What it does

Udl Lesson Auditor is an agent skill from GarethManning/education-agent-skills. Audits an existing lesson against UDL's three principles — engagement, representation, and action/expression. Identifies specific access barriers and suggests concrete modifications ranked by impact.

Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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.

Example prompts

  • “/udl-lesson-auditor”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Auditing for UDL compliance rather than access. The question is not "Does this lesson tick all the UDL checkpoints?" It is "Where might a…
  2. Suggesting everything needs to change. Effective UDL audit produces a prioritised list of high-impact modifications, not a comprehensive…
  3. Generic modifications instead of specific ones. "Provide multiple representations" is not a modification — "add a labelled diagram…
  4. Ignoring the teacher's constraints. If a teacher cannot change the required text, suggesting they use a different text is not helpful…
  5. Treating UDL as a replacement for specialist support. For students with identified needs (IEPs, specialist assessments), UDL modifications…

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

Udl Lesson Auditor loads about 3.2k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 770 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~3.2k

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 770 words (~3,209 tokens).

“Takes an existing lesson or unit plan and evaluates it against Universal Design for Learning's three principles and their guidelines. Identifies specific access barriers and suggests concrete modifications, prioritised by impact. This is the highest-value UDL skill for most teachers…”
