ckan-mcp-server: Command for Claude Code

.opencode/command/openspec-proposal.md

openspec-proposal is a command for Claude Code, OpenCode from ondata/ckan-mcp-server. It costs 11 tokens per session (570 once invoked), scanned A, a copy of OpenSpec: Proposal, MIT.

A change-proposal scaffold for OpenSpec, a system that records software changes as design documents before implementation. It creates the proposal files and checks them against the project's rules.

In plain words
What is it for?
Use it to inspect a repository, identify open questions, and create a proposal, design, and ordered task list for a planned change.
Why use it?
It keeps planning separate from coding, so unclear requirements can be resolved before files are changed. It also helps keep the proposed work small and consistent with the existing project.

Command for Claude CodeOpenCode

Written for Claude Code and OpenCode: $ARGUMENTS substitution, but also installed under .opencode/. Also seen: mentions AGENTS.md.

This is ondata/ckan-mcp-server's own configuration. It tells Claude Code and OpenCode how to work on ckan-mcp-server 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 ckan-mcp-server 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

openspec-proposal 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.

Origin

This is a copy

92% identical to OpenSpec: Proposal — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

The user has requested the following change proposal. Use the openspec instructions to create their change proposal. $ARGUMENTS

Guardrails

  • Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
  • Keep changes tightly scoped to the requested outcome.
  • Refer to openspec/AGENTS.md (located inside the openspec/ directory—run ls openspec or openspec update if you don't see it) if you need additional OpenSpec conventions or clarifications.
  • Identify any vague or ambiguous details and ask the necessary follow-up questions before editing files.
  • Do not write any code during the proposal stage. Only create design documents (proposal.md, tasks.md, design.md, and spec deltas). Implementation happens in the apply stage after approval.

Steps

  1. Review openspec/project.md, run openspec list and openspec list --specs, and inspect related code or docs (e.g., via rg/ls) to ground the proposal in current behaviour; note any gaps that require clarification.
  2. Choose a unique verb-led change-id and scaffold proposal.md, tasks.md, and design.md (when needed) under openspec/changes/<id>/.
  3. Map the change into concrete capabilities or requirements, breaking multi-scope efforts into distinct spec deltas with clear relationships and sequencing.
  4. Capture architectural reasoning in design.md when the solution spans multiple systems, introduces new patterns, or demands trade-off discussion before committing to specs.
  5. Draft spec deltas in changes/<id>/specs/<capability>/spec.md (one folder per capability) using ## ADDED|MODIFIED|REMOVED Requirements with at least one #### Scenario: per requirement and cross-reference related capabilities when relevant.
  6. Draft tasks.md as an ordered list of small, verifiable work items that deliver user-visible progress, include validation (tests, tooling), and highlight dependencies or parallelizable work.
  7. Validate with openspec validate <id> --strict and resolve every issue before sharing the proposal.

Reference

  • Use openspec show <id> --json --deltas-only or openspec show <spec> --type spec to inspect details when validation fails.
  • Search existing requirements with rg -n "Requirement:|Scenario:" openspec/specs before writing new ones.
  • Explore the codebase with rg <keyword>, ls, or direct file reads so proposals align with current implementation realities.

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.
