What it does

Squad Version Check is an agent skill from kubefleet-dev/kubefleet. Internals of how @bradygaster/squad-cli stamps its version, how squad upgrade works (what it preserves vs overwrites), and how to probe the npm registry for the latest version from a coordinator prompt.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud. It works with npm. The repository describes itself as: KubeFleet is an open-source Kubernetes multi-cluster application management solution. The licence is Apache-2.0.

When your agent uses it

  • DevOps & Cloud work in your project

Example prompts

  • “Use the squad-version-check skill to internal of how @bradygaster/squad-cli stamps its version, how squad upgrade works (what it preserves vs…”
  • “/squad-version-check”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. HTML comment: <!-- version: {version} --> (must be on the line immediately after frontmatter ---)
  2. Identity line: - Version: {version}
  3. Greeting instruction: backtick-quoted Squad v{version}

What it can do on your machine

Read from SKILL.md and the folder at commit ea05fcb. 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
    • node
    • pnpm
    • yarn

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

  • Network

    No URLs in SKILL.md. Its commands use npm, pnpm and yarn, 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

Squad Version Check loads about 1.6k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 540 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

SKILL: Squad CLI Internals — Version Stamping & Upgrade Mechanics

Confidence: medium Discovered by: Data Date: 2026-05-26 Validated in: Issue #1173 recon (bradygaster/squad)

What This Skill Covers

Reusable knowledge about how @bradygaster/squad-cli stamps its version into squad.agent.md, how squad upgrade works, what it preserves vs. overwrites, and how to probe the npm registry for the latest version from a coordinator prompt.

Package & Registry Facts

  • Package name: @bradygaster/squad-cli
  • Registry: npm (public)
  • CLI binary: squad (registered via package.json#bin.squad)
  • Node version requirement: Node ≥22.5.0 (ESM-only codebase)

Version Stamping Mechanism

Source file: dist/cli/core/version.js

Three functions:

getPackageVersion()

Walks up from the compiled JS file to find package.json. Returns pkg.version. Works from both dist/cli/core/version.js and a bundled root cli.js. Returns '0.0.0' as fallback if not found.

stampVersion(filePath, version)

Mutates squad.agent.md in three places:

  1. HTML comment: <!-- version: {version} --> (must be on the line immediately after frontmatter ---)
  2. Identity line: - **Version:** {version}
  3. Greeting instruction: backtick-quoted `Squad v{version}`

Called by: both init and upgrade — after copying the template to the destination.

readInstalledVersion(filePath)

Reads the stamped version back from squad.agent.md:

  1. First tries HTML comment format: /<!-- version: ([0-9.]+(?:-[a-z]+(?:\.\d+)?)?) -->/
  2. Falls back to old frontmatter format: /^version:\s*"([^"]+)"/m
  3. Returns '0.0.0' on any error

squad upgrade Behavior

Source file: dist/cli/core/upgrade.js

What gets overwritten:
  • squad.agent.md — full overwrite from template, then stampVersion()
  • Files with overwriteOnUpgrade: true in TEMPLATE_MANIFEST: casting JSON files, template .md files, copilot-instructions.md (if @copilot enabled)
  • GitHub Actions workflows — from templates/workflows/; non-npm projects get type-aware stubs
  • Runs runMigrations() after file copy
What is PRESERVED:
  • team.md, routing.md, decisions.md, ceremonies.md (user-owned)
  • agents/*/history.md (individual agent memory)
  • .squad/config.json — never touched; stateBackend survives intact
  • User-added files not in TEMPLATE_MANIFEST
Self-upgrade path (selfUpgradeCli()):

Detects npm/pnpm/yarn via npm_execpath and npm_config_user_agent. Runs:

  • npm: npm install -g @bradygaster/squad-cli@latest
  • pnpm: pnpm add -g @bradygaster/squad-cli@latest
  • yarn: yarn global add @bradygaster/squad-cli@latest Use @insider tag for insider builds.
compareSemver(a, b) utility (in upgrade.js):

Returns -1/0/1. Handles pre-release: strips pre-release for base comparison, then treats pre-release as less than release (e.g., 0.9.5-insider.1 < 0.9.5). Can be ported directly if needed in prompt logic.

.squad/config.json — What It Holds

json
{
  "version": 1,
  "stateBackend": "worktree"
}

Other optional fields added by the coordinator at runtime:

  • defaultModel — global model override for all agent spawns
  • agentModelOverrides.{agentName} — per-agent model override

The file is read-only from the upgrade path's perspective. Only the coordinator writes to it (for model preferences).

Version-Check Probe (npm Registry)

Use this one-liner from inside a coordinator prompt to fetch dist-tags:

npm view @bradygaster/squad-cli dist-tags --json
  • Timeout: 5 seconds. If no response within 5 seconds, abandon and show normal greeting.
  • On success: extract dist-tags[channel] (e.g., dist-tags["insider"]).
  • On any error (network failure, registry unreachable, parse error): show normal greeting.

Upstream OS-Specific Cache

The CLI (self-update.ts) writes latest version info to an OS-specific path with a 24h TTL.

One-liner to read the upstream cache:

node -e "const p=require('path'),o=require('os');const b=process.env.APPDATA||(process.platform==='darwin'?p.join(o.homedir(),'Library','Application Support'):p.join(o.homedir(),'.config'));const f=p.join(b,'squad-cli','update-check.json');try{const d=JSON.parse(require('fs').readFileSync(f,'utf8'));const age=Date.now()-d.checkedAt;if(age<86400000)console.log(JSON.stringify(d));else console.log('STALE')}catch{console.log('MISS')}"

Output semantics:

  • Valid JSON {"latestVersion":"X.Y.Z","checkedAt":N} → cache hit; use latestVersion
  • STALE → cache expired (older than 24h); treat as no data
  • MISS → cache missing or corrupt; treat as no data

OS-specific cache path:

  • Windows: %APPDATA%\squad-cli\update-check.json
  • Linux: ~/.config/squad-cli/update-check.json
  • macOS: ~/Library/Application Support/squad-cli/update-check.json

Repo-Local Cache Convention: .squad/.cache/version-check.json

Used by coordinator for insider/preview channels (the upstream cache only stores latest).

Schema:

json
{
  "checkedAt": "2026-05-26T14:13:28.492Z",
  "currentVersion": "0.9.6-insider.2",
  "channel": "insider",
  "channelVersion": "0.9.7-insider.1"
}

TTL: 24 hours from checkedAt. Gitignore: .squad/.cache/ is listed in .gitignore — cache files are never committed.
