It sits in Productivity & Automation, covering Task management. The repository describes itself as: Marketplace repo for Claude Code Plugins.

When your agent uses it

  • Updating task tracking
  • Adding features to roadmap
  • Modifying project documentation

Example prompts

  • “/master-plan-manager”

Workflow steps

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

  1. Status Updates
  2. Adding New Items
  3. Completing Items
  4. ID Format

What it can do on your machine

Read from SKILL.md and the folder at commit b643305. 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:

    • 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

Master Plan Manager loads about 1k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 280 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 280 words (~1,042 tokens).

“Intelligent management of MASTER_PLAN.md files with comprehensive safety measures.”
