What it does

Text Complexity Analyser is an agent skill from GarethManning/education-agent-skills. Analyse text complexity across quantitative, qualitative, and reader-task dimensions with scaffolding recommendations. Use when selecting texts, assessing readability, or planning reading support.

Its SKILL.md is about 5.7k 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 Development, covering Project scaffolding and Plain language and style rules. 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

  • Selecting texts
  • Assessing readability
  • Planning reading support

Example prompts

  • “/text-complexity-analyser”

Workflow steps

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

  1. Pair discussion (3 minutes): "Compare annotations with your partner. What did the soldier REALLY mean? Find the biggest gap between what…
  2. Whole-class discussion (4 minutes): "What can this letter tell us about trench conditions — and what CAN'T it tell us? Why is this source…

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

Text Complexity Analyser loads about 5.7k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 1,908 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
~5.7k

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 1,908 words (~5,710 tokens).

“Evaluates a text across three dimensions of complexity — quantitative (sentence length, vocabulary frequency), qualitative (structure, levels of meaning, knowledge demands), and reader-task (the interaction between the text's demands and the specific readers and purpose) — and generates a tailored…”
