What it does
Do Not Repeat Yourself is an agent skill from Dimon94/skills. Find and reuse the nearest correct mechanism before adding another. Use when a change would add reusable code, policy, or workflow meaning.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development. The repository describes itself as: 个人 agent skill 库 — skills/ 为唯一真相源，agent 目录经 symlink 消费.
When your agent uses it
- A change would add reusable code
- Workflow meaning
Example prompts
- “/do-not-repeat-yourself”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Freeze the exact mechanism or staged diff in scope.
- Search nearby callers and same-directory patterns.
- Search repository utilities, scripts, Skills, docs, ADRs, and declared
- Prefer the language standard library, native platform, and installed
- Add a mechanism only when the earlier wheel is missing, wrong, or more costly
What it can do on your machine
Read from SKILL.md and the folder at commit 2531bc3. 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
Do Not Repeat Yourself loads about 551 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 281 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 281 words (~551 tokens).
“Run this gate before adding a helper, utility, adapter, validator, parser, script, schema, Skill, prompt rule, or any other reusable mechanism, and again before committing. DRY means do not duplicate meaning or wheels; it does not mean extracting every similar…”
