Implement search rate limiting and fix cache memory leaks
Description
Summary
Stabilizes the search endpoint by introducing request throttling and resolving a persistent memory leak in the internal cache layer.
Why
Prevents service degradation during high-traffic periods and ensures long-term process stability by stopping heap growth in the caching service.
What changed
- Rate Limiting: Added middleware to
api/searchto enforce request quotas. - Memory Fix: Refactored the cache layer to properly evict expired entries, closing the observed leak.
- Configuration: New environment variables for search rate thresholds.
Test plan
- Suggested: Load test
/api/searchwith concurrent requests to verify 429 responses. - Suggested: Monitor heap usage over 1 hour under synthetic load to confirm leak resolution.
Risks / rollout
- Risk: Legitimate high-volume users might be throttled.
- Rollout: Monitor search error rates immediately after deployment.
Issue / ticket refs
- #442
Why this shape
- Evidence used: Commit subjects and user intent.
- Uncertainties: Specific rate limits were not in the commit messages; inferred from typical API patterns.
Title alternatives
- Stabilize search API: Rate limiting and cache leak fix
- Fix search memory leak and add request throttling
- Search API performance and stability improvements
Red flags / ask author
- Confirm the specific rate limit values (TPS/RPM) intended for the search endpoint.
Next steps
- Select your preferred title from the alternatives above.
- Verify the suggested test plan against your local environment.
- Paste the Markdown into your VCS provider.

About this skill
Writing PR descriptions is a chore that leads to lazy summaries like "misc fixes" or "update files," which slows down reviews and hides risks. This skill transforms raw git evidence into decision-useful documentation for busy maintainers. It eliminates the friction of manual drafting while ensuring every claim is grounded in actual diff data.
What it does
- Evidence-based drafting converts commit logs, diff hunks, or file lists into structured PR descriptions.
- Risk identification flags migrations, schema changes, and new dependencies found in the code.
- Test plan generation creates actionable verification steps based on the author's work or suggested manual checks.
- Title optimization provides multiple specific title alternatives to replace vague branch names.
- Integrity checking scans for secrets in the diff and ensures no ticket numbers or results are fabricated.
How it works
- Supply the
change_evidencesuch as agit logorgit diff --statalong with an optional intent statement. - The agent scans the files and logic changes to categorize the work by area and impact.
- It generates a structured draft including a summary, why the change matters, and a detailed "What Changed" list.
- Review the generated title alternatives and the pre-open checklist for final manual approval.
Frameworks & tools
This skill is language-agnostic and works with any Git-based workflow, including GitHub, GitLab, and Bitbucket. It interprets standard diff and log outputs.
Why this beats prompting it yourself
Generic prompts often hallucinate ticket numbers or guess the intent behind a change. This skill follows a strict "evidence-first" rule, refusing to invent data and explicitly labeling suggested versus confirmed test plans.
Use cases
- Drafting descriptions for large, complex diffs where manual summarizing is error-prone.
- Standardizing PR quality across a team using a consistent, decision-heavy template.
- Generating clear rollout and risk notes for DevOps and release managers.
Known limitations
Requires raw text input of diffs or commit logs as it cannot directly access private repositories. It will not auto-open or merge PRs.
