Several published examples contained APIs that no longer exist, code that
does not run, or model versions that drifted from reality:
- agents/performance-optimizer.md used the web-vitals v3 API
(getCLS/getFID/getLCP/getFCP/getTTFB) and reported FID. web-vitals v4
renamed the imports to onCLS/onINP/onLCP/onFCP/onTTFB and FID was
replaced by INP (target < 200ms)
- rules/common/performance.md pinned stale model versions in the
model-selection guidance; refresh to the versions the repo itself uses
(agent.yaml pins claude-opus-4-6) and add the PowerShell variant for
MAX_THINKING_TOKENS next to the bash export
- skills/python-patterns/SKILL.md: both get_value examples referenced
default_value without declaring the parameter (NameError); add
default_value: Any = None to the EAFP and LBYL signatures
- skills/frontend-patterns/SKILL.md: the custom useQuery example rebuilt
refetch whenever callers passed inline fetchers/options, re-triggering
the effect after every state update (infinite fetch loop). Keep the
latest fetcher/options in refs so refetch stays referentially stable.
The PASS-labelled useMemo example mutated its input with in-place sort;
copy before sorting
- skills/coding-standards/SKILL.md repeated the same PASS-labelled
in-place-sort-in-useMemo example; same fix
- rules/typescript/security.md used a vendor-specific OPENAI_API_KEY in
generic guidance; switch to a neutral API_KEY
Every hand-maintained copy of the affected content is synced in the same
change: locale mirrors (ja-JP, ko-KR, pt-BR, tr, zh-CN, zh-TW - each only
where it carries the affected file) and the .agents/.kiro/.cursor harness
mirrors. Two structural divergences are left alone and noted here:
.kiro/steering/performance.md has no extended-thinking control list to
carry the PowerShell variant, and docs/zh-TW/rules/performance.md keeps an
older condensed thinking section without the budget-cap line.
rules/zh/performance.md is intentionally untouched - the rules/zh tree is
being retired in a separate change
Changes based on CodeRabbit review feedback:
1. Remove entire .cursor/ directory — it was an identical copy of the
main skills/commands/agents/rules, causing maintenance drift.
Users of Cursor can reference the canonical files directly.
2. Use explicit `is not None` checks instead of truthiness for
parsed['input'] and parsed['output']. Empty strings or empty
dicts are valid values that should be preserved.
Add complete .cursor/ directory with rules, agents, skills, commands,
and MCP config adapted for Cursor's format. This makes ecc-universal
a truly cross-IDE package supporting Claude Code, Cursor, and OpenCode.
- 27 rule files with YAML frontmatter (description, globs, alwaysApply)
- 13 agent files with full model IDs and readonly flags
- 30 skill directories (identical Agent Skills standard, no translation)
- 31 command files (5 multi-* stubbed for missing codeagent-wrapper)
- MCP config with Cursor env interpolation syntax
- README.md and MIGRATION.md documentation
- install.sh --target cursor flag for project-scoped installation
- package.json updated with .cursor/ in files and cursor keywords
