What it does
Skill Forge is an agent skill from AgriciDaniel/skill-forge. Ultimate Claude Code skill creator and architect. Designs, scaffolds, builds, reviews, evolves, and publishes production-grade Claude Code skills following the Agent Skills open standard and 3-layer architecture (directive, orchestration, execution). Handles single-file skills, multi-skill orchestrators with sub-skills and subagents, MCP-enhanced workflows, and full skill ecosystems. Industry detection for skill domain. Triggers on: "create skill", "build skill", "new skill", "skill creator", "skill builder"…
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including scripts, reference files and assets (for example `assets/templates/ecosystem.md`, `assets/templates/minimal.md` and `assets/templates/multi-skill.md`).
It sits in Agent Workflows, covering Skill authoring, Project scaffolding and Agent evaluation and testing. It works with Model Context Protocol. The repository describes itself as: Ultimate Claude Code skill creator — design, scaffold, build, review, evolve, and publish production-grade AI agent skills. The licence is MIT.
When your agent uses it
- Skill architecture
- Benchmark skill
- Skill performance
Example prompts
- “create skill”
- “build skill”
- “new skill”
- “/skill-forge”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash, Write, Edit, WebFetch
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 2872ee9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBashWriteEditWebFetch
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python
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
Skill Forge loads about 1.9k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 208 tokens; SKILL.md has 729 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Grep, Glob, Bash, Write, Edit, WebFetch
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); the scripts in this folder are not scanned.

Orchestration Logic
Interactive Mode (/skill-forge)
Walk the user through the full skill creation lifecycle:
- Discovery: Ask about the domain, use cases, and target users
- Architecture: Determine skill complexity tier and design structure
- Build: Generate all files following chosen template
- Review: Validate structure, frontmatter, triggers, and quality
- Eval: Run eval pipeline with assertions and grading
- Benchmark: Measure pass rate, time, tokens with variance analysis
- Iterate: Refine based on eval results and feedback
Command Routing
For specific commands, load the relevant sub-skill:
/skill-forge plan->skills/skill-forge-plan/SKILL.md/skill-forge build->skills/skill-forge-build/SKILL.md/skill-forge review->skills/skill-forge-review/SKILL.md/skill-forge evolve->skills/skill-forge-evolve/SKILL.md/skill-forge eval->skills/skill-forge-eval/SKILL.md/skill-forge benchmark->skills/skill-forge-benchmark/SKILL.md/skill-forge publish->skills/skill-forge-publish/SKILL.md/skill-forge convert->skills/skill-forge-convert/SKILL.md
Skill Complexity Tiers
Detect the appropriate tier based on user's description:
Tier 1: Single Skill (1 SKILL.md)
- Simple workflow or document generation
- No sub-skills or subagents needed
- Under 200 lines of instructions
- Template:
assets/templates/minimal.md
Tier 2: Skill + Scripts (SKILL.md + scripts/)
- Needs deterministic execution (validation, data processing)
- Python/Bash scripts for fragile operations
- Template:
assets/templates/workflow.md
Tier 3: Multi-Skill Orchestrator (main + sub-skills)
- Complex domain with multiple distinct workflows
- Main skill routes to specialized sub-skills
- Shared references across sub-skills
- Template:
assets/templates/multi-skill.md
Tier 4: Full Ecosystem (orchestrator + sub-skills + agents + scripts)
- Enterprise-grade skill with parallel subagent delegation
- Multiple execution scripts for deterministic tasks
- Industry templates and reference knowledge
- Template:
assets/templates/ecosystem.md
Core Principles (Enforce in ALL generated skills)
1. Progressive Disclosure (3 Levels)
- Level 1 (frontmatter): Always in system prompt. Name + description only (~50-100 tokens)
- Level 2 (SKILL.md body): Loaded on activation. Core instructions (<500 lines, <5000 tokens)
- Level 3 (references/scripts/assets): Loaded on-demand. Detailed knowledge and execution
2. Description is King
The description field determines when the skill activates. It MUST contain:
- WHAT the skill does (capabilities)
- WHEN to use it (trigger phrases users would say)
- Key domain keywords for matching
Read references/description-guide.md for the complete framework.
3. The 3-Layer Architecture
- Layer 1 (Directive): SKILL.md instructions, reference files = the "what"
- Layer 2 (Orchestration): Claude's routing and decision-making = the "how"
- Layer 3 (Execution): Scripts in scripts/ = the "do"
Push deterministic work into scripts. Keep probabilistic decisions in instructions.
Show full SKILL.md (279 more words)Show less
4. Naming Conventions
- Skill folder:
kebab-case(lowercase + hyphens only) - Name field must match folder name exactly
- Sub-skills:
{parent}-{child}(e.g.,seo-audit,ads-google) - Agents:
agents/{skill}-{role}.md(e.g.,agents/seo-technical.md) - No "claude" or "anthropic" in skill names (reserved)
5. File Rules
- Required:
SKILL.md(exact case) - No
README.mdinside skill folders - No XML angle brackets in frontmatter
- Reference files: focused, small, loaded on-demand
- Scripts: atomic, testable, well-documented
Quality Gates
Before marking any generated skill as complete:
- SKILL.md exists with valid YAML frontmatter
- Name is valid kebab-case (1-64 chars)
- Description includes WHAT + WHEN + keywords (<1024 chars)
- No XML tags in frontmatter
- Instructions are specific and actionable (not vague)
- Error handling included for common failures
- Examples provided for key workflows
- SKILL.md body under 500 lines
- Reference files linked (not inlined) for detailed knowledge
- Scripts have docstrings, type hints, error handling
Run python scripts/validate_skill.py <path> to verify programmatically.

With the skills CLI, run `npx skills add AgriciDaniel/skill-forge --skill skill-forge -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skill-forge, .gemini/skills/skill-forge, .github/skills/skill-forge and .opencode/skills/skill-forge in your project.
What does Skill Forge need to run?
Going by SKILL.md and its folder, Skill Forge needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Grep, Glob, Bash, Write, Edit, WebFetch.
Does Skill Forge 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 Skill Forge safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Skill Forge use?
Skill Forge is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Skill Forge use?
About 1.9k tokens (SKILL.md is roughly 7.8k 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 12k tokens, read only when the agent opens those files.
