skillify

skillify is a skill for Claude Code, Codex from fmind/dot. It costs 38 tokens per session (819 once invoked), scanned A, original, MIT.

A workflow for turning a conversation or repeated development process into a reusable instruction file called a skill.

In plain words
What is it for?
Use it to create or update local or global skills from a learned process, including the commands, triggers, scope, and validation steps.
Why use it?
It preserves useful decisions, commands, and lessons so another coding session can repeat the workflow without the original conversation.

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.

Security

Grade A, and why

skillify 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 yesterday.

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.

Skillify

Capture what this session learned as a skill the next session can run without the conversation. The agent-skills skill owns the package format and validation; this skill owns the extraction and the writing.

Workflow

  1. Extract from the session: the goal, the user's trigger phrases, the exact commands that worked (with flags), the decisions and why, the dead ends, and the tools required; drop session-specific paths, one-off values, and secrets.
  2. Check the catalog: skills list and skills list -g, then read any neighbor with an overlapping description; extend it when the workflow is the same, write a new skill only for a distinct trigger, and link neighbors instead of copying them.
  3. Choose the scope:
    • Global (reusable, tool-generic): ~/.agents/skills/<name>/, the skills/ directory of the dot repository; add its CLI names to skills/contracts.json, then run mise run check:skills and mise run test there.
    • Local (repository-specific commands, data, or conventions): .agents/skills/<name>/ in the project; add .claude/skills -> ../.agents/skills if missing per agent-project.
  4. Write from the template: copy skill.md and apply the Skill Authoring Limits of the global ~/.agents/AGENTS.md for name, description, size, shape, and placement; long configs and examples go to references/.
  5. Validate: frontmatter name equals the directory; every link resolves; every required tool is named in the body; gh skill publish --dry-run <parent-dir> passes for a global skill.
  6. Test once: run the skill's steps in a scratch directory or on the current repository and fix what does not reproduce; a skill that was never executed is a draft.
  7. Report: the path, the description, the scope, and whether the routing probes in dot/testdata/skills/ need a new prompt for the skill.

Extracting from AGENTS.md

When AGENTS.md grows past rules and layout, move each multi-step section into its own local skill, leave a one-line pointer ("see .agents/skills/<name>"), and re-run readme-agents.

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.

skillify is a skill published in the GitHub repository fmind/dot (4 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 819 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
