What is migrate-skills-between-libraries?

Instructions for moving coding-agent skills from one library workspace to another. The process checks the source, avoids name collisions, previews changes, and rebuilds documentation afterward.

Use it to transfer selected skills between personal and team libraries, including exporting source details, importing copies, and validating the target library.

It helps prevent duplicate skills, missing metadata, and broken library documentation during a migration. A dry run lets you inspect the proposed changes before importing anything.

About the project

AI Agent Skills is a curated library and package manager for installing, organizing, and creating skills for compatible AI coding agents. It is for developers who want to manage reusable agent instructions through a command-line or terminal interface. The catalogue skills and agents are examples of the kind of add-ons it helps manage.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 19
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.00617
Opus 5.5	$0.00014	$0.00247
Sonnet 5.5	$0.00007	$0.00123
Haiku 4.5	$0.00004	$0.00062

Security

Grade A, and why

migrate-skills-between-libraries scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Migrate Skills Between Libraries

Goal

Move skills from one library workspace to another without losing metadata, breaking dependencies, or duplicating entries.

Guardrails

Always use --dry-run before any mutating command in the target workspace.
Always use --list to inspect the source library before importing.
Always use --format json for structured output when scripting migrations.
Never import skills without checking for name collisions in the target workspace first.
Always run build-docs in the target workspace after migration.

Workflow

Export: Identify skills to migrate from the source library

List all skills in the source workspace.

cd /path/to/source-library
npx ai-agent-skills list --format json --fields name,tier,workArea,collections

For house copies, note the skill folder paths. For upstream picks, note the installSource.

Import: Add skills to the target workspace

For house copies, use vendor to copy the skill folder into the target:

cd /path/to/target-library
npx ai-agent-skills vendor /path/to/source-library --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library." --dry-run
npx ai-agent-skills vendor /path/to/source-library --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library."

For upstream picks, use catalog to re-catalog from the original source:

npx ai-agent-skills catalog <owner>/<repo> --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library." --dry-run
npx ai-agent-skills catalog <owner>/<repo> --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library."

Rebuild docs in the target workspace.

npx ai-agent-skills build-docs

Validate the target workspace.

npx ai-agent-skills validate

Gotchas

Skill names must be unique per workspace. Check for collisions before importing.
House copies are full folder copies — the source and target are independent after migration.
Upstream picks re-catalog from the original upstream source, not the intermediate library.
Dependencies (requires field) must also be migrated. Check info --format json for each skill's dependency graph.
Collection membership does not transfer automatically. Use curate --collection <id> to add migrated skills to target collections.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migrate-skills-between-libraries is a skill published in the GitHub repository MoizIbnYousaf/Ai-Agent-Skills (1,152 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 617 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
