Summary

Introduces an autonomous performance research framework (/autoresearch-perf) to systematically discover and validate optimizations to RFA's syntax highlighting pipeline. This enables iterative, measured improvements through a structured loop of analysis, implementation, benchmarking, and decision-making.

Key Changes

  • .claude/skills/autoresearch-perf.md — Comprehensive skill definition documenting:

    • The iterative optimization loop (analyze → optimize → measure → keep/revert → repeat)
    • Benchmark infrastructure and key scenarios to monitor
    • Target files where highlighting performance lives
    • Decision criteria for keeping or reverting changes (≥2% improvement, <5% regression threshold)
    • Experiment logging format (append-only JSONL)
    • Rules for maintaining code quality and cache contracts
  • autoresearch-perf.md — State file tracking:

    • Current optimization objectives
    • Baseline metrics (to be populated on first run)
    • Target files with their roles and current optimizations
    • Experiment history
  • .gitignore — Added autoresearch-perf.jsonl to prevent committing experiment logs

Implementation Details

The framework enforces disciplined optimization practices:

  • One idea per iteration — Prevents confounding variables in measurements
  • Mandatory benchmarking — Every change is measured against baseline using existing rfa:benchmark-perf command
  • Focused scenarios — Highlights three key scenarios (diff-small, diff-large, diff-with-comments) while monitoring for regressions in review-page rendering
  • Immutable experiment log — JSONL format allows resuming across context resets while preserving full history
  • Clear decision criteria — Objective thresholds (≥2% improvement, <5% regression) remove ambiguity

This enables Claude to autonomously iterate on performance improvements while maintaining code quality, test coverage, and cache contract integrity.

Summary by CodeRabbit

  • Documentation

    • Added performance optimization workflow documentation for the syntax highlighting pipeline, establishing baseline metrics and improvement tracking procedures.
  • Chores

    • Updated configuration to exclude performance experiment logs.

Adds a Claude Code skill (`/autoresearch-perf`) inspired by pi-autoresearch
that runs an autonomous experiment loop to discover and validate performance
improvements to the syntax highlighting pipeline. Leverages the existing
`rfa:benchmark-perf` infrastructure for measurement.

- `.claude/skills/autoresearch-perf.md` — skill prompt with full loop protocol
- `autoresearch-perf.md` — objectives and experiment history (seed file)
- `.gitignore` — excludes the machine-generated `autoresearch-perf.jsonl` log

Warning

Rate limit exceeded

@fgilio has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 55 minutes and 15 seconds before requesting another review.

To keep reviews running without waiting, you can enable usage-based add-on for your organization. This allows additional reviews beyond the hourly cap. Account admins can enable it under billing.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.

Poem

A rabbit hops through code so bright,
Optimizing syntax, pixel-perfect light,
Benchmarks measured, experiments logged,
Performance dreams no longer bogged,
Hop by hop, we'll reach the peak! 🐰✨

P1 Badge Register this as a real skill command

This file is added as .claude/skills/autoresearch-perf.md, but the repo’s skill system is structured as .claude/skills/<name>/SKILL.md with front matter (and user_invocable: true for slash-invocable skills, as in .claude/skills/release/SKILL.md), so this markdown file will not be discovered as an invocable /autoresearch-perf workflow and the advertised command path in autoresearch-perf.md cannot be executed.

Useful? React with 👍 / 👎.

Moves .claude/skills/autoresearch-perf.md to
.claude/skills/autoresearch-perf/SKILL.md and adds frontmatter
(name, description, user_invocable: true) so the skill is
discoverable as an invocable /autoresearch-perf slash command,
matching the convention used by .claude/skills/release/SKILL.md.

96-99: Consider clarifying percentage sign convention for time improvements.

The criterion states "improved by ≥2%" but for time-based metrics, improvements (faster execution) result in negative percentage changes (e.g., -9.8% means 9.8% faster). While the JSONL example at line 115 demonstrates this convention, explicitly stating "≤-2% change" or "≥2% reduction" might reduce ambiguity.

In @.claude/skills/autoresearch-perf.md around lines 96 - 99, The rule text
under the "Keep if:" criterion currently reads "improved by ≥2%" which is
ambiguous for time-based metrics; change that phrase to explicitly state the

for time-based metrics)" or "improved by ≥2% (or ≥2% reduction for latency/time
metrics)"; update the same sentence that references "No scenario regressed by
more than 5%" if necessary to mirror the sign convention, and add a brief

- Around line 15-22: Add the missing Blade template entry for
resources/views/livewire/⚡diff-file.blade.php to the target files table in
autoresearch-perf.md so the HTML generation stage is represented; include it as
"Diff rendering template" (Role) and give an appropriate current optimization
note such as "server-side partial caching / minimal DOM updates" or "none" if
unoptimized, ensuring the new row mirrors the style of other rows (use backticks
for filename and match the three-column format used for other entries like
app/Services/SyntaxHighlightService.php and app/Actions/LoadFileDiffAction.php).

- Clarify time-metric sign convention in Keep/Revert criteria
  (faster execution = negative percent change), pointing to JSONL
  example.
- Add resources/views/livewire/⚡diff-file.blade.php row to the
  target files table in autoresearch-perf.md so it matches the
  pipeline coverage already listed in the SKILL.md target table.
