basic-functional-skill

A starter template for defining a functional agent skill. It provides placeholders for the workflow, inputs, outputs, shared terms, helper functions, and files the skill may change.

In plain words
What is it for?
Use it as a starting point when designing a new agent skill and documenting its functions, references, inputs, outputs, and scope.
Why use it?
It gives an unfinished skill a consistent structure, but the supplied material does not describe a completed capability.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code, Codex.

Per session 13 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 234 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

basic-functional-skill 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.

What it actually says

basic-functional-skill

Goal

Describe the workflow this skill is responsible for.

Principles

  • SKILL.md only handles orchestration.
  • functions/*.md defines local function contracts.
  • references/*.md defines shared rules and terminology.
  • scripts/*.mjs carries deterministic helper logic.
  • Tests and traces support controllable iteration.

References

Resource Load Timing Purpose
shared_glossary On demand Shared terminology and stable field semantics.

External Inputs

Field Source Description
input user Replace with concrete workflow input.

Execution Pipeline

Step Function Purpose Input Output
1 example_function Replace with a real function. input output

Output Scope

Describe what files, data, or artifacts this skill may create or modify.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

basic-functional-skill is a skill published in the GitHub repository AGI-comming/functional-skill-creator (359 stars, last pushed 2mo ago), licensed MIT. It adds 13 tokens to every session and 234 once invoked, about $0.0001 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 2026-08-30.
