dataverse-mcp: Skill for Claude Code

.claude/skills/changelog/SKILL.md

changelog is a skill for Claude Code from ryanmichaeljames/dataverse-mcp. It costs 12 tokens per session (506 once invoked), scanned A, original, MIT.

A project skill for maintaining a CHANGELOG.md file, which records user-visible changes between releases. It follows the Keep a Changelog format and places new entries under “Unreleased.”

In plain words
What is it for?
Use it after adding, changing, fixing, or removing user-facing tools or options, including security-related changes.
Why use it?
It removes the guesswork from deciding what belongs in release notes and keeps entries focused on changes users can understand.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is ryanmichaeljames/dataverse-mcp's own configuration. It tells Claude Code how to work on dataverse-mcp 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 dataverse-mcp 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

changelog 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 1mo 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

Changelog - Keep a Changelog v1.1.0

Update CHANGELOG.md with entries for the current changes. Always write under ## [Unreleased].

Categories

Use only what applies — omit the rest:

  • Added — new tools or new options on existing tools
  • Changed — changed behavior of existing tools
  • Fixed — bug fixes
  • Removed — tools or options removed
  • Security — security fixes

Entry rules

  • One bullet per logical change, not per file or function
  • Name the tool in backticks: `dataverse_list_tables`
  • Describe what it does for the user, not how it's implemented
  • Omit HTTP internals, refactors, dependency bumps, and test changes
  • Keep each bullet to one sentence — enough to understand the impact

What to skip

Do not add entries for:

  • Internal refactors with no user-visible effect
  • Dependency version bumps
  • Code style or formatting changes
  • Test additions or changes
  • Documentation-only changes

Example

## [Unreleased]

### Added
- `dataverse_get_foo` tool to retrieve foo records by ID

### Security
- `dataverse_delete_bar` now requires `DATAVERSE_ALLOW_DELETE=true` to prevent accidental deletions

## [1.2.0] - 2026-05-01

### Added
- `dataverse_list_bars` tool to list bar records with optional status filter

### Changed
- `dataverse_get_foo` now returns `displayname` in addition to `id`

### Fixed
- `dataverse_list_foos` no longer returns duplicate entries when a filter is applied

### Removed
- `dataverse_legacy_query` tool removed; use `dataverse_query_table` instead

## [1.1.0] - 2026-04-01

### Added
- `dataverse_query_table` tool to query records with OData filter and column selection

Steps

  1. Read CHANGELOG.md
  2. Review the diff or description of changes
  3. Identify the correct categories and write concise bullets
  4. Insert them under ## [Unreleased], creating category headers as needed
  5. Do not modify any released version sections

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.
