kanban-lite: Instructions file for GitHub Copilot

.github/instructions/capability-provider.instructions.md

capability provider invariants is an instructions file for GitHub Copilot from borgius/kanban-lite. It costs 397 tokens per session, scanned A, original, MIT.

A set of rules for keeping capability providers and their configuration consistent in a software system. It covers actor-specific card state, callback runtimes, plugin provider selection, display titles, and same-provider attachment storage.

In plain words
What is it for?
Use it when changing card state, callback providers, Cloudflare callbacks, plugin settings, display-title helpers, plugin installation, or MySQL/PostgreSQL attachment storage.
Why use it?
It prevents user-specific data from leaking into shared content and stops the system from running with mismatched or unsafe providers. It also keeps configuration and runtime behavior aligned.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is borgius/kanban-lite's own configuration. It tells GitHub Copilot how to work on kanban-lite 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 kanban-lite 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

capability provider invariants 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 it actually says

Capability / provider invariants

  • card.state and callback.runtime are first-class capability/provider namespaces.
  • Actor-scoped card state must live outside shared card content/frontmatter.
  • Standalone transports that expose card.state must decorate cards per request/session auth context; raw shared broadcasts must not carry actor-scoped state.
  • Board-configured card display titles must use the shared display-title helper; raw markdown title extraction remains the source of truth for storage, filenames, and rename logic.
  • Callback configuration lives in shared plugin settings; plugin enablement maps to plugins[capability].provider, not a separate enabled boolean.
  • Cloudflare callback.runtime uses plugins["callback.runtime"].provider === "cloudflare" with type: "module" handlers only.
  • Enabled Cloudflare callback module-set changes are bootstrap/redeploy gated and must fail closed on runtime drift.
  • Cloudflare queue delivery is event-scoped; durable checkpoints and idempotency are tracked per handler.
  • For MySQL/PostgreSQL same-provider attachment.storage, use createMysqlAttachmentPlugin(engine) / createPostgresqlAttachmentPlugin(engine) instead of placeholder exports.
  • In-product plugin installs accept only exact unscoped kl-* package names; reject scopes, specifiers, flags, URLs, paths, and extra args.
  • Plugin-settings reads, lists, errors, and install output must reuse the shared redaction policy across SDK, API, CLI, MCP, and UI surfaces.
  • JSON Forms provider-option UIs should reuse the shared .card-jsonforms wrapper/styling hook instead of introducing a second theme.

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.
