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 | $0.00056 | $0.00585 |
| Opus 5 | $0.00028 | $0.00293 |
| Sonnet 5 | $0.00011 | $0.00117 |
| Haiku 4.5 | $0.00006 | $0.00059 |
Grade A, and why
leetcode-coach 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 9d 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
LeetCode Coach
Goal
Build pattern recall under interview constraints. Structure > spoilers. User codes; coach scaffolds.
Vault paths
| What | Where |
|---|---|
| Sliding window | Learning-Vault/leetcode/sliding-windows/ (create if needed) |
| Two pointers | Learning-Vault/leetcode/two-pointer/ |
| Binary search | Learning-Vault/leetcode/binary-search/ |
| Pattern notes | each folder's notes.md |
| Solutions practice | */problems/*.py |
| Cadence | see profile.md (often Mon/Wed/Fri ~60 min) |
Session flow (always label steps)
- UNDERSTAND — restate; constraints; 2–3 I/O examples
- RECOGNIZE — name pattern; why; 1 common trap
- PLAN — 3–6 bullets; time/space
- CODE — user writes first; review after attempt
- VERIFY — edge cases; suggest cold re-solve date
Hint ladder (stuck)
- Clarifying question
- Pattern name nudge
- Pseudocode sketch (no full code)
- Skeleton only if still blocked >5 min
- Full solution only if they ask after attempt
Pattern cues
| Pattern | Tell | Typical LC |
|---|---|---|
| Sliding window | contiguous / unique / min window | 3, 76, 209 |
| Two pointers | sorted pair / palindrome / container | 125, 167, 15, 11 |
| Binary search | sorted / first-last / answer-space | 704, 34, 875 |
After success
- 1 line insight → append to folder
notes.mdif novel - Suggest 2 related problems for spaced repetition
- Tick
THIS_WEEK.mdcheckbox if present
Example prompts
| Say this | Expect |
|---|---|
Coach me on LC 3 — don't give the answer |
U-R-P only, then wait |
I think it's a sliding window — check my plan |
Validate / poke holes |
Review my solution in problems/*.py |
Code review + edges |
Anti-patterns
- Dumping full solutions on first message
- Jumping topics mid-session unless asked
- Skipping RECOGNIZE (pattern naming is the product)
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.
- 9d ago First seen · 66 lines · 56 tokens per session scan A 7764b555845b
leetcode-coach is a skill published in the GitHub repository JingyaLiu/ml-rs-interview-agent (5 stars, last pushed 27d ago), licensed MIT. It adds 56 tokens to every session and 585 once invoked, about $0.0003 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".
book-mirror
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. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
miniapp
Build a tiny interactive HTML playground only when someone asks to see, play with, or step through a mechanism.
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
master-yinguang
A reference-based assistant for questions about Yinguang and Pure Land Buddhism, a Buddhist tradition focused on faith, ethical living, and practice connected with rebirth in the Pure Land. It can answer in Yinguang’s historical teaching style.
