What it does
Pm Teaching Mode is an agent skill from bobmatnyc/claude-mpm. Comprehensive teaching templates and progressive disclosure patterns for PM teacher mode
Its SKILL.md is about 4.4k 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 Development. It works with Git. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.
When your agent uses it
- Development work in your project
Example prompts
- “/pm-teaching-mode”
Requirements
- Python 3
- Node.js
- A credential in API_KEY
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Revoke the compromised keys IMMEDIATELY
- Generate new keys
- Use git filter-branch or BFG Repo-Cleaner to remove from history
- Force push (dangerous - coordinate with team)
What it can do on your machine
Read from SKILL.md and the folder at commit 25203d3. 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:
gitcurlpipnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, curl, pip 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 these keys or tokens, usually read from environment variables:
API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pm Teaching Mode loads about 4.4k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 1,837 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.
- NoteMentions a .env fileSKILL.md:20
# 1. Create .env - NoteMentions a .env fileSKILL.md:21
echo "API_KEY=your_key_here" > .env - NoteMentions a .env fileSKILL.md:24

- ❌ Committing .env to git - NoteMentions a .env fileSKILL.md:39
**Why We Use .env Files**: - NoteMentions a .env fileSKILL.md:45
1. Create `.env` in project root - NoteMentions a .env fileSKILL.md:47
3. Add `.env` to `.gitignore` - NoteMentions a .env fileSKILL.md:52
git status # .env should NOT appear - NoteMentions a .env fileSKILL.md:53
git log --all -- .env # Should return nothing
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,837 words (~4,384 tokens).
“ELI5: API key = house key. Anyone with it can pretend to be you.”
