What it does
Plugin Workflow is an agent skill from glittercowboy/plugin-freedom-system. Orchestrates JUCE plugin implementation through stages 1-3 (Foundation, DSP, GUI) using subagent delegation with automatic validation after each stage. Use when implementing plugins after planning completes, or when resuming with /continue command. Invoked by /implement command.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files, including reference files and assets (for example `assets/architecture.md`, `assets/continue-here-template.md` and `assets/decision-menus.json`).
It sits in Agent Workflows, covering Subagents. The repository describes itself as: AI-assisted JUCE plugin development system for MacOS by TÂCHES.
When your agent uses it
- Implementing plugins after planning completes
- Resuming with /continue command
Example prompts
- “Use the plugin-workflow skill to orchestrate JUCE plugin implementation through stages 1-3 (Foundation, DSP, GUI) using subagent delegation with…”
- “/plugin-workflow”
Requirements
- A Bash shell
- Pre-approved tools (allowed-tools): Task, Bash, Read, Write, Edit
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Load contracts in parallel (architecture.md, plan.md, parameter-spec.md, creative-brief.md)
- Read Required Reading (juce8-critical-patterns.md) once at workflow start
- Construct minimal prompt with plugin name + stage + Required Reading
- Invoke subagent via Task tool
- After subagent returns, invoke validation-agent (ALL stages 1-3)
- Execute checkpoint protocol (see references/checkpoint-protocol.md)
What it can do on your machine
Read from SKILL.md and the folder at commit e965cdd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
TaskBashReadWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Shell, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Plugin Workflow loads about 3.4k tokens when it runs, and up to ~36k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 1,380 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Task, Bash, Read, Write, Edit
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,380 words (~3,408 tokens).
“Purpose: Pure orchestrator for stages 1-3 of JUCE plugin implementation with automatic validation after each stage. This skill delegates to specialized subagents and validation-agent for continuous quality assurance.”

Can I use Plugin Workflow in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add glittercowboy/plugin-freedom-system --skill plugin-workflow -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/plugin-workflow, .gemini/skills/plugin-workflow, .github/skills/plugin-workflow and .opencode/skills/plugin-workflow in your project.
What does Plugin Workflow need to run?
Going by SKILL.md and its folder, Plugin Workflow needs a shell for the scripts in its folder. Our summary lists: A Bash shell. Its frontmatter pre-approves these tools: Task, Bash, Read, Write, Edit.
Does Plugin Workflow access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Plugin Workflow safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Plugin Workflow use?
No licence was found for Plugin Workflow or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Plugin Workflow use?
About 3.4k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 33k tokens, read only when the agent opens those files.
