What it does
Discover Engineering is an agent skill from rand/cc-polymath. Automatically discover software engineering practice skills when working with code review, documentation, pair programming, production debugging, performance profiling, deployment strategies, or software engineering practices. Activates for engineering development tasks.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.
It sits in Development, covering Code review. The repository describes itself as: Claude Code skills and workflows, optimized for context-efficiency and skill quality. Skills ranging from cloud infrastructure to design to advanced maths. The licence is MIT.
When your agent uses it
- Tasks that involve Code review
Example prompts
- “/discover-engineering”
Requirements
- Compatibility (from SKILL.md): Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- code-review - PR reviews, feedback, automation
- code-quality - SOLID principles, metrics, code smells
- refactoring-patterns - Safe refactoring techniques
- test-driven-development - TDD, red-green-refactor
- domain-driven-design - DDD patterns, bounded contexts
- functional-programming - FP principles, immutability
- design-patterns - GoF patterns, when to use
- technical-debt - Identifying and managing debt
- pair-programming - Pairing techniques, mob programming
- continuous-integration - CI/CD pipelines, deployment
What it can do on your machine
Read from SKILL.md and the folder at commit baa2df1. 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.
Compatibility
Designed for Claude Code. Compatible with any agent supporting the Agent Skills format.
From compatibility in the SKILL.md frontmatter.
Context cost
Discover Engineering loads about 723 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 264 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.
