What it does
Chess Opening Coach is an agent skill from mohitagw15856/pm-claude-skills. Build a small, coherent opening repertoire that fits your style and level — the few lines actually worth learning, plus the plans and traps behind them. Use when asked what chess opening should I learn, build me a repertoire, help with my openings, or what to play against [opening]. Produces a compact repertoire for White and Black keyed to your rating and style, the main ideas and typical plans (not just moves to memorize), the common traps to know from both sides, and what to study next — kept small enough to…
Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked what chess opening should I learn
- Build me a repertoire
- Help with my openings
- What to play against [opening]
Example prompts
- “/chess-opening-coach”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Fit the style. Recommend openings that suit how the player likes games to go — an aggressive player will hate a dry, maneuvering system.
- Teach plans over moves. For each opening, give the middlegame plan and typical pawn breaks so they know why, not just what.
- Keep it small. A few reliable lines beat a sprawling repertoire — depth of understanding over breadth of memorization.
- Cover the real replies. Address the responses they'll actually meet at their level, not obscure grandmaster theory.
- Know the traps. Flag the common early tricks (both to avoid and to spring) that decide games at club level.
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Chess Opening Coach loads about 981 tokens when it runs. Until then it costs about 138 tokens; SKILL.md has 495 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Build a small, coherent opening repertoire that fits your style and level — the few lines actually worth learning, plus the plans and traps behind them. Use when asked what chess opening should I learn, build me a repertoire, help with my openings, or what to play against [opening]. Produces a compact repertoire for White and Black keyed to your rating and style, the main ideas and typical plans (not just moves to memorize), the common traps to know from both sides, and what to study next — kept small enough to actually learn.
Chess Opening Coach
Most improving players lose games not in the opening but by drowning in opening theory they don't understand. This builds a small repertoire — a handful of coherent lines that suit how you like to play — and teaches the ideas behind them, so you reach playable middlegames you understand instead of memorizing twenty moves you'll forget.
What This Skill Produces
- A compact repertoire — one main choice for White, and answers for Black vs 1.e4 and 1.d4, sized to your level
- The ideas, not just moves — the plan behind each opening: pawn breaks, piece placement, where your pieces belong
- Traps both ways — the common tricks to avoid falling for and the ones you can use
- Move-order essentials — the few critical points where accuracy matters, and where you can play on understanding
- A study path — what to learn first and what to add later, so it stays small
Required Inputs
Ask for these if not provided:
- Rating/level — rough strength (beginner, club, intermediate) — sets how much theory is worth it
- Style — attacking/tactical, solid/positional, or "just something reliable"
- Colors & gaps — do you want White, Black, or both; anything you already play
- Time — how much you'll realistically study
- Trouble spots — openings you keep losing against
Framework: Small, Understood, Coherent
- Fit the style. Recommend openings that suit how the player likes games to go — an aggressive player will hate a dry, maneuvering system.
- Teach plans over moves. For each opening, give the middlegame plan and typical pawn breaks so they know why, not just what.
- Keep it small. A few reliable lines beat a sprawling repertoire — depth of understanding over breadth of memorization.
- Cover the real replies. Address the responses they'll actually meet at their level, not obscure grandmaster theory.
- Know the traps. Flag the common early tricks (both to avoid and to spring) that decide games at club level.

Output Format
Repertoire: [level] · style: [x] · [colors]
As White: [opening] — plan: [pawn breaks / piece setup]. Key point: [where accuracy matters]. As Black vs 1.e4: [defense] — main idea: […]. As Black vs 1.d4: [defense] — main idea: […].
Traps to know: [avoid: … / use: …]. Study first → later: [the 2–3 lines to learn now] → [what to add once comfortable].
Quality Checks
- Repertoire size matches the player's level (small for beginners)
- Each opening comes with plans/ideas, not just move lists
- Recommendations fit the stated style
- Covers the replies they'll actually face
- Includes common traps from both sides and a study order
Anti-Patterns
- A 20-move memorization dump the player won't retain or understand.
- Style mismatch — a sharp gambit for someone who wants solid.
- Only moves, no plans — leaving them lost once theory ends.
- Obscure theory irrelevant at their level.
- Too many openings to ever learn properly.
Example Trigger Phrases
- "What opening should I learn as a beginner who likes attacking?"
- "Build me a simple repertoire for White and Black."
- "I keep losing against 1.e4 — what should I play?"
- "Give me a solid, low-theory opening system."
- "Explain the plan behind the London System."
