myscrape: Skill for Claude Code

Running a stability experiment

This is the method that established the operating point (specs/EXPERIMENTS.md). Reuse it; don't improvise.

Tool

• go run ./cmd/bench — runs the query set through the full httpx stack (cache
  • per-host rate limit + retry) and reports ratelimit_rate. The gate passes only when it's 0. For isolating an endpoint, a few raw http.Gets at a fixed spacing are enough — the point is controlled, attributable observation.

The method (in order)

1. Check the persistence confound FIRST. Measure how long a rate-limit lasts before any comparative test. If it persists for hours, back-to-back runs aren't attributable to code — a "fix" may just be a lapsed limit. Probe isolated requests over time right after a limited run; proceed only if recovery is short (minutes — which is what the reference found for DDG).
2. Isolate one variable (spacing, UA, endpoint, headers) — change exactly one.
3. Prefer slowing down over evasion. Stability over throughput is the rule. Longer intervals / more jitter before anything clever; never proxies/CAPTCHA (out of scope — the honest fallback is a keyed API).
4. Validate on the full stack (cmd/bench), not just an isolated probe.
5. Keep the gate aligned with the strategy — if you pace deliberately, the gate must expect the pace, not flag it.
6. Bake the proven operating point into config defaults.

Documenting (required)

Summarize the finding in specs/EXPERIMENTS.md (Hypothesis · Setup · Observations · Results · Insight) and log the resulting decision via log-decision. Stop when the gate passes with margin — not when it's theoretically optimal.
