What it does
Abstraction Concrete Examples is an agent skill from lyndonkl/claude. Builds structured abstraction ladders that translate high-level principles into concrete, actionable examples across 3-5 levels. Bridges communication gaps, reveals hidden assumptions, and tests whether abstract ideas work in practice. Use when explaining concepts at different expertise levels, moving between abstract principles and concrete implementation, identifying edge cases by testing ideas against scenarios, designing layered documentation, decomposing complex problems into actionable steps, or bridging…
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files (for example `resources/evaluators/rubric_abstraction_concrete_examples.json`, `resources/examples/api-design.md` and `resources/examples/hiring-process.md`).
It sits in AI & LLM Engineering. The repository describes itself as: Agents, skills and anything else to use with claude.
When your agent uses it
- Explaining concepts at different expertise levels
- Moving between abstract principles and concrete implementation
- Identifying edge cases by testing ideas against scenarios
- Designing layered documentation

What it can do on your machine
Read from SKILL.md and the folder at commit 4acc337. 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
Abstraction Concrete Examples loads about 1.1k tokens when it runs. Until then it costs about 143 tokens; SKILL.md has 417 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 417 words (~1,145 tokens).
“The ladder uses 3-5 levels connecting universal principles to concrete details. Example:”
