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 5.5 | $0.00022 | $0.00234 |
| Sonnet 5.5 | $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 2mo 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.
- 2mo 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 2mo ago), licensed MIT. It adds 56 tokens to every session and 585 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 2026-08-31.

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…
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
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.
