serpapi-performance-tuningMeasure and improve SerpAPI latency, payload size, connection reuse, caching, and concurrency without breaking freshness or allowance controls.
Serpapi Performance Tuning is an agent skill from jeremylongshore/tons-of-skills-marketplace. Measure and improve SerpAPI latency, payload size, connection reuse, caching, and concurrency without breaking freshness or allowance controls. Use when search performance misses an SLO. Trigger with "tune SerpAPI performance".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code; production cache, output, or concurrency changes require owner approval and measured rollback criteria
It sits in DevOps & Cloud, covering Site reliability engineering and Caching. It works with SerpApi. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepWebFetchWriteEditFrom allowed-tools in the SKILL.md frontmatter.
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.
Links to these hosts (documentation or services it may open):
serpapi.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
SERPAPI_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code; production cache, output, or concurrency changes require owner approval and measured rollback criteria
From compatibility in the SKILL.md frontmatter.
Serpapi Performance Tuning loads about 1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 400 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.
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.

.claude/skills/serpapi-performance-tuning/SKILL.md (or your agent's skills folder).Optimize the measured bottleneck while preserving result freshness, schema correctness, privacy, and account capacity.
Use Read, Glob, and Grep to inspect call paths and instrumentation, WebFetch to verify current cache and output features, and Write or Edit for measurements, cache layers, field selection, tests, and rollback controls.
For an exactly matching parameter set, SerpAPI may serve its one-hour server cache; cached searches are free and do not count toward monthly searches. no_cache=true forces a fresh fetch and must not be combined with async. JSON Restrictor reduces selected JSON fields, and output=md provides token-efficient Markdown for agent use.
Keep SERPAPI_KEY outside measurement labels, cache keys, traces, and profiles. Treat query values and result bodies according to their data classification.
Return the baseline profile, bottleneck, proposed and measured changes, cache-key/TTL contract, output format, capacity impact, canary results, and rollback thresholds.
| Condition | Response |
|---|---|
| Cache serves semantically wrong data | Disable the layer and expand the normalized key contract. |
no_cache raises usage unexpectedly | Remove it unless the freshness requirement explicitly justifies fresh fetches. |
| Parallelism causes 429s | Reduce admissions and coordinate through the shared limiter. |
| Field restriction breaks parsing | Restore required fields and lock the projection with fixtures. |
engine=google; baseline_p95=measured; bottleneck=payload; change=json-restrictor; freshness=1h; search_delta=0; schema-tests=pass; rollback=feature-flagObserve a full traffic cycle and revisit the tuning decision when freshness, engine mix, or account capacity changes.

Going by SKILL.md and its folder, Serpapi Performance Tuning needs credentials named SERPAPI_KEY. Our summary lists: Python 3; A credential in SERPAPI_KEY. Its frontmatter pre-approves these tools: Read, Glob, Grep, WebFetch, Write, Edit. Compatibility (from SKILL.md): Designed for Claude Code; production cache, output, or concurrency changes require owner approval and measured rollback criteria.
SKILL.md names 1 domain. As links in the text: serpapi.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Serpapi Performance Tuning is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1k tokens (SKILL.md is roughly 4.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
