What it does
Fskill Creator Migrate is an agent skill from AGI-comming/functional-skill-creator. Migrate lane for fskill-creator; analyzes a legacy skill directory into behavior map, function split proposal, and source evidence.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including scripts and reference files (for example `functions/extract_shared_references.md`, `functions/load_legacy_skill.md` and `functions/map_existing_behavior.md`).
It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: fskill-creator turns your long-text SKILL into functions, making it modular, testable and trackable for better long-term maintenance and iteration. The licence is MIT.
When your agent uses it
- Tasks that involve Skill authoring
Example prompts
- “/fskill-creator-migrate”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 38509bb. 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
Ships 5 files in scripts/ (JavaScript), which the agent can run.
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
Fskill Creator Migrate loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 438 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); the scripts in this folder are not scanned.

fskill-creator-migrate
Goal
Analyze a large or hard-to-maintain legacy skill directory into structured migration context while preserving behavior. This sub-skill only performs migration pre-analysis and does not directly write final functional skill files; final artifact generation, runtime capability provisioning, file writing, and validation are handled by the main fskill-creator.
Invoked by the main skill when the user has an existing monolithic skill and wants to "refactor into functional", "migrate to functional skill", or "restructure into functions/references/scripts".
Principles
- Preserve existing behavior first, then optimize structure.
- Load the whole legacy skill package, not only
SKILL.md. - Keep source section and file evidence so reviewers can trace migrated content.
- Only output
migration_context; must not directly write target skill files. - Duplicated rules, schemas, and vocabulary move to
reference_plan. - Existing
references/,scripts/, andtools/are inventoried before proposing splits. - Deterministic parsing, formatting, validation, or mechanical transforms are identified as
script_plan, to be generated or preserved later by the main skill. - Optional viewers only enter
tool_plan; final files are generated uniformly by the main skill'sadd_runtime_capabilities.
