What it does
Cross Cultural Task Validity Checker is an agent skill from GarethManning/education-agent-skills. Check an educational practice or task for cultural bias, WEIRD assumptions, and cross-cultural validity. Use when adapting resources for diverse contexts or questioning universal claims.
Its SKILL.md is about 6.9k 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.
When your agent uses it
- Adapting resources for diverse contexts
- Questioning universal claims
Example prompts
- “/cross-cultural-task-validity-checker”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- This analysis identifies POSSIBLE cultural assumptions, not certainties. Not all students from collectivist cultures are uncomfortable…
- Cultural analysis risks stereotyping. Saying "South Asian students may be uncomfortable with peer discussion" is a generalisation that may…
- The teacher's own cultural assumptions are also at play. A teacher trained in Anglophone pedagogy may unconsciously interpret silence as…

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
Cross Cultural Task Validity Checker loads about 6.9k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 2,663 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 2,663 words (~6,947 tokens).
“Analyses an educational task, strategy, or research-based practice for hidden cultural assumptions that may limit its validity or effectiveness when used with students from different cultural backgrounds. The critical insight from Henrich, Heine & Norenzayan (2010) is that most educational…”
