Built for quant developers, kdb+ DBAs, and trading infrastructure teams. Catches: Type errors in implicit casts (e.g., mixing longs and floats in comparisons) Rank errors from wrong argument counts in function calls Unescaped signals in protected evaluation Memory-inefficient queries (selecting all columns when only some are needed) Missing peach parallelism opportunities for embarrassingly parallel operations Unsafe eval/value usage on user-supplied strings (Q injection) Unlocked tables during concurrent inserts Missing \`g# grouped attributes on high-cardinality join columns N-squared joins that should be aj (asof joins) or wj (window joins) Race conditions in timer callbacks (.z.ts) Unprotected IPC handlers (.z.pg, .z.ps) and exposed .z.pw Strictness modes: ModeWhat it checksstandardBugs, correctness, type errors, join semantics, null handlingstrictEverything in standard + performance (attributes, peach, vector ops) + stylesecurityEverything in standard + injection via string eval, unprotected IPC handlers, exposed .z.pw, port exposure Intelligent routing via Astrai: Complex algorithmic Q (custom signal generation, real-time CEP) routes to powerful models. Simple table operations (selects, inserts, schema definitions) route to cheaper, faster models. You get the best result at the lowest cost. BYOK (Bring Your Own Keys): Your provider API keys, your billing. Astrai routes to the best model among your configured providers. ### Setup Get a free API key at as-trai.com Set your API key: export ASTRAI_API_KEY="your_key_here" Optionally add provider keys for BYOK routing: export ANTHROPIC_API_KEY="sk-ant-..." export OPENAI_API_KEY="sk-..." Run /review-q on any .q file ### Usage /review-q Review current Q file /review-q --strict Strict mode: bugs + performance + style /review-q --focus security Security mode: eval injection, IPC, .z.pw /review-q --file tick.q Review a specific file ### Example output Reviewing tick.q (strict mode)... Model: claude-opus-4-6 via Astrai Found 3 issues: [CRITICAL] Line 12: Missing \`s# attribute on time column \`trade\` table uses \`aj\` but \`time\` column lacks sorted attribute. Without \`s#\`, asof join scans linearly — O(n) instead of O(log n). Fix: trade: \`trade upsert update \`s#time from trade [WARNING] Line 34: Using \`each\` where vector operation suffices {x*y} each' (price;qty) can be replaced with price*qty Vector multiply is ~100x faster than each-both. [INFO] Line 45: Consider \`peach\` for independent symbol processing Processing each symbol sequentially. Since operations are independent, \`peach\` would utilize all cores. Fix: results: func peach syms Summary: 1 critical, 1 warning, 1 info. Focus on the missing sorted attribute — it will cause aj performance to degrade from microseconds to milliseconds at scale. ### Environment Variables VariableRequiredDescriptionASTRAI_API_KEYYesAPI key from as-trai.comANTHROPIC_API_KEYNoBYOK: Anthropic provider keyOPENAI_API_KEYNoBYOK: OpenAI provider keyGOOGLE_API_KEYNoBYOK: Google AI provider keyDEEPSEEK_API_KEYNoBYOK: DeepSeek provider keyMISTRAL_API_KEYNoBYOK: Mistral provider keyGROQ_API_KEYNoBYOK: Groq provider keyTOGETHER_API_KEYNoBYOK: Together AI provider keyFIREWORKS_API_KEYNoBYOK: Fireworks AI provider keyCOHERE_API_KEYNoBYOK: Cohere provider keyPERPLEXITY_API_KEYNoBYOK: Perplexity provider keyREVIEW_STRICTNESSNoDefault strictness: standard, strict, or security ### External Endpoints EndpointPurposeas-trai.com/v1/chat/completionsAstrai inference router — routes Q review requests to the optimal model ### Security & Privacy No code storage: Your Q code is sent to the selected AI provider for inference and is not stored by Astrai. BYOK: When you provide your own provider keys, requests go directly through Astrai's router to your provider account. Astrai does not store or log your provider keys beyond the request lifecycle. Transport: All communication uses HTTPS/TLS. No telemetry: The skill does not send analytics or telemetry data. Only the review request goes to Astrai. Local processing: File reading and result formatting happen entirely on your machine. ### Why Q needs specialized review Q is unlike any mainstream programming language: Extreme terseness: A single line of Q can express what takes 20 lines in Python. This density makes bugs nearly invisible during manual review. Implicit type coercion: Q silently coerces types in many operations. Comparing a long to a float, or joining on mismatched key types, can produce silently wrong results. 1000x performance gaps: The difference between idiomatic and naive Q is not 2x or 10x — it is often 1000x. Missing a sorted attribute on a time column turns an O(log n) asof join into O(n). Using each instead of vector operations adds interpreter overhead per element. Adverb complexity: Q's adverbs (/, \\, ', /:, \\:, ':) modify function behavior in powerful but subtle ways. +/ is reduce-add, +\\ is scan-add, +' is each-both-add. Confusing these causes wrong results, not errors. Most AI models struggle: Without Q-specific prompting, general-purpose AI models treat Q code as line noise. This skill provides detailed system prompts that teach the model Q semantics, kdb+ internals, and finance-domain patterns. ### Pricing Uses Astrai's inference routing. Your costs depend on the models selected: PlanRateIncludesFree$01,000 requests/dayPro$49/mo50,000 requests/day, priority routingBusiness$199/moUnlimited requests, dedicated support With BYOK, you pay your provider directly at their rates.
