+## Coding Task Breakdown
+
+1. Code exploration
+2. Planning/spec generation
+3. Code generation
+4. Formatting, linting, typecheck and other quality checks
+5. Review and find bugs
+6. Build or test or run the code
+
+## Model Rejection Criteria
+
+### `gpt_5.2` and `gpt_5.2_codex`
+
+- Too slow and expensive for the workhorse role
+- Not at all suggested for exploration or tool calls
+- Strictly for planning/spec gen and code gen
+
+### `opus_4.5`
+
+- Very buggy and looks for shortcuts in code gen
+- Can be a good critic and reviewer
+- Never use for code gen
+
+### `kimi_k2.5`
+
+- OK in all areas and fast
+- Never be primary for large code gen
+- Can be used for a second opinion
