What it does

Plugin Improve is an agent skill from glittercowboy/plugin-freedom-system. Fix bugs, add features to completed plugins. Includes versioning, backups, regression testing, changelog automation. Auto-detects deep-research handoffs to preserve investigation context. Trigger terms - improve, fix, add feature, modify plugin, version bump, rollback

Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files and assets (for example `assets/backup-template.sh`, `assets/notes-template.md` and `assets/rollback-template.sh`).

It sits in Development, covering Deep research, Backup and disaster recovery and Debugging. The repository describes itself as: AI-assisted JUCE plugin development system for MacOS by TÂCHES.

When your agent uses it

  • Terms - improve
  • Tasks that involve Deep research
  • Tasks that involve Backup and disaster recovery

Example prompts

  • “/plugin-improve”

Requirements

  • A Bash shell
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Task

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Specificity Detection
  2. 2: Headless Plugin Detection (GUI-Optional Flow)
  3. 3: Clarification Questions (If Specific)
  4. 4: Decision Gate
  5. 45: Research Detection
  6. 5: Investigation (Auto-Tiered)
  7. 9: Backup Verification
  8. Pre-Implementation Checks
  9. Verify Rollback Path
  10. Implementation
  11. CHANGELOG Update
  12. Build and Test

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:

    • Read
    • Write
    • Edit
    • Bash
    • Task

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Plugin Improve loads about 4.2k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 1,496 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~4.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~14k

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: Read, Write, Edit, Bash, Task

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 1,496 words (~4,178 tokens).

“Purpose: Make changes to completed plugins with versioning, backups, changelog automation, and root cause investigation.”
