kanban core surface

A set of development rules for changing the Kanban Lite SDK and its API, command-line interface, or MCP tools. It defines the order of implementation, keeps user-facing behavior aligned, and treats source documentation as authoritative.

In plain words
What is it for?
Use it when adding or changing Kanban Lite features, routes, CLI commands, MCP tools, JSDoc, README content, or changelog entries.
Why use it?
It reduces differences between the SDK, API, CLI, and MCP tools. It also prevents generated documentation from becoming outdated and keeps release notes and user guidance in sync.

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.

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

kanban core surface 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

Kanban core surface changes

  • Implement shared behavior in the SDK first, then wire the API, CLI, and MCP surfaces in that order.
  • Keep API, CLI, and MCP behavior in feature parity for user-facing capabilities.
  • Update JSDoc when logic, parameters, return types, or behavior change; JSDoc is the source of truth for docs/sdk.md.
  • Never edit generated docs/api.md, docs/sdk.md, or docs/webhooks.md manually; update the source metadata or JSDoc and regenerate them.
  • For user-facing changes, update README.md and CHANGELOG.md in the same task.
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.
