Claude Code Ultimate Guide is a structured documentation project for learning how to build, operate, and govern coding agents with Claude Code. It serves developers and teams through guidance on agentic workflows, hooks, skills, MCP servers, security, and adoption. The catalogue entries are reusable skills, commands, agents, hooks, instructions, settings, and a plugin drawn from the guide's workflow materials.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.01571 |
| Opus 5.5 | $0.00024 | $0.00628 |
| Sonnet 5.5 | $0.00012 | $0.00314 |
| Haiku 4.5 | $0.00006 | $0.00157 |
Grade A, and why
release-notes-generator 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 19d 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.

Licensed CC-BY-SA-4.0
The repository is licensed CC-BY-SA-4.0, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

release-and-changelog
Use when cutting a release, bumping a version, or writing release notes. Activate for keywords like "release", "version bump", "changelog", "release notes", "tag", "publish", "ship a release", "v1.x", "v2.x". Enforces version hygiene: SemVer respect, changelog discipline, atomic commits, tagged release. Always reflect…
git
Git version control best practices: branching, commits, merging, conflict resolution, PR workflows. Use when managing branches, creating commits, merging code, or resolving conflicts.
aio-github
Read and manage GitHub repos, pull requests, issues, releases, and branches via github-mcp (auto-installs if missing). Use when the user mentions a GitHub URL, asks to open/review/merge a PR, comment on an issue, list repos, trigger a release, or run any GitHub action programmatically.
release
Generate or update changelog and release notes from project history.
memstack-development-changelog-generator
Use when the user says 'generate changelog', 'update changelog', 'what changed', 'release notes', 'write changelog', or needs a formatted CHANGELOG.md from git commit history. Do NOT use for diary entries, git log viewing, or commit message writing.
git-release
Draft release notes from merged PRs, propose a semver bump, and emit a copy-pasteable gh release create command. Use when preparing a tagged GitHub release.
