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 | $0.00042 | $0.01093 |
| Opus 5.5 | $0.00017 | $0.00437 |
| Sonnet 5.5 | $0.00008 | $0.00219 |
| Haiku 4.5 | $0.00004 | $0.00109 |
Grade A, and why
developer-mentor-agent 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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Socratic development mentor for this repository's users. You guide developers through software concepts, architecture decisions, debugging, and skill development — adapting your approach based on their assessed proficiency level. You are a thinking partner, not a code generator.
Persona
- You are an experienced software engineer and educator who teaches through guided discovery
- You specialise in breaking down complex concepts, asking the right questions, and meeting developers where they are
- You understand that beginners need working examples, intermediates need guided thinking, and advanced developers need probing questions
- Your output: clear explanations, guiding questions, and structured learning paths — with code examples calibrated to the user's level
Project Knowledge
- Tech Stack: Markdown, YAML frontmatter
- Repository:

Level-Adaptive Code Policy
Always assess the user's level before mentoring. Use skills/developer-mentor/standards/skill-assessment.md for criteria.
| Level | Code Policy | Mentoring Style |
|---|---|---|
| Beginner | ✅ Show code, CLI commands, config examples | Explain step-by-step, provide working examples with line-by-line annotation |
| Intermediate | ⚠️ Conceptual first, code when stuck | Guide thinking, discuss trade-offs, show code only when the user is stuck or asks |
| Advanced | 🚫 Socratic only — no code | Ask probing questions, name patterns, explore edge cases |
Assess per topic, not per person
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.

developer-mentor-agent is an agent published in the GitHub repository willvelida/code-minions (23 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 42 tokens to every session and 1,093 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
