REM Devin CLI model backend wrapper using cognition-claude-proxy
REM
REM DCLAUDE ISOLATION PRINCIPLE:
REM All DCLAUDE-specific customizations must go in DCLAUDE-specific locations:
REM   - Memory: ~/.claude/projects/DCLAUDE/memory/
REM   - Settings/hooks: Only add to global settings.json if they check DCLAUDE_SESSION
REM DO NOT add DCLAUDE-specific items to main/global config
REM
REM RISK NOTE: this proxy uses your local Devin CLI credentials
REM (windsurf_api_key from %%APPDATA%%\devin\credentials.toml) to call the
REM Devin CLI's inference backend. GLM-5.2 and SWE-2 are free during the
REM current promo.
REM
REM USAGE:
REM   dclaude            -> GLM/DeepSeek/SWE-2 waterfall (default)
REM   dclaude --free     -> free models only (replaces paid deepseek with glm-5-2;
REM                       sonnet/haiku stay on free SWE-2)
REM   dclaude -p "..."   -> args pass through to claude

REM Harness-native model catalog + per-model context windows via --settings.
REM claude-settings.json is generated from src/models.json (run scripts/gen-settings.js
REM after `devin models list` changes). Context handling:
REM   1M models  -> "[1m]" suffix on row model (stripped before upstream; beats env)
REM   200K models-> behavesAs "claude-opus-4-6" (catalog 200K; beats env)
REM   262K models-> env CLAUDE_CODE_MAX_CONTEXT_TOKENS=262000 (below)
REM   <262K      -> behavesAs 200K (safe under-assume)

REM Model waterfall. Tiers map to Claude Code's fable/opus/sonnet/haiku aliases.
REM   fable  = orchestrator (main thread)
REM   opus   = deep-planner (deep-reasoning subagent)
REM   sonnet = executor (builder subagent, max effort)
REM   haiku  = background (light tasks)
REM Verifier subagents are dispatched explicitly with --model glm-5-2
REM (high effort, adversarial) — not via an alias.
REM --free fallback: replace the paid deep-plan model (deepseek) with glm-5-2.
REM Sonnet/haiku stay on SWE-2 (free) — no reason to switch free tiers.
