When your agent uses it
- Preparing to teach unfamiliar content
- Improving teaching of hard topics
Example prompts
- “/pedagogical-content-knowledge-developer”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- PCK Diagnosis
- Content Knowledge Foundations
- Student Misconceptions Map
- Pedagogical Representations
- Disciplinary Thinking Standards
- Dispositional PCK
- Developmental Action Plan
What it can do on your machine
Read from SKILL.md and the folder at commit 6bbbce4. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Pedagogical Content Knowledge Developer loads about 11k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 3,811 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,811 words (~10,684 tokens).
“Takes a description of what a teacher is about to teach and their background, diagnoses their likely pedagogical content knowledge gaps for that specific topic, and produces a development plan to close those gaps before teaching begins. Shulman's (1986) foundational…”
