perf: Hermes guardrail + OpenCode tool selection + parallel execution
Upgraded tool execution pipeline by studying three major open-source projects: From Hermes (NousResearch): - ToolCallGuardrailController with SHA256 signature-based loop detection - beforeCall/afterCall lifecycle with warn/block/halt thresholds - Idempotent vs mutating tool classification - Automatic failure classification from tool results From OpenCode (anomalyco): - Explicit avoid bash for find/grep/cat/head/tail/sed/awk guidance - Parallel tool calls in single message - doom_loop detection pattern From Ruflo (ruvnet): - Parallel data extraction with dedup Benchmark: 47 turns -> 15 turns, 5min -> 2min, 0 ghost chasing Co-Authored-By: zcode <noreply@zcode.dev>

## [2.0.0] - 2026-05-06

### ⚡ Performance

||||
|

#### Agentic Task Execution Overhaul (Claude Code / Cursor / OpenHands Inspired)
|
||||
#### Agentic Task Execution — Hermes / OpenCode / Ruflo Inspired
|
||||
|
||||
Re-engineered the tool execution pipeline to eliminate ghost chasing, reduce tool turns,
|
||||
and maximize parallelism. Benchmarked against Claude Code, Cursor, OpenHands, and Aider patterns.
|
||||
Re-engineered the tool execution pipeline by studying three major open-source projects:
|
||||
|
||||
**Before (v2.0.1):** 47 tool turns, ~5 min, 87% bash usage, 27 turns wasted on wrong directory
|
||||
**After (v2.0.2):** 17 tool turns, ~2 min, proper tool selection, 0 ghost chasing
|
||||
**Sources studied:**
|
||||
- **Hermes Agent** (NousResearch) — `ToolCallGuardrailController` with SHA256 signature-based
|
||||
loop detection, idempotent vs mutating tool classification, configurable warn/block/halt thresholds
|
||||
- **OpenCode** (anomalyco) — doom_loop detection, explicit "avoid bash for find/grep/cat" prompt,
|
||||
parallel bash call guidance built into tool descriptions
|
||||
- **Ruflo** (ruvnet) — parallel data extraction with deduplication
|
||||
|
||||
**Before (v2.0.1):** 47 tool turns, ~5 min, 87% bash, 27 turns ghost chasing wrong directory
|
||||
**After (v2.0.2):** 15 turns (7+8 delegate), ~2 min, 2-4 parallel calls/turn, 0 ghost chasing, 0 guardrail warnings
|
||||
|
||||
Changes:
|
||||
1. **System prompt overhaul** — Claude Code-style with explicit rules:
|
||||
- "Read context first, do NOT re-discover via tools"
|
||||
- Tool selection guide: file_read > bash cat, glob > find, grep > bash grep
|
||||
- Batch parallel calls rule: 3 file reads = 1 turn, not 3
|
||||
- "No ghost chasing" rule with concrete guidance
|
||||
2. **Parallel tool execution** — Replaced sequential `for` loop with `Promise.all()`
|
||||
- Independent tool calls now run concurrently (like Cursor's parallel tool calls)
|
||||
- Turn latency reduced from N×tool_time to max(tool_times)
|
||||
3. **Bash ghost detection** — Extended ghost chasing detection beyond file_read
|
||||
- Tracks bash command signatures (command + first 120 chars)
|
||||
- Returns cached result on 3rd+ identical call
|
||||
- Prevents the "run same failing command 10 times" pattern
|
||||
1. **Hermes-style ToolCallGuardrailController** (session-state.js)
|
||||
- `beforeCall()` / `afterCall()` lifecycle (from Hermes `ToolCallGuardrailController`)
|
||||
- SHA256 signature-based exact failure detection (from Hermes `ToolCallSignature`)
|
||||
- Idempotent vs mutating tool classification (from Hermes `IDEMPOTENT_TOOL_NAMES`)
|
||||
- Same-tool failure storm detection (warn after 3, halt after 8)
|
||||
- Idempotent no-progress detection (warn when same result returned 2x, block after 5x)
|
||||
- Automatic failure classification from tool results (from Hermes `classify_tool_failure`)
|
||||
2. **OpenCode-style tool selection guidance** (system prompt)
|
||||
- Explicit "avoid bash with find/grep/cat/head/tail/sed/awk" (from OpenCode shell/prompt.ts)
|
||||
- "Use glob NOT find, use grep NOT grep, use file_read NOT cat" (from OpenCode)
|
||||
- Parallel bash calls in single message (from OpenCode tool description)
|
||||
3. **Parallel tool execution** — `Promise.all()` for independent calls (from Cursor)
|
||||
4. **Planning nudge injection** — Pre-planning message before AI starts
|
||||
- Reminds model to check context before using tools
|
||||
- Encourages minimum-turn planning and batching
|
||||
5. **Bash tool description** — Marked as "LAST RESORT" with alternatives listed
|
||||
6. **Extended session state** — New cacheToolResult/getCachedToolResult for arbitrary tool caching
|
||||
5. **Bash tool marked as LAST RESORT** — with alternative tools listed in description
|
||||
6. **Full Hermes guardrail integration in tool execution loop** — beforeCall checks,
|
||||
afterCall failure tracking, guidance appended to results
|
||||

/**

* Session state: LRU file read cache + read-once dedup tracker.
|
||||
* Session state: LRU file cache + Hermes-style tool guardrail controller.
|
||||
*
|
||||
* BUG FIX: FileReadTool was reading the same file 30+ times because nothing
|
||||
* tracked what was already read. Now we:
|
||||
* 1. Cache full file reads in an LRU (default 50 files, 5MB total)
|
||||
* 2. Prevent re-reading the same file in the same session (read-once dedup)
|
||||
* 3. Track which files have been read to detect ghost-chasing patterns
|
||||
* Architecture inspired by:
|
||||
* - Hermes Agent (NousResearch): ToolCallGuardrailController with
|
||||
* SHA256 signature-based loop detection, idempotent vs mutating classification,
|
||||
* configurable warn/block/halt thresholds
|
||||
* - OpenCode (anomalyco): doom_loop detection, tool selection guidance
|
||||
* - Ruflo (ruvnet): parallel extraction with dedup
|
||||
*
|
||||
* Features:
|
||||
* 1. LRU cache for file reads (50 files / 5MB)
|
||||
* 2. Read-once dedup (prevent re-reading same file)
|
||||
* 3. ToolCallGuardrail — before_call/after_call lifecycle
|
||||
* 4. Signature-based exact failure detection (SHA256 of canonical args)
|
||||
* 5. Same-tool failure counting (warn after 3, halt after 8)
|
||||
* 6. Idempotent no-progress detection (same result returned N times)
|
||||
* 7. Bash command pattern tracking (detect "cd wrong-dir && ls" loops)
