Use for a known bottleneck; not unbiased A/B comparison.\"\n---\n\n# Performance Optimizer\n\n**Goal:** Optimize only measured problems. Preserve correctness, isolate experiments, and retain a change only when comparable evidence shows that it improves the agreed metric without unacceptable regressions.\n\n**Execution contract:** Treat the ordered checkbox workflow below as this skill's Definition of Done. Track every checkbox as `PENDING`, then resolve it to `PROVEN` with concrete evidence, `CLEARED` with evidence that its conditional trigger is absent, or `UNPROVEN`; reading, mentioning, delegating, skipping, or tool failure is not proof.\nBefore returning, resolve every `PENDING`, count only `PROVEN` and `CLEARED` items as complete, apply this skill's verdict, decision, and approval rules to every `UNPROVEN`, and prepend **Checklist: X/Y complete**<br>**Incomplete: None | section/item — reason; outcome impact; exact next action**; list every `UNPROVEN` item.\n\n## Tool Routing\n\n| Need | Preferred tool | Use it when | Fallback |\n|---|---|---|---|\n| Repository state and safe edit boundary | Git status, diff, branch or worktree inspection, and repository instructions | Always before profiling or editing | Stop if user changes cannot be isolated safely |\n| Baseline and final metric | Existing benchmark, load test, reproducible command, or production-like replay | The metric and workload reflect the reported problem | Create the smallest local benchmark that reproduces the behavior without inventing production scale |\n| Bottleneck evidence | Existing profiler, tracing, query diagnostics, allocation tools, or OS-level metrics | Locating CPU, memory, I/O, lock, query, network, or scheduler cost | Targeted instrumentation with cleanup plan |\n| Code path and blast radius | Language server or host-native code intelligence | Following hot symbols, callers, implementations, and affected contracts | Narrow search plus direct inspection of definitions and consumers |\n| Correctness and regressions | Repository-defined tests, build, lint, type, and smoke commands | Before and after every retained experiment | Choose the smallest portfolio action when current evidence cannot detect the likely material regression |\n| Runtime and dependency semantics | Official documentation, release notes, and specifications matching installed versions | A hypothesis depends on optimizer, runtime, database, framework, or library behavior | Primary-source web research; otherwise mark the hypothesis `UNVERIFIED` |\n| Independent challenge | One native subagent or advisor when policy and scope allow | Competing hypotheses, unfamiliar runtime behavior, or high-risk change needs independent scrutiny | Separate adversarial hypothesis review |\n\nDo not optimize by aesthetic preference or benchmark a different workload from the reported problem. Never discard user changes, use destructive Git reset, or run uncontrolled load against production.\n\n## Evidence Rules\n\n- Define the primary metric and acceptance threshold before editing; do not move the goal after seeing results.\n- Compare the same workload, environment, build mode, data, warmup, and measurement method before and after.\n- Use repeated runs and report distribution or variance; a single faster run is not proof.\n- Separate cold-start, warm steady-state, and saturated-load behavior when the reported problem can occur in more than one regime.\n- Profile contribution and end-to-end impact separately: a hot function can improve while the user-visible metric does not.\n- Treat profiler estimates, synthetic workloads, and production observations as different evidence classes and label them.\n- Correctness, resource safety, and operational stability are hard constraints, not secondary metrics.\n\n## Checklist\n\n### 1. Define the Problem and Protect the Workspace\n\n- [ ] Resolve the user-visible problem, affected workflow, target metric, workload, environment, constraints, and acceptance threshold.\n- [ ] Run the wrong-tool gate: confirm the symptom is a performance problem rather than correctness, configuration, capacity, dependency, or observability failure.\n- [ ] Read repository instructions and inspect Git state, branches, uncommitted changes, ignored artifacts, and available isolation mechanisms.\n- [ ] Preserve user work and isolate experiments in a safe branch or worktree when changes, benchmarks, or generated artifacts could interfere.\n- [ ] Start a run-owned resource ledger with every created absolute path, worktree, process ID, cache, profile, and temporary artifact; never register pre-existing resources as cleanup targets.\n- [ ] Identify correctness, security, memory, cost, compatibility, and operational constraints that no optimization may violate.\n- [ ] Locate existing benchmarks, profiles, performance tests, production traces, service-level objectives, and known environmental variability.\n\n### 2. Establish a Reproducible Baseline\n\n- [ ] Use the same metric type as the observed problem: latency distribution, throughput, CPU, memory, allocation, I/O, query count, lock wait, or another direct measure.\n- [ ] Make the workload representative and deterministic enough to compare, including data size, concurrency, cache state, warmup, and build mode.\n- [ ] Cover the operating points that could reverse the conclusion--at minimum the reported case plus relevant data-size or concurrency boundaries--without inventing synthetic scale.\n- [ ] Run enough repetitions to expose noise and record raw results, median or appropriate percentile, spread, failures, and environment details.\n- [ ] When drift or noise is material, interleave or randomize baseline and candidate runs and prefer paired comparisons over one block of \"before\" followed by one block of \"after.\"\n- [ ] Verify that the benchmark detects an intentionally slower or obviously changed path when practical; a benchmark insensitive to behavior cannot validate optimization.\n- [ ] Run relevant correctness tests before editing so pre-existing failures are not attributed to experiments.\n- [ ] Stop and report `BLOCKED` if the problem cannot be reproduced and no trustworthy production evidence can define a safe proxy.\n\n### 3. Profile and Form Hypotheses\n\n- [ ] Profile the end-to-end path before focusing on a function, query, allocation, lock, or network call.\n- [ ] Build a ranked cost map with measured contribution, call frequency, inclusive and exclusive cost where available, and affected workload.\n- [ ] Trace the top costs to implementation, callers, data shape, concurrency model, configuration, and external dependencies.\n- [ ] Distinguish root bottlenecks from downstream symptoms, measurement overhead, debug builds, cold starts, and one-time initialization.\n- [ ] If profiling crosses services or processes whose code is in scope, align traces/correlation IDs and follow the measured downstream path; do not label an accessible internal service \"external\" and stop at its latency.\n- [ ] Estimate profiler or instrumentation perturbation and confirm the final end-to-end result without invasive instrumentation.\n- [ ] Research official runtime, framework, database, and dependency behavior only when it can confirm or reject a concrete hypothesis.\n- [ ] Check existing platform and dependency capabilities before proposing custom caches, pools, schedulers, serializers, or data structures.\n- [ ] Write a small ordered hypothesis set; for each state expected metric change, mechanism, affected files, risk, dependencies, and verification.\n- [ ] Reject hypotheses that lack a measurable mechanism, require speculative scale, or cannot be rolled back independently.\n- [ ] Use an independent challenge when competing explanations remain plausible; verify advisor claims before changing code.\n\n### 4. Execute Atomic Keep-or-Discard Experiments\n\n- [ ] Map each risky hypothesis to existing proof and the material regression it could cause; implement `KEEP`, `ADD`, `UPDATE`, `MERGE`, `DELETE`, or justified `NO_TEST` within the approved test scope to produce the smallest trustworthy safety evidence, remove superseded testware, and retire temporary characterization proof when its trigger ends.\n- [ ] For caching, batching, parallelism, pooling, or retry changes, explicitly protect invalidation, ordering, idempotency, cancellation, backpressure, timeout, and bounded-resource semantics that the faster path could violate.\n- [ ] Apply the smallest coherent change that tests one mechanism; group changes only when their effects are intentionally inseparable.\n- [ ] Keep instrumentation bounded, low-overhead, and easy to remove; never leave secrets or sensitive payloads in diagnostic output.\n- [ ] Run focused correctness checks immediately after the edit and discard the experiment if they fail.\n- [ ] Repeat the exact baseline benchmark under comparable conditions and preserve raw results.\n- [ ] Inspect the diff for accidental cleanup, unrelated refactoring, generated churn, debug flags, changed benchmark inputs, and hidden configuration changes.\n- [ ] Mark the experiment `KEEP` only if the agreed metric improves beyond noise and all constraints pass.\n- [ ] Mark it `DISCARD` and revert only that experiment when the target is missed, results regress, or safety becomes uncertain.\n- [ ] After a kept change, establish the new compound baseline before testing the next hypothesis.\n\n### 5. Stop, Verify, and Report\n\n- [ ] Continue only when new measurement supports another hypothesis; stop at the target, diminishing returns, exhausted safe options, or a missing prerequisite.\n- [ ] Run the full relevant build, lint, type, test, smoke, benchmark, and operational checks on the final retained state.\n- [ ] Remove only run-owned ledger entries: verify absolute paths remain inside approved temporary roots, stop exact recorded process IDs, preserve dirty or pre-existing worktrees, and retain evidence artifacts intentionally reported.\n- [ ] Confirm that the benchmark definition and acceptance threshold did not drift during the run.\n- [ ] Report every kept and discarded hypothesis, not only the successful path, so future work does not repeat disproven experiments.\n- [ ] Use `IMPROVED` only when at least one retained change improves the agreed metric beyond noise with every constraint passing; use `NO_CHANGE` when all experiments are discarded and the baseline is restored; use `BLOCKED` when a safety prerequisite, reproducible baseline, or safe restoration path is unavailable.\n- [ ] Return the verdict with baseline, final distribution, delta, correctness evidence, limitations, and residual bottlenecks.\n\n## Output Contract\n\n```markdown\n# Performance Optimization\n\n**Verdict:** IMPROVED | NO_CHANGE | BLOCKED\n\n## Target and method\n- User-visible problem and workload\n- Primary metric and acceptance threshold\n- Environment, repetitions, and variance method\n- Correctness and operational constraints\n\n## Baseline and profile\n| Metric | Baseline | Variance | Evidence |\n|---|---:|---:|---|\n| ... | ... | ... | ... |\n\n## Experiments\n| Hypothesis | Change | Result | Decision | Verification |\n|---|---|---|---|---|\n| ... | ... | ... | KEEP / DISCARD | ... |\n\n## Final result\nComparable before/after metrics, full verification, cleanup, limitations, and residual bottlenecks.\n\n## Test portfolio decisions\nAffected evidence, material regression, action, oracle, gate and result, removed testware, and any review or retirement trigger; use `None` when existing proof remained sufficient and unchanged.\n\n## Evidence artifacts\nRun-owned paths and hashes for raw samples, commands, environment capture, final diff, and cleanup proof.\n```\n","tagline":"Optimizes a measured latency, throughput, memory, CPU, or I/O problem through profiling and keep-or-discard experiments.
