What it does
Release Plugin is an agent skill from deusXmachina-dev/memorylane. Deploy the MemoryLane Claude Code plugin by verifying only plugin/marketplace files changed, bumping the plugin version, then committing and pushing.
Its SKILL.md is about 400 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 Agent Workflows, covering Hooks and plugins. The licence is GPL-3.0.
When your agent uses it
- Tasks that involve Hooks and plugins
Example prompts
- “/release-plugin”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 16abbe0. 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:
gitnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and npm, 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
Release Plugin loads about 403 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 172 words of instructions outside code blocks.
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.md

- Deploy the MemoryLane Claude Code plugin by verifying only plugin/marketplace files changed, bumping the plugin version, then committing and pushing.
Deploy Plugin
Ship a new version of the MemoryLane Claude Code plugin.
Allowed paths
Only these paths may have changes when deploying the plugin:
plugins/memorylane/
.claude-plugin/Any changes outside these paths must be committed or stashed separately before deploying.
Steps
1. Verify clean scope
Run git status and git diff --name-only to list all modified, staged, and untracked files.
If any changed file falls outside the allowed paths listed above, stop immediately and tell the user:
Some changes are outside the plugin directory. Please commit or stash them before deploying the plugin.
List the offending files so the user can act on them.
2. Read current plugin version
Read plugins/memorylane/.claude-plugin/plugin.json and note the current "version" value.
3. Bump the version
Increment the patch number by default (e.g. 0.6.0 → 0.6.1). If the user specified a version or bump level (major/minor/patch), use that instead.
Update the "version" field in plugins/memorylane/.claude-plugin/plugin.json.
4. Format
npm run format5. Commit
Stage only plugin/marketplace files:
git add plugins/memorylane/ .claude-plugin/
git commit -m "plugin: v<new-version>"6. Push
git push origin HEAD7. Confirm
Print the new version and the pushed branch name so the user can verify.
