What it does

Solid is an agent skill from ramziddin/solid-skills. Use this skill when writing code, implementing features, refactoring, planning architecture, designing systems, reviewing code, or debugging. This skill transforms junior-level code into senior-engineer quality software through SOLID principles, TDD, clean code practices, and professional software design.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/architecture.md`, `references/clean-code.md` and `references/code-smells.md`).

It sits in Development, covering Design patterns, Test-driven development and Refactoring. The repository describes itself as: AI agent skill for writing senior-engineer quality code through SOLID principles, TDD, and clean architecture.

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 94978c9. 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 (its code samples are typescript).
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

Solid loads about 2.7k tokens when it runs, and up to ~23k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 1,155 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~78
When it runs · the whole SKILL.md, loaded when a task matches: ~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~23k

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 1,155 words (~2,660 tokens).

“You are now operating as a senior software engineer. Every line of code you write, every design decision you make, and every refactoring you perform must embody professional craftsmanship.”

Solid is an agent skill from ramziddin/solid-skills. Use this skill when writing code, implementing features, refactoring, planning architecture, designing systems, reviewing code, or debugging.

When should I use Solid?

Solid fits situations like: implementing features; planning architecture; designing systems.

How do I install Solid in Claude Code?

Run `npx skills add ramziddin/solid-skills --skill solid -a claude-code`. Or copy the skill folder (skills/solid in ramziddin/solid-skills) into .claude/skills/solid in your project. Claude Code loads it when a task matches its description.

How do I install Solid in Codex?

Run `npx skills add ramziddin/solid-skills --skill solid -a codex`. Or copy the skill folder (skills/solid in ramziddin/solid-skills) into .agents/skills/solid in your project. Codex loads it when a task matches its description.

Can I use Solid in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ramziddin/solid-skills --skill solid -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/solid, .gemini/skills/solid, .github/skills/solid and .opencode/skills/solid in your project.

What does Solid need to run?

SKILL.md names no scripts, command-line tools or credentials: Solid is instructions for the agent only.

Does Solid access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Solid safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Solid use?

No licence was found for Solid or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Solid use?

About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 20k tokens, read only when the agent opens those files.

What are the alternatives to Solid?

Skills that share tags, products or a category with Solid: Go Rig (mudrii/openclaw-dashboard, 457 stars), Go Rig (mudrii/openclaw-dashboard, 457 stars), Py Rig (mudrii/hermesd, 119 stars) and Omni Dev (GulajavaMinistudio/Mayukai-Theme, 139 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Solid?

ramziddin (a GitHub user) maintains it in ramziddin/solid-skills, which has 606 GitHub stars. The repository was last updated on September 3, 2026.

Source: ramziddin/solid-skills on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
