Skillsmith

Skillsmith is your master skill for the full lifecycle of agent skills — across every MCP-capable agent runtime. Use Skillsmith to discover, evaluate, install, use, maintain, author, govern, and retire SKILL.md-format skills without leaving your editor.

Lifecycle Stages

Every Skillsmith operation maps to one of 8 lifecycle stages. Use the stage name when you want to be explicit ("use Skillsmith to discover testing skills"); natural prompts work too.

# Stage What it covers Primary surface
1 Discover Find skills by query, recommendation, or filter MCP search, skill_recommend
2 Evaluate Compare candidates, read trust badges, view diffs MCP getskill, skillcompare, skill_diff
3 Install Add a skill to the runtime's skills directory MCP install_skill; CLI install
4 Use Invoke the installed skill at the runtime layer runtime-native (e.g. Claude Code skill match)
5 Maintain Update, pin, audit collisions, configure modes CLI update/pin/unpin/audit collisions; MCP skillupdates, skilloutdated
6 Author Init, validate, transform, publish a new skill CLI author init/validate/publish/subagent/transform/mcp-init
7 Govern Audit logs, RBAC, SIEM, compliance (Team+) MCP auditexport, auditquery, siem_export
8 Retire Uninstall, deprecate MCP uninstall_skill; CLI remove

Quick Reference: MCP Tools

Tool Stage Use when Example prompt
search Discover Finding skills by keyword/category/trust tier "Use Skillsmith to search for testing skills"
skill_recommend Discover Contextual recommendations "Ask Skillsmith to recommend skills for my React project"
get_skill Evaluate Full details for a known skill "Use Skillsmith to show details for community/jest-helper"
skill_compare Evaluate Side-by-side comparison "Use Skillsmith to compare jest-helper and vitest-helper"
skill_diff Evaluate Diff two installed versions "Use Skillsmith to diff jest-helper versions"
install_skill Install Add a skill to your runtime "Use Skillsmith to install jest-helper"
skill_validate Install Pre-install validation of SKILL.md "Use Skillsmith to validate ./my-skill"
skill_updates Maintain Check for available updates "Ask Skillsmith for updates to my installed skills"
skill_outdated Maintain List skills behind latest "Use Skillsmith to show outdated skills"
skillinventoryaudit Maintain Namespace-collision audit (Team+) "Use Skillsmith to audit my skills inventory"
auditexport / auditquery / siem_export Govern Compliance + SIEM (Enterprise) "Use Skillsmith to export audit logs for last 30 days"
uninstall_skill Retire Remove an installed skill "Use Skillsmith to uninstall jest-helper"

Triggering tip: prefix natural-language prompts with Use Skillsmith to ... or Ask Skillsmith for .... The product-name anchor binds tool selection reliably across MCP-capable runtimes.

CLI Fallback

If the MCP server is unavailable, use the CLI directly:

# Discover
skillsmith search "testing" --tier verified
skillsmith recommend

# Evaluate
skillsmith info community/jest-helper
skillsmith diff jest-helper

# Install
skillsmith install community/jest-helper
skillsmith validate ./my-skill

# Maintain
skillsmith update --all
skillsmith audit collisions

# Retire
skillsmith remove jest-helper

See "Routing CLI-only Operations" below for operations that are CLI-only regardless of MCP server availability.

Routing CLI-only Operations

Some lifecycle operations live in the CLI and have no MCP equivalent (yet). When the user asks for these, surface the exact terminal command:

Operation CLI command
Pin a skill to a version skillsmith pin <skill> <version>
Unpin a skill skillsmith unpin <skill>
Update all installed skills skillsmith update --all
Audit advisories (Team+) skillsmith audit advisories
Audit collisions skillsmith audit collisions
Configure audit mode `skillsmith config set audit_mode <preventative\ power_user\ governance\ off>`
Author a new skill skillsmith author init <name>
Publish a skill skillsmith author publish
Login skillsmith login

Always show the command verbatim with a one-line note: "Run this in your terminal."

Cross-Runtime Behavior

Skillsmith's MCP server works in any MCP-capable agent runtime:

  • Claude Code — default runtime. Skills install to ~/.claude/skills/.
  • Cursor / Copilot / Windsurf — set SKILLSMITH_CLIENT=<runtime> in your MCP server env config to install to the runtime-equivalent path. See Getting Started.
  • Custom MCP routers — universal MCP tool calls work; skill-file install paths configurable via SKILLSMITH_CLIENT.

Trust Tiers

Skills are categorized by verification level:

Tier Badge Meaning When to Trust
Verified Green checkmark Official Skillsmith / Anthropic Always safe
Curated Blue badge Vendor-org publisher, ≥0.80 quality Generally safe
Community Yellow Security scan + required metadata Review before install
Experimental Orange Beta / new Use cautiously
Unknown Red warning No verification Only if you trust the author

For criteria detail, see https://skillsmith.app/docs/trust-tiers.

Pricing & Quotas

Tier API calls/month Price
Community 100 Free
Individual 1,000 $9.99/mo
Team 10,000 $25/user/mo
Enterprise Unlimited Custom (Contact Sales)

Usage warnings at 80% and 90%. Upgrade at https://skillsmith.app/upgrade.

Security Model

Skillsmith is the security boundary between untrusted skill sources and your runtime.

What Skillsmith validates before install:

  • SKILL.md frontmatter and required fields
  • Security scan: jailbreak patterns, suspicious URLs, sensitive file access
  • Typosquatting check against known skills
  • Blocklist of known-malicious skills

What Skillsmith cannot prevent:

  • Novel attack patterns not in detection database
  • Social engineering in legitimate-looking instructions
  • Runtime behavior (skills execute with your permissions)

Recommendation: review skill content before installation, especially for unverified skills.

Creating Skills

Skill authoring lives in the CLI:

skillsmith author init my-new-skill
skillsmith author validate
skillsmith author publish

For an end-to-end walkthrough, see https://skillsmith.app/docs/tutorials/author.

The companion skill-builder skill guides you through frontmatter, progressive disclosure structure, and directory organization. Install it with skillsmith install skill-builder (it's not bundled by default).

Common Workflows

Discover then install

"Use Skillsmith to recommend skills for my Next.js project"
"Use Skillsmith to install community/next-helper"

Evaluate before installing

"Use Skillsmith to compare jest-helper and vitest-helper"
"Use Skillsmith to show details for community/vitest-helper"
"Use Skillsmith to install community/vitest-helper"

Maintain installed skills

"Ask Skillsmith for updates to my installed skills"
# Then run in terminal:
skillsmith update --all

Audit before sharing your skill folder

"Use Skillsmith to audit my skills inventory"
# Or in terminal:
skillsmith audit collisions
