sideboard CLAUDE.md

sideboard CLAUDE.md is an instructions file for coding agents from mmyslin/sideboard. It costs 893 tokens per session, scanned A, original, MIT.

Project instructions for Sideboard, a tool that manages roadmaps through GitHub Issues, which are GitHub's trackable work items.

In plain words
What is it for?
Use them when creating, editing, closing, ordering, or sequencing Sideboard roadmap issues with the GitHub command-line tool.
Why use it?
They explain where roadmap data lives and prevent developers from treating the project like one that uses local roadmap files.

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

sideboard CLAUDE.md 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 3d 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 it actually says

Sideboard — working notes for Claude

Sideboard's own roadmap lives in GitHub Issues (mmyslin/sideboard). The project is GitHub-only — there is no roadmap.json / local-file mode.

  • Manage roadmap items via ghgh issue create / edit / close / reopen. Swimlane (backlog vs in_progress) + card order live in .sideboard/meta.json (committed sidecar); done = a closed issue; a card's #N is its GitHub issue number. The sidecar is reconciled automatically by the router from the issues + your drag/reorder — don't hand-edit it.
  • Sequences — ordered dependency chains of ≥2 issues (in .sideboard/meta.json), managed via the /sideboard:roadmap-sequence command + the router's /api/seq/*. Honor them when working: starting a sequenced issue with an unfinished predecessor → check in first; closing one → suggest the next. See skills/sideboard/SKILL.md → "Acting on a sequenced issue".
  • Repo layout is the plugin layout (#12): commands/ (the sideboard: slash commands), skills/sideboard/SKILL.md, scripts/ (router + shell scripts), hooks/hooks.json, and .claude-plugin/{plugin,marketplace}.json. install.sh is the legacy installer; it copies out of skills/+scripts/.
  • Releasing (version-bump convention): once listed in the community marketplace, Anthropic's CI auto-advances the catalog's commit-SHA pin on every push — but users only receive an update when version in .claude-plugin/plugin.json changes. So push freely (docs, refactors, WIP); bump version (semver) only when you want users to get the change — that bump is the deliberate "ship it" lever. Keep the marketplace entry free of a version field so plugin.json stays the single source of truth. No re-submission is needed for updates (whether each push is re-screened is undocumented).
  • Run the board: scripts/sideboard-up.sh — starts the router (scripts/sideboard_router.py) on :7777, which follows the active project and serves its board. Then open the pane once per project (or use /sideboard:roadmap). Under the plugin the SessionStart hook launches it for you.
  • Multi-project / auto-follow (#35): one router serves ALL projects. A global Claude Code hook (scripts/sideboard-active.sh, on SessionStart + UserPromptSubmit) POSTs the session TITLE to the router, which maps title→project dir (~/.claude/sideboard-projects.json, token-matched, editable) and switches the served board. cwd is useless here (always $HOME) — title is the only signal. The preview pane is per-session, so open it once per project with /sideboard:roadmap; thereafter switching projects (send a message) makes each project's pane show its own roadmap.
  • Discovery keys off .sideboard/meta.json: a project is only picked up once that sidecar exists. Bootstrap a new repo with mkdir -p .sideboard && printf '{"schema": 2}\n' > .sideboard/meta.json (commit it); the router reconciles it from the issues on first sync.
  • Design + phases: docs/github-sync-design.md (#15). Distribution: shipped as a Claude Code plugin (#12) — community-marketplace submission is the remaining discoverability step. Naming decision: #39.

The global sideboard skill (skills/sideboard/SKILL.md) documents this same GitHub-only model — this file is just the repo-specific pointer.

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.
