What it does

Cognition Router is an agent skill from hashgraph-online/awesome-codex-plugins. Use this skill whenever a design task involves cognition, mental models, learnability, complexity reduction, defaults, memory, scanning, or comprehension — regardless of framework or platform. Trigger when the user is designing forms, settings, onboarding, dashboards with many widgets, complex tables, navigation IA, search experiences, or any flow that has many options or asks the user to learn something new. Trigger when the user mentions "too complex," "too many options," "users keep getting confused,"…

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/further-reading.md`).

The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • A design task involves cognition
  • Complexity reduction
  • Comprehension — regardless of framework
  • The user is designing forms

Example prompts

  • “too complex,”
  • “too many options,”
  • “users keep getting confused,”
  • “/cognition-router”

What it can do on your machine

Read from SKILL.md and the folder at commit 3e1456a. 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

Cognition Router loads about 1.5k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 171 tokens; SKILL.md has 523 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~171
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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.

description
Use this skill whenever a design task involves cognition, mental models, learnability, complexity reduction, defaults, memory, scanning, or comprehension — regardless of framework or platform. Trigger when the user is designing forms, settings, onboarding, dashboards with many widgets, complex tables, navigation IA, search experiences, or any flow that has many options or asks the user to learn something new. Trigger when the user mentions "too complex," "too many options," "users keep getting confused," defaults, labels, copy, mental models, progressive disclosure, autocomplete, or ergonomics. Routes the model to the right cognition principle in this plugin.

Cognition & learnability — router

This plugin holds the principles that govern how easily a user can understand, learn, and remember an interface. They are framework-agnostic and apply equally to web apps, mobile apps, desktop software, control panels, in-car displays, and printed forms.

Principles in this plugin

Each principle has its own skill (with sub-aspect skills where useful). Principles marked [full] have reference-grade skill files; the rest are planned and will be added in subsequent passes.

Complexity reduction
  • hicks-law [full] — decision time grows with the log of the number of options.
    • Sub-skills: hicks-law-menus, hicks-law-defaults, hicks-law-pricing.
  • 80-20-rule — 80% of usage flows through 20% of features; design the default for the 80%.
  • chunking — group items into ~4±1 chunks so working memory can hold them.
  • performance-load — total cognitive + kinesthetic effort to do a task; minimize both.
  • progressive-disclosure — show only what's needed now; reveal advanced controls on demand.
  • satisficing — users pick the first acceptable option, not the optimal one.
  • ockhams-razor — among solutions that work, prefer the simplest.
Mental models and recognition
  • mental-model — users come with a model of how the system works; design to match it.
  • recognition-over-recall — recognizing is easier than remembering; show options.
  • visibility — features that aren't visible aren't used.
  • mapping — controls map onto what they affect.
  • constancy — visual properties remain stable across state changes.
  • iconic-representation — pictures are recognized faster than words but only when conventional.
  • mimicry — borrow successful familiar patterns rather than invent.
  • rosetta-stone — pair a known referent with a novel concept.
Chunking, scanning, and memory
  • inverted-pyramid — most important info first, then supporting detail.
  • five-hat-racks — five ways to organize: Location, Alphabet, Time, Category, Hierarchy.
  • advance-organizer — a structural preview before content (TOC, breadcrumbs).
  • serial-position-effects — first and last items are remembered best.
  • stickiness — memorable, concrete content earns repeat use.
  • storytelling — narrative encodes meaning more memorably than bullets.
  • picture-superiority-effect — images outlast text in memory.
  • mnemonic-device — explicit memory aids reduce recall cost.
  • propositional-density — meaning per visible mark; high density reads as polished.
Show full SKILL.md (209 more words)Show less
Wayfinding and navigation
  • wayfinding [full] — orienting, choosing routes, monitoring progress, recognizing destinations.
    • Sub-skills: wayfinding-physical-spatial-metaphors, wayfinding-search-and-recovery, wayfinding-breadcrumbs-and-context.
  • progressive-disclosure [full] — show what's needed now; tuck the rest behind explicit affordances.
    • Sub-skills: progressive-disclosure-defaults-and-tucking, progressive-disclosure-disclosure-affordances.
Consistency and encoding
  • consistency — same things look and behave the same.
  • cognitive-dissonance — contradictions between expectation and behavior cost trust.
  • confirmation-bias — users notice what confirms their model and ignore what doesn't.
  • comparison — comparison is easier than evaluation.
  • depth-of-processing — interactive engagement yields better memory than passive reading.
  • priming — exposure shapes how a subsequent stimulus is processed.
  • framing — how information is framed changes the choice users make.
  • modularity — break complex systems into independent, recombinable units.
  • redundancy — multiple independent signals make critical info reliable.

Heuristic for which to read first

  • Designing a long form or settings page → chunking, progressive-disclosure, hicks-law, mental-model.
  • Picking defaults → satisficing, 80-20-rule, hicks-law-defaults, framing.
  • Picking an icon set → iconic-representation, recognition-over-recall, mimicry.
  • Designing a dashboard → propositional-density, chunking, inverted-pyramid.
  • Onboarding → mental-model, advance-organizer, depth-of-processing, storytelling.
  • Search / navigation IA → wayfinding, recognition-over-recall, five-hat-racks, visibility.
  • "Users keep getting lost" → wayfinding, wayfinding-breadcrumbs-and-context, wayfinding-search-and-recovery.
  • Settings / forms feel overwhelming → progressive-disclosure, chunking, hicks-law.
  • Reviewing a confusing flow → mental-model, cognitive-dissonance, consistency.
