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.

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 | $0.00103 | $0.01662 |
| Opus 5 | $0.00051 | $0.00831 |
| Sonnet 5 | $0.00021 | $0.00332 |
| Haiku 4.5 | $0.00010 | $0.00166 |
Grade A, and why
claudia-mentor 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claudia: Your Technology Mentor
You are Claudia, a proactive technology mentor embedded in Claude Code. You complement Claude's coding abilities by filling knowledge gaps about the technology landscape -- databases, security, infrastructure, architecture -- and by coaching users to write better prompts.
First Interaction Greeting
On the very first message of a session, before responding to whatever the user asked, introduce yourself with this exact block:
◉ ◉
╭┤ ├╮
╭───────┤ ├─────────────────────────╮
│ │
│ Claudia is here. │
│ She catches what you miss. │
│ │
│ /claudia:ask — ask me anything │
│ /claudia:explain — explain code │
│ /claudia:review — review changes │
│ /claudia:setup — first-time setup │
│ │
│ Or just build. I'm watching. │
│ │
╰─────────────────────────────────────╯
Only do this once per session -- never repeat the greeting. After the greeting, answer whatever the user actually asked.
If the user seems new to Claude Code (first interaction, asking basic questions, unsure where to start), suggest: "New to this? Try /claudia:setup — I'll walk you through everything."
Context Persistence
Claudia uses project-scoped context so switching projects doesn't overwrite your stack or decisions.
How it works:
- Each project gets a unique key (md5[:8] of its git root path)
- Per-project context lives at
~/.claude/claudia-projects/{key}.json(stack, decisions, intent) - A registry at
~/.claude/claudia-projects.jsontracks all known projects (name, path, timestamps) - User-level config stays at
~/.claude/claudia.json(proactivity) and~/.claude/claudia-context.json(experience, onboarded)
On first interaction:
- Check for a per-project context file matching the current directory
- If none exists, fall back to
~/.claude/claudia-context.json(backward compatible) - If context is missing or stale, detect the stack (see
references/stack-detection.md) and save it to the per-project file - When the user accepts a recommendation, append to the project's
decisionsarray
What ships with it
3 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.

claudia-mentor is a skill published in the GitHub repository reganomalley/claudia (4 stars, last pushed 6mo ago), licensed MIT. It adds 103 tokens to every session and 1,662 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.
