Writing Claude Skills
1 882 writing skills from 445 authors. They draft and edit prose. Half of them fit into 1 924 tokens or less — that is what one costs your context window when the agent loads it. 283 ship runnable scripts rather than instructions alone. We also found 239 copies of these same skills sitting in other people's repositories — counted once here, not 239 times.

The operating doctrine, self-contained in this folder. Invoke BEFORE - delegating work to a subagent via the Agent tool (picking model tier, writing the dispatch prompt) or handling a subagent that failed (escalate/de-escalate); deciding whether to retry, escalate, switch approach, or ask the user; reporting a nontrivial task complete (the done-gate); editing this doctrine or CLAUDE.md; recording a lesson about the harness.
Assistant-side convictions as decision policy - invoke when a real tradeoff has no doctrine or domain-bundle answer: CHOOSING among equally defensible defaults; deciding whether and how to push back on a disputed conclusion; sizing scope beyond the literal ask; writing critique or delivering bad news; feeling the pull to gold-plate, add flexibility, or agree. Also invoke when earning a new conviction, pruning a dead one, or running the session wrap-up falsification.

Use when writing a symmetric Bollinger-band mean-reversion strategy on the 4h timeframe — anything described as BB reverter, range trader, chop strategy, ADX-gated mean reversion, band-fade with ROI ladder. Long-or-short on 2σ band touches with RSI confirmation, gated to ADX<25 range regimes. Validated +8.77%/65.5% win across BTC/ETH/SOL/DOGE over 162d; depends entirely on its minimal_roi ladder (2.5% → 1.5% → 0.5% → breakeven). Pairs with donchian-strong-regime for full-regime coverage.
Use when writing a swing/intraday breakout strategy on Superior Trade — anything described as breakout, momentum, trend following, 12-hour high, range expansion, riding new highs, Donchian breakout. Note this template was unprofitable in our reference backtest (long-only in a -13% market); explain regime sensitivity to the user.
Use when writing a trend-breakdown short gated by a triple-confirmed strong-bear regime on Superior Trade — anything described as donchian short, structural breakdown, regime-gated trend follower, EMA-separation + ADX + N-bar return confirmation. Validated +6.69%/100% win/0% DD on BTC over 162d; designed to fire only in confirmed bear regimes (zero trades in chop by design). Pairs with bollinger-reverter-4h for full-regime coverage.
Use when writing a funding-rate-driven perp strategy on Superior Trade — anything described as funding harvest, funding arbitrage, funding rate carry, negative funding, paid to long, paid to short, basis trade. The strategy reads Hyperliquid hourly funding via `dp.get_pair_dataframe(candle_type="funding_rate")`, which is automatically downloaded for backtests.
Use when writing a strategy that captures short-squeeze setups on Hyperliquid perps — anything described as squeeze, short squeeze fuel, negative funding rally, fade the shorts, paid to long. Goes long when funding APR is deeply negative (shorts paying longs) AND price has been rising, exits on funding normalisation or time-stop. Sibling of strategy-funding-harvest but reads the squeeze-fuel signal instead of the carry.
Use when writing a high-turnover intraday strategy on Superior Trade — anything described as scalping, momentum bursts, fast in/out, RSI thrust, volume spike entry, 5-minute strategy. Note this template was unprofitable in our reference backtest (33% WR, -0.34%); use it as a structural template, not a recommendation.
Use when writing a Bollinger-band mean-reversion strategy on Superior Trade — anything described as mean reversion, BB bands, oversold bounce, fade, range trade, ADX low, sigma extension. Upgraded 2026-05-18 from the prior 1h/2.5σ variant to the validated 4h/2σ/ADX<25 version (+8.77% multi-pair, 65.5% win over 162d). Prior 1h variant is preserved at the end of the file as an archived reference.
