What it does

Udl Barrier Anticipator is an agent skill from GarethManning/education-agent-skills. Predicts access barriers in a learning task before delivery, given a learner variability profile. Distinguishes between barriers addressable through design and those requiring specialist support.

Its SKILL.md is about 3.5k 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

  • “Use the udl-barrier-anticipator skill to predict access barriers in a learning task before delivery, given a learner variability profile”
  • “/udl-barrier-anticipator”

Workflow steps

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

  1. Identifying barriers but not distinguishing severity. Not all barriers are equally urgent. A barrier that prevents task completion is…
  2. Missing environmental and assessment barriers. Instructional UDL analysis focuses on the learning activity; environmental and assessment…
  3. Implying UDL can address all identified barriers. For students with complex or unidentified needs, UDL is the floor. Specialist referral…

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 Barrier Anticipator loads about 3.5k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 729 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
~3.5k

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 729 words (~3,517 tokens).

“Given a task description and a learner variability profile, predicts likely access barriers before the lesson runs and suggests proactive design changes. This is the preventive design skill — it moves UDL from reactive adaptation (modifying after a student fails)…”
