What a wild day.

GPT 5.3 Codex and Claude Opus 4.6 dropped on the same day. That's not a coincidence — that's the universe telling us we're living through something historic. Two frontier model providers, shipping simultaneously. Monumental.

And we adopted both the same day they shipped.

108 files changed. +4,666/-4,625 lines. A same-day sweep from one end of the codebase to the other. When the frontier moves, we move with it.

Hephaestus: The Legitimate Craftsman Evolves 🔨

New mindset: "KEEP GOING. SOLVE PROBLEMS."

Autonomous recovery got smarter. Hephaestus now tries 3 different approaches before bothering you. Stuck on a bug? He'll pivot, retry, adapt — all on his own. This is what autonomous execution should feel like.

Plus: provider-based activation. Got OpenAI, Copilot, or OpenCode connected? Hephaestus is ready. No exact model matching gymnastics required.

Custom Skills: First-Class Citizens

User-installed skills now get HIGH PRIORITY treatment in prompts. No more blending in with builtins — they're clearly separated, emphasized, and respected. Your custom workflows matter.

Safety First: Write Guard

New hook blocks agents from silently overwriting existing files. The write tool now checks before clobbering. Peace of mind.

What's New

Models

• Claude Opus 4.5 → 4.6, GPT 5.2 Codex → 5.3 Codex across 108 files
• Auto-migration: MODEL_VERSION_MAP upgrades your configs on load automatically
• Claude Opus 4.6 prioritized in anthropic fallback chains

Hephaestus

• "KEEP GOING. SOLVE PROBLEMS." mindset upgrade
• 3-approach-first recovery rule before escalating to user
• Provider-based gating: activates by connectivity, not exact model match

Skills

• Dynamic skill priority: user-installed skills emphasized with HIGH PRIORITY
• formatCustomSkillsBlock() extracted as shared DRY function

Safety & UX

• Write existing file guard: blocks overwrite of existing files
• Auto port selection: finds next available when 4096 is busy
• look_at image_data support: paste/clipboard images now work

Task System

• Task global storage with ULTRAWORK_TASK_LIST_ID support

Fixes

• Atlas continuation guard: stops infinite retry loops
• Compaction model-agnostic: removed hardcoded Claude model prefix
• Sisyphus-Junior: uses category model instead of UI-selected model
• Plan agent: dynamic categories/skills (not hardcoded)
• Schema sync: Zod schemas aligned
• Regex special chars escaped in pattern matcher
• Disabled tools actually enforced now
• Glob/Grep uses process.cwd() correctly
• Background agent abort handled gracefully
• Custom skills env var restoration fixed
• Provider cache handles both string[] and object[] formats
• LSP Windows: uses Node.js child_process (avoid Bun segfault)
• Boulder state agent tracking fixed
• Model availability honors connected providers
• Auto-update uses correct config dir
• Duplicate fallback entries cleaned

Refactoring

• Dead code removal: ollama-ndjson-parser.ts, plugin-state.ts, unused types
• Schema build: z.toJSONSchema → zodToJsonSchema
• formatCustomSkillsBlock DRY extraction

Docs

• AGENTS.md regenerated across all directories
• Config/feature docs updated

This is what shipping looks like when the frontier moves. Two models, one day, immediate adoption.
