- Add _Dumper (CDumper if libyaml available, else Dumper) to core/io.py and use it in dump_yaml_str() for ~5x faster YAML serialization - Move no_runs_re and timed_out_re regex compilation to module level in rules_ci.py to avoid recompiling on every validate_recipe() call - Add tests for _Dumper type detection and module-level regex constants Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…comment Add pattern string assertions to test_no_runs_re_is_module_level_constant and test_timed_out_re_is_module_level_constant so a silent regex change cannot pass. Remove the section-divider comment that added no navigational value.
…rror A caller passing Dumper= in **kwargs would cause yaml.dump to raise TypeError for duplicate keyword argument. Pop it before forwarding to make the function safe against callers using dump_yaml_str as a transparent yaml.dump wrapper.

…mpile() to Module Level (#2200) ## Summary Two independent micro-performance fixes: (A) use the C-extension CDumper for YAML writes in `dump_yaml_str()` instead of the pure-Python dumper (~5× speedup), mirroring the existing CSafeLoader pattern for reads; and (B) hoist two `re.compile()` calls from inside `@semantic_rule` function bodies to module-level constants in `rules_ci.py`, since the patterns are static and those rules run on every `validate_recipe()` call (131 rules total). ## Requirements **Labels**: `recipe:implementation` ## Implementation Plan Plan file: `/home/talon/projects/autoskillit-runs/impl-20260507-150035-838422/.autoskillit/temp/make-plan/perf_add_cdumper_yaml_hoist_re_compile_plan_2026-05-07_150500.md` 🤖 Generated with [Claude Code](https://claude.com/claude-code) via AutoSkillit <!-- autoskillit:pipeline-signature steps=prepare_pr,run_arch_lenses,compose_pr,annotate_pr_diff,review_pr --> ## Token Usage Summary | Step | Model | count | uncached | output | cache_read | peak_ctx | turns | cache_write | time | |------|-------|-------|----------|--------|------------|----------|-------|-------------|------| | plan | claude-sonnet-4-6 | 1 | 125 | 7.8k | 497.3k | 55.9k | 46 | 46.9k | 2m 54s | | verify | claude-sonnet-4-6 | 1 | 84 | 7.8k | 422.2k | 61.8k | 29 | 49.0k | 2m 26s | | implement* | MiniMax-M2.7-highspeed | 1 | 384.5k | 5.8k | 645.0k | 70.6k | 52 | 51.9k | 2m 18s | | fix | claude-sonnet-4-6 | 1 | 150 | 5.5k | 680.1k | 50.5k | 45 | 37.6k | 8m 44s | | prepare_pr* | MiniMax-M2.7-highspeed | 1 | 101.7k | 5.2k | 329.9k | 35.1k | 25 | 22.7k | 1m 58s | | compose_pr* | MiniMax-M2.7-highspeed | 1 | 66.7k | 1.4k | 265.1k | 29.8k | 18 | 15.1k | 47s | | **Total** | | | 553.3k | 33.5k | 2.8M | 70.6k | | 223.1k | 19m 8s | \* *Step used a non-Anthropic provider; caching behavior may differ.* ## Token Efficiency | Step | LoC Changed | cache_read/LoC | cache_write/LoC | output/LoC | |------|-------------|----------------|-----------------|------------| | plan | 0 | — | — | — | | verify | 0 | — | — | — | | implement | 67 | 9626.8 | 774.1 | 86.1 | | fix | 2 | 340049.5 | 18780.5 | 2760.0 | | prepare_pr | 0 | — | — | — | | compose_pr | 0 | — | — | — | | **Total** | **69** | 41153.0 | 3233.7 | 485.9 | ## Model Usage Breakdown | Model | steps | uncached | output | cache_read | cache_write | time | |-------|-------|----------|--------|------------|-------------|------| | claude-sonnet-4-6 | 3 | 359 | 21.2k | 1.6M | 133.4k | 14m 5s | | MiniMax-M2.7-highspeed | 3 | 553.0k | 12.3k | 1.2M | 89.7k | 5m 3s | --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>
