release-engineer

release-engineer is an agent for Claude Code from vibeeval/vibecosystem. It costs 45 tokens per session (2,813 once invoked), scanned A, original, MIT.

A release-engineering agent for preparing software releases, choosing versions, generating changelogs, planning deployments, and preparing rollback plans. It covers strategies such as blue-green and canary deployments, where new code is introduced gradually or alongside the old version.

In plain words
What is it for?
Use it to manage release branches, choose semantic versions, create changelogs, test release candidates, plan deployments and hotfixes, manage feature flags, and define rollback steps.
Why use it?
It helps teams ship changes in a controlled way and prepare for failures. Clear versioning, testing, rollout, monitoring, and rollback plans reduce release-related risk.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is cd ~/.claude && PYTHONPATH=scripts python3 scripts/core/recall_learnings.py --query "release deployment rollback" --k 3 --text-only.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

release-engineer 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.

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.
