gitlab-mcp-server: Skill for Claude Code

.github/skills/update-starlight-docs/SKILL.md

update-starlight-docs is a skill for Claude Code, Codex from jmrplens/gitlab-mcp-server. It costs 62 tokens per session (3,999 once invoked), scanned A, original, MIT.

A documentation-maintenance workflow for Astro Starlight, a documentation site framework. It updates user-facing documentation when code changes affect features, configuration, deployment, or behavior, while also accounting for a separate contributor documentation set.

In plain words
What is it for?
Use it after adding tools, configuration options, capabilities, transport changes, error handling, security changes, or automatic-update behavior. It maps each change to pages such as the tools reference, configuration guide, troubleshooting, and security documentation.
Why use it?
It helps prevent the user documentation from falling behind the product. It also identifies the affected English and Spanish pages and requires related developer documentation to be updated.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is jmrplens/gitlab-mcp-server's own configuration. It tells Claude Code and Codex how to work on gitlab-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 gitlab-mcp-server configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go run ./cmd/format_md_tables/ --check # the site's tables belong to this formatter, not to prettier.

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.

Fable 5.1 $0.00062 $0.03999
Opus 5.5 $0.00025 $0.01600

Security

Grade A, and why

update-starlight-docs scanned grade A with 1 finding 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 6d 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.

Update Starlight Documentation

Update the Astro Starlight user documentation site to reflect code changes that affect user-facing features, configuration, or behavior.

Before Starting

  1. Identify what changed in the code that affects users
  2. Read the current Starlight docs structure: site/src/content/docs/
  3. Determine affected pages (EN and ES)
  4. Check whether a generator writes the page or the figure (table below); if one does, change its source and run it instead of editing

Where Documentation Lives

The site is the only home of the user documentation, in English and Spanish. docs/ keeps contributor material only, under docs/development/, and the README is a short landing page that links the site (ADR-0025).

Audience Path Format
Users site/src/content/docs/ (English) and site/src/content/docs/es/ (Spanish) MDX (Starlight)
Contributors and AI agents docs/development/, CLAUDE.md, AGENTS.md, .github/ Markdown

Rule: a change to user-facing behavior updates the site page that describes it, in English and in Spanish, in the same change. A contributor-only change (a gate, a generator, a convention) goes to docs/development/ or CLAUDE.md, and never to the site. There is no second copy of a user page anywhere in the repository to keep in step.

Pages and data a generator writes

Never edit these by hand: change the source the generator reads, then run it. make update-all runs every Go command in this table, the benchmark through its redraw target; the last row is the site build's own.

What Source Command
reference/tools/<group>.mdx and its es/ twin, one page per catalog group, named after the group's tool name without gitlab_ and with hyphens (gitlab_merge_request is merge-request.mdx), and the index.mdx beside them the action catalog and cmd/gen_tool_reference/domains.json make gen-tool-reference
reference/fine-grained-permissions.mdx and its es/ twin the handlers and docs/development/gitlab-api-live.json make gen-action-grants
The block between {/*START BENCHMARK*/} and {/*END BENCHMARK*/} of performance/resource-benchmark.mdx in both languages, the charts under site/public/benchmarks/, and site/src/data/resource-benchmark.json a measurement of the binary make bench-resources measures; make bench-resources-render redraws from the committed record
site/src/data/stats.json, the counts (tools, meta-tools, actions, groups, resources, prompts) the pages print as {stats...} the catalog and the registered surfaces make gen-site-stats
site/src/data/token-footprint.json a token measurement of every tier, surface and meta schema mode make gen-footprint
The site's own /llms.txt and /es/llms.txt the content collection and the SECTIONS table of site/scripts/gen-llms.mjs written by pnpm run build, never committed

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.
