the root workspaces array.
  • Read each workspace package name from its package.json; do not hard-code the workspace package list.
  • Ignore mock package manifests under packages/core/src/mock/**.
  • Exclude apps/frontend/package.json because @matterbridge/frontend is versioned and published independently. Include it only when explicitly requested.

Execution rules:

  • Query the npm registry directly. Do not infer published versions from local manifest versions, lockfiles, release notes, or Git tags.

  • Do not run repository build, test, publish, or automation scripts.

  • For each package, query the exact version selected by both dist-tags, equivalent to:

    bash
    npm view <package-name>@latest version
npm view <package-name>@dev version

  • Treat the published matterbridge@latest version as the expected version for every in-scope package's latest tag.

  • Treat the published matterbridge@dev version as the expected version for every in-scope package's dev tag.

  • Require exact version equality, including any prerelease suffix such as -dev-YYYYMMDD-abcdef0.

  • Do not compare latest with dev; alignment is evaluated independently within each tag.

  • Treat a missing package, missing dist-tag, empty response, invalid version, authentication error, network error, or npm registry error as a verification failure. Report the error and do not silently skip that package.

  • Do not modify package metadata, publish packages, or move npm dist-tags.

Checks:

  • Verify every in-scope package at latest exactly matches matterbridge@latest.
  • Verify every in-scope package at dev exactly matches matterbridge@dev.
  • Verify every workspace listed by the root manifest was checked for both tags.
  • If arguments name a subset of packages or one tag, limit the registry queries to that requested scope while still using the corresponding matterbridge tag as the reference.
Show full SKILL.md (120 more words)Show less

Output requirements:

  • Report the npm registry used for the queries.
  • Report matterbridge@latest and matterbridge@dev first, unless the requested scope contains only one tag.
  • Provide a concise table with one row per package and columns for package, latest, dev, and status.
  • Mark a package aligned only when each checked tag exactly matches the corresponding matterbridge reference version.
  • List every mismatch with the package name, tag, current published version, and expected version.
  • List registry/query failures separately from version mismatches.
  • If everything matches, explicitly state that matterbridge and all in-scope Matterbridge workspace packages are aligned on both latest and dev.
  • If only a subset was requested, state exactly which packages or tags were not checked.
  • Do not modify files or npm registry state.
