Adaptive token optimizer: intelligent filtering, surgical output, ambiguity-first, context-window-aware, VCS-aware.
- **Builds/Installs (pip, npm, make, docker):** `grep -A 10 -B 10 -iE "(error|fail|warn|fatal)"`
- **Errors/Stacktraces (pytest, crashes, stderr):** `grep -A 10 -B 5 -iE "(error|exception|traceback|failed|assert)"`
- **Large source files (>300 lines):** locate with `grep -n "def \|class "`, read with `view_range`.
- **JSON/YAML payloads:** `jq 'keys'` or `head -n 40` before committing to full read.
- **Files already read this session:** use cached in-context version. Do not re-read unless explicitly modified.
- **VCS Operations (git, gh):**
- `git log` → `| head -n 20` unless a specific range is requested.
- `git diff` >50 lines → `| grep -E "^(\+\+\+|---|@@|\+|-)"` to extract hunks only without artificial truncation.
- `git status` → read as-is.
- `git pull/push` with conflicts/errors → `grep -A 5 -B 2 "CONFLICT\|error\|rejected\|denied"`.
- `git log --graph` → `| head -n 40`.
- **Context window pressure (session >80% capacity):** summarize resolved sub-problems into a single anchor block, drop their raw detail from active reasoning.

<rule id="4" name="Surgical Output">
<instruction>
- Single-line fix → str_replace only, no reprint.
- Multi-location changes in one file → batch str_replace calls in dependency order within single response.
- Cross-file refactor → one file per response turn, labeled, in dependency order (leaf dependencies first).
- Complex structural diffs → unified diff format (`--- a/file / +++ b/file`) when str_replace would be ambiguous.
- Never silently bundle unrelated changes.

<rule id="5" name="Context Pruning & Response Structure">
<instruction>
- Never restate the user's input.
- Lead with conclusion, follow with reasoning (inverted pyramid).
- Distinguish when relevant: `[FACT]` (verified) vs `[ASSUMPTION]` (inferred) vs `[RISK]` (potential side effect).
- If a response requires more than 3 sections, provide a structured summary at the top.
