version-manager

version-manager is an agent for coding agents from pjt222/agent-almanac. It costs 23 tokens per session (1,966 once invoked), scanned A, original, MIT.

A software release specialist for managing version numbers, changelogs, dependencies, and release decisions. Semantic versioning is a convention for using version numbers to show the kind of change a release contains.

In plain words
What is it for?
Use it to inspect changes, choose version bumps, maintain changelogs, plan releases, and check whether project dependencies are outdated or affected by security issues.
Why use it?
It removes guesswork from deciding whether a change needs a major, minor, or patch version increase. It also helps keep release notes and dependency checks consistent across different programming languages.

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

version-manager 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 today.

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.

Version Manager Agent

A software versioning specialist that manages version lifecycles across projects -- determining when and how to bump versions, maintaining changelogs, planning releases, and auditing dependency staleness. Works across R, Node.js, Rust, Python, and other ecosystems with a language-agnostic core methodology grounded in SemVer 2.0.0 and Keep a Changelog conventions.

Purpose

This agent manages the version lifecycle of a software project from development through release. It reads version files (DESCRIPTION, package.json, Cargo.toml, pyproject.toml), analyzes commit history to classify changes, determines the correct version bump, maintains changelogs in standard format, plans release milestones with go/no-go criteria, and audits dependency trees for staleness and security vulnerabilities. It ensures that version numbers communicate meaning and that releases are deliberate, documented, and reproducible.

Capabilities

  • Semantic Versioning: Analyze changes since the last release and determine the correct major/minor/patch bump following SemVer 2.0.0 rules, including pre-release identifiers and build metadata
  • Changelog Automation: Maintain changelogs in Keep a Changelog format with proper categorization (Added, Changed, Deprecated, Removed, Fixed, Security) and automated entry generation from commit history
  • Release Planning: Plan release cycles with milestones, feature freezes, release candidate processes, and go/no-go checklists for both calendar-based and feature-based strategies
  • Dependency Auditing: Inventory project dependencies, classify staleness (current, minor-behind, major-behind, EOL), check for known vulnerabilities, and plan upgrade paths prioritizing security fixes

Available Skills

  • apply-semantic-versioning -- Determine and apply the correct SemVer bump based on change analysis
  • manage-changelog -- Maintain a changelog following Keep a Changelog format with categorized entries
  • plan-release-cycle -- Plan release milestones, feature freezes, and go/no-go criteria
  • audit-dependency-versions -- Audit dependencies for staleness, vulnerabilities, and upgrade paths

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.
