Hedron: Skill for Claude Code

.claude/skills/implement-plan/SKILL.md

implement-plan is a skill for Claude Code from dmbyer/Hedron. It costs 86 tokens per session (1,465 once invoked), scanned A, original, no licence file.

An implementation helper for building a complete gameplay use case from a plan, such as buying an item, fighting, or crafting. It maps the work to the game components, systems, handlers, and events involved.

In plain words
What is it for?
Use it to implement an end-to-end gameplay flow and sequence the work so each part can be tested on its own.
Why use it?
Large gameplay features often cross several parts of a game, making it easy to miss a connection or build pieces in the wrong order.

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

implement-plan 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 2mo 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.

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.
