set-core: Skill for Claude Code

.claude/skills/set/wave-board/SKILL.md

set:wave-board is a skill for Claude Code from tatargabor/set-core. It costs 129 tokens per session (1,705 once invoked), scanned A, original, MIT.

A live status board for a multi-step job whose work is divided into waves. It records which items are complete, active, or blocked in a repository file and a private page.

In plain words
What is it for?
Use it for long cleanups, migrations, or other jobs with several steps that must continue across sessions or be handed between people.
Why use it?
Ordinary task lists can lose their state when work spans sessions, projects, machines, or people. This board keeps progress tied to evidence and updates status automatically when work stops.

This is tatargabor/set-core's own configuration. It tells Claude Code how to work on set-core itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything set-core configures →

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

set:wave-board 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Wave board — set-wave-board

A process roadmap, not a product roadmap: which wave a job is in, which item is done, in progress or blocked, and what is left. One job is one tracked file, docs/waveboard/<job>.json, in the repository that runs the job, and one private Artifact page that shows it live.

When to use it

Use a board when a job has several steps that outlive one session or run across several projects: the status must survive a compact, a /clear, a second machine and a second person. A three-step task done in one sitting does not need one; a todo list is enough there.

How the status stays true — three layers

  1. The job file — waves, items, and for each item the evidence that proves it.
  2. sync, run by the set-hook-waveboard Stop hook on every stop, whether or not you remembered — it derives status from evidence.
  3. Your own report, set-wave-board set <job> <item> <status> — the fast lane. Report every finished step with it, straight away. But evidence and the hook are the guarantee: where evidence speaks it overrides your report (a done with unchecked task boxes comes back as doing, and set says so). Only blocked and skipped survive evidence — they are human decisions.

Give every item evidence wherever one exists. An item without evidence is only as reliable as the last report.

Evidence Done when
{"type":"openspec-tasks","path":"openspec/changes/<x>/tasks.md"} every box checked (some = doing, none = todo); also when only openspec/changes/archive/*-<x>/tasks.md exists
{"type":"path-exists","path":"<repo-relative path>"} the path exists
{"type":"commit","grep":"<pattern>"} git log --grep on HEAD finds a commit
{"type":"project","project":"<registry name>","evidence":{...}} the nested evidence holds in that registered project

Paths are relative to the repository root — never absolute; another project is named by its set-core registry name and resolved per machine. A missing path or commit is not a verdict: the status stays as it was (absence cannot tell "not yet" from "not on this machine"). A project not registered on this machine is reported as UNRESOLVED and left alone.

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.
