What it does
Sheltered Instruction Lesson Modifier is an agent skill from GarethManning/education-agent-skills. Modify a lesson plan using SIOP sheltered instruction principles to support language learners across all four skills. Use when planning lessons for classes that include EAL students.
Its SKILL.md is about 6.4k 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 Education, covering Lesson planning. The repository describes itself as: 165 evidence-grounded AI skills for teachers, school leaders and EdTech builders—pedagogy, learning science, curriculum, assessment and regeneration. Claude, Codex and Hermes.
When your agent uses it
- Planning lessons for classes that include EAL students
- Tasks that involve Lesson planning
Example prompts
- “/sheltered-instruction-lesson-modifier”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- First, I enter the mouth. The mouth _ me by _.
- Next, I travel down the oesophagus. The oesophagus _ me by _.
- Then, I arrive in the stomach. The stomach _ me by _.
- After that, I move into the small intestine. The small intestine _ from me by _.

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
Sheltered Instruction Lesson Modifier loads about 6.4k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 2,330 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 2,330 words (~6,417 tokens).
“Takes a content lesson plan and modifies it using the SIOP (Sheltered Instruction Observation Protocol) model principles, adding explicit language objectives, building background knowledge, making input comprehensible, structuring meaningful interaction, and providing opportunities for practice and application — all while…”
