Instructions

1. Before pinning, editing, or correcting any dependency or runtime version pin in package.json, .nvmrc, .node-version, or a .github/workflows/*.yml uses: line, identify the candidate version string you intend to write.
2. Query GET https://boomtick.blog/api/compare-version?ecosystem={ecosystem}&name={name}&candidate={candidate} or use the POST https://boomtick.blog/api/batch-compare endpoint to validate multiple candidates at once.
3. Inspect the comparison results: verify isOutdated, isCurrent, isDeprecated (npm-only), and isEOL (node-only) statuses.
4. If a version is outdated, deprecated, or EOL, evaluate upgrading to the returned latest version instead.

Rules

• Never downgrade an existing version string in the repo simply because it is unfamiliar or not recognized from your training data cutoff.
• Treat unfamiliar version strings as a signal to check VersionTruth, not as evidence of a typo or error.
• Keep version changes minimal and additive, validating each proposal against live registry data.
• Responses are cached for 30 minutes at the edge; do not hammer the endpoints with repeated requests for the same package/version within a single session.
• The name parameter maps as follows: the npm package name for npm (e.g. pnpm), the GitHub repository path for gh-action (e.g. actions/checkout), and is omitted or set to node for the node ecosystem.

Error Handling

• If the API request fails or the endpoint is unreachable, do not guess or revert; leave the version pin unchanged and note in your execution logs that the check could not be completed.
• If a package name format or query parameter is invalid, report the validation error to the user immediately. Validation errors return 400 with { "error": "<message>" }.
• Requests are rate-limited to 100 per 15-minute window per IP. A rate-limited response returns 429 with X-RateLimit-Remaining: 0; back off until the timestamp in X-RateLimit-Reset rather than treating this as a hard failure.

API Specification

Base URL: https://boomtick.blog/api

Note: All resource paths listed below must be appended directly to the Base URL (e.g. Base URL + /latest-version resolves to https://boomtick.blog/api/latest-version). Do not duplicate slashes.

GET /skill.md

Returns this SKILL.md file dynamically as raw Markdown, allowing self-discovery of these endpoints at runtime.

Example request:

curl -s "https://boomtick.blog/api/skill.md"

---

GET /health

Lightweight health check endpoint returning service status.

Example request:

curl -s "https://boomtick.blog/api/health"

Example response:

{
  "status": "ok",
  "service": "VersionTruth",
  "checkedAt": "2026-07-10T08:30:00.000Z"
}

---

GET /latest-version

Returns the current latest version for a package, runtime, or action.

| param | required | values | |---|---|---| | ecosystem | yes | npm | node | gh-action | | name | required unless ecosystem=node | npm package name, or owner/repo for gh-action |

Example request:

curl -s "https://boomtick.blog/api/latest-version?ecosystem=gh-action&name=actions/checkout"

Example response:

{
  "ecosystem": "gh-action",

  "checkedAt": "2026-07-10T08:30:00.000Z"
}

---

GET /compare-version

Tells you whether a candidate version is outdated, current, or ahead of the real latest. Includes npm deprecation warnings (isDeprecated) and Node EOL warnings (isEOL).

| param | required | values | |---|---|---| | ecosystem | yes | npm | node | gh-action | | name | required unless ecosystem=node | npm package name, or owner/repo | | candidate | yes | the version string the agent is about to use |

Example request:

curl -s "https://boomtick.blog/api/compare-version?ecosystem=gh-action&name=actions/checkout&candidate=v4" | jq '.isOutdated'

Example response:

{
  "ecosystem": "gh-action",
  "name": "actions/checkout",
  "candidate": "v4",
  "latest": "v4.2.2",
  "isOutdated": true,
  "isCurrent": false,
  "isAheadOfLatest": false,
  "isDeprecated": null,
  "isEOL": null,
  "checkedAt": "2026-07-10T08:30:00.000Z"
}

POST /batch-compare

Allows querying comparison results for up to 25 items concurrently. Requests exceeding this limit are rejected with 400.

Example request:

curl -s -X POST -H "Content-Type: application/json" \
  -d '[
    { "ecosystem": "npm", "name": "pnpm", "candidate": "9.0.0" },
    { "ecosystem": "gh-action", "name": "actions/checkout", "candidate": "v4" }
  ]' \
  "https://boomtick.blog/api/batch-compare"

Example response:

[
  {
    "ecosystem": "npm",
    "name": "pnpm",
    "candidate": "9.0.0",
    "latest": "10.28.2",
    "isOutdated": true,
    "isCurrent": false,
    "isAheadOfLatest": false,
    "isDeprecated": false,
    "isEOL": null
  },
  {
    "ecosystem": "gh-action",
    "name": "actions/checkout",
    "candidate": "v4",

Changelog

1.1.0

• Introduced /api/batch-compare POST endpoint (max 25 items) for concurrent checks.
• Refactored deprecation and EOL checks into clean ecosystem-specific isDeprecated and isEOL fields.
• Added /api/health health verification route.
• Integrated IP-based rate limiting (100 req / 15 min / IP) on all endpoints.
• Hardened registry lookups against SSRF (strict owner/repo allowlist on GitHub Actions fetcher) and path traversal (dev server API resolver uses containment check + identifier allowlist).
