bump-plugin-version

A workflow for updating plugin version numbers across the Agent Alchemy project ecosystem. It also checks for mismatched versions, records the change, and creates a standard commit.

In plain words
What is it for?
Selecting plugins, choosing a version-bump level, resolving version differences, adding a changelog entry, and committing the completed update.
Why use it?
It prevents different version locations from getting out of sync and guides the required choices and confirmations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bump-plugin-version scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 526 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bump Plugin Version

Automate version bumps across the Agent Alchemy ecosystem. Scans 5 version locations per plugin, detects drift, applies consistent updates, adds a CHANGELOG entry, and creates a conventional commit.

CRITICAL: Complete ALL 6 phases. The workflow is not complete until Phase 6: Commit is finished. After completing each phase, immediately proceed to the next phase without waiting for user prompts.

Critical Rules

AskUserQuestion is MANDATORY

IMPORTANT: You MUST use the AskUserQuestion tool for ALL questions to the user. Never ask questions through regular text output.

  • Plugin selection -> AskUserQuestion
  • Bump level selection -> AskUserQuestion
  • Drift resolution -> AskUserQuestion
  • Confirmation prompts -> AskUserQuestion

Text output should only be used for:

  • Displaying progress updates between phases
  • Presenting inventory tables and drift reports
  • Phase transition markers

If you need the user to make a choice or provide input, use AskUserQuestion.

NEVER do this (asking via text output):

Which plugins would you like to bump?
1. core-tools
2. dev-tools

ALWAYS do this (using AskUserQuestion tool):

AskUserQuestion:
  questions:
    - header: "Plugins"
      question: "Which plugins would you like to bump?"
      options:
        - label: "core-tools (0.1.1)"
          description: "Current version: 0.1.1"
        - label: "dev-tools (0.1.1)"
          description: "Current version: 0.1.1"
      multiSelect: true

Plan Mode Behavior

CRITICAL: This skill performs an interactive version bump workflow, NOT an implementation plan. When invoked during Claude Code's plan mode:

  • DO NOT create an implementation plan for how to build the bumper
  • DO NOT defer the version bump to an "execution phase"
  • DO proceed with the full workflow immediately
  • DO make file edits as normal

Phase Overview

Execute these phases in order, completing ALL of them:

  1. Discovery — Read marketplace.json, build plugin inventory with current versions
  2. Drift Check — Scan all 5 version locations for inconsistencies
  3. Selection — Choose plugins and bump level, compute new versions
  4. Bump — Edit all 5 version locations per plugin
  5. Changelog — Add entries under ## [Unreleased] in CHANGELOG.md
  6. Commit — Stage modified files and create a conventional commit

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
