How do I install the Agentifind Benchmark skill?

Run npx skillmds@latest add avivk5498/agentifind-benchmark in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Agentifind Benchmark skill do?

Create a benchmark to measure CODEBASE.md effectiveness. Sets up hooks to run two parallel agents (one with guide, one without) and compare their efficiency. Requires /agentifind to be run first. It is listed under Coding & Dev Tools on SkillMD.

Is Agentifind Benchmark safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Agentifind Benchmark?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Agentifind Benchmark free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Agentifind Benchmark Setup

This skill creates a benchmark infrastructure to measure how effectively CODEBASE.md helps AI agents navigate your codebase.

Prerequisites

.claude/CODEBASE.md must exist (run /agentifind first)
.claude/codebase.json must exist

Procedure

Step 1: Verify Prerequisites

Check that required files exist:

test -f .claude/CODEBASE.md && test -f .claude/codebase.json && echo "Ready" || echo "Missing"

If files don't exist:

CODEBASE.md not found. Please run /agentifind first to generate the codebase guide, then run /agentifind-benchmark again.

Exit the skill if prerequisites are not met.

Step 2: Detect Repo Type and Tech Stack

Read .claude/codebase.json and check the repo_type field:

If repo_type is "terraform" (or other IaC types):

This is an infrastructure repository
Use the Infrastructure Benchmark Template (Step 6B)
Focus on resource navigation, blast radius, dependency tracing

If repo_type is missing or not an IaC type:

This is an application code repository
Use the Application Benchmark Template (Step 6A)
Identify:
- Primary language (Python, TypeScript, JavaScript, Go)
- Framework (FastAPI, Django, Flask, React, Next.js, Express, etc.)
- Key patterns (async jobs, API routes, components, services)

This information will be used to create relevant benchmark tasks.

Step 3: Create Hooks Directory

mkdir -p .claude/hooks

Step 4: Create Hook Scripts

Create these 5 executable scripts in .claude/hooks/:

4.1: `enforce-guide-restriction.sh`

This hook blocks AGENT_WITHOUT_GUIDE from reading CODEBASE.md and logs violations:

#!/bin/bash
#
# Enforce Guide Restriction Hook
# Blocks AGENT_WITHOUT_GUIDE from reading CODEBASE.md or .claude/ files
# Logs all violation attempts
#

INPUT=$(cat)

TOOL_NAME=$(echo "$INPUT" | jq -r '.tool_name // empty')
TOOL_INPUT=$(echo "$INPUT" | jq -c '.tool_input // {}')
AGENT_TRANSCRIPT=$(echo "$INPUT" | jq -r '.agent_transcript_path // empty')

LOG_DIR="$(pwd)"
VIOLATIONS_FILE="$LOG_DIR/benchmark_violations.jsonl"

# Only check Read tool
if [[ "$TOOL_NAME" != "Read" ]]; then
    echo '{"decision":"approve"}'
    exit 0
fi

# Only check subagents with transcript
if [[ -z "$AGENT_TRANSCRIPT" || ! -f "$AGENT_TRANSCRIPT" ]]; then
    echo '{"decision":"approve"}'
    exit 0
fi

# Extract agent identifier from transcript (try multiple patterns)
TRANSCRIPT_CONTENT=$(cat "$AGENT_TRANSCRIPT" 2>/dev/null)

# Try to find AGENT_WITHOUT_GUIDE in various message structures
IS_WITHOUT_GUIDE=false
if echo "$TRANSCRIPT_CONTENT" | grep -q "AGENT_WITHOUT_GUIDE"; then
    IS_WITHOUT_GUIDE=true
fi

if [[ "$IS_WITHOUT_GUIDE" != "true" ]]; then
    echo '{"decision":"approve"}'
    exit 0
fi

# Check for restricted file access
FILE_PATH=$(echo "$TOOL_INPUT" | jq -r '.file_path // empty')

if echo "$FILE_PATH" | grep -qiE "(CODEBASE\.md|\.claude/)"; then
    # Log the violation
    TIMESTAMP=$(date '+%Y-%m-%d %H:%M:%S')
    jq -n \
        --arg ts "$TIMESTAMP" \
        --arg agent "WITHOUT_GUIDE" \
        --arg file "$FILE_PATH" \
        --arg action "BLOCKED" \
        '{timestamp:$ts, agent:$agent, attempted_file:$file, action:$action, violation:true}' \
        >> "$VIOLATIONS_FILE"

    echo '{"decision":"block","reason":"BENCHMARK RULE: AGENT_WITHOUT_GUIDE cannot read CODEBASE.md or .claude/ files."}'
    exit 0

{
  "hooks": {
    "PreToolUse": [
      {
        "hooks": [
          {"type": "command", "command": ".claude/hooks/log-benchmark-tools.sh"}

        ]
      }
    ],
    "PostToolUse": [
      {
        "hooks": [
          {"type": "command", "command": ".claude/hooks/track-turns.sh"}
        ]
      }
    ]
  }
}

Step 6: Create Benchmark Tasks

Based on the repo type detected in Step 2, use the appropriate template.

Step 6A: Application Benchmark Template

Use this template when repo_type is NOT "terraform" or similar IaC types.

Create .claude/BENCHMARK_ENGINEERING.md with 7 tasks tailored to the detected tech stack.

Task Categories:

TASK-1 (⭐ Fundamental): Find a configuration value
TASK-2 (⭐ Fundamental): Locate a specific function/class
TASK-3 (⭐⭐ Intermediate): Trace a data flow
TASK-4 (⭐⭐⭐ Advanced): Add a new feature following existing patterns
TASK-5 (⭐⭐⭐ Advanced): Fix a bug with provided symptoms
TASK-6 (⭐⭐⭐⭐ Expert): Debug a race condition or performance issue
TASK-7 (⭐⭐⭐⭐⭐ Expert): Design a cross-cutting feature

Template:

# {Project Name} Engineering Benchmark

**Purpose:** Measure CODEBASE.md effectiveness on real engineering tasks.

---

## Orchestrator Instructions

You are running a benchmark to compare agent efficiency WITH vs WITHOUT the CODEBASE.md guide.

**IMPORTANT RULES:**
1. Run agents in FOREGROUND (do NOT use run_in_background)
2. Run both agents IN PARALLEL for the same task (single message, two Task calls)
3. Wait for both to complete before reporting results
4. Report token usage from the Task tool response if available
5. Track metrics from agent self-reports

---

## How to Run

### 1. Reset Logs
\`\`\`bash
.claude/hooks/reset-benchmark.sh
\`\`\`

### 2. Run Both Agents in Parallel (Foreground)

For each task, spawn BOTH subagents in a SINGLE message using two Task tool calls.
Do NOT use run_in_background - we need the full response including token usage.

\`\`\`
Task 1 (WITH_GUIDE):
- subagent_type: "general-purpose"
- run_in_background: false  # IMPORTANT: foreground for token tracking
- prompt: |
    AGENT_WITH_GUIDE: BENCHMARK

    You have access to .claude/CODEBASE.md - a navigation guide for this codebase.

    WORKFLOW:
    1. Read .claude/CODEBASE.md FIRST
    2. Use "Key Files" and "Architecture" sections to identify exactly where to look
    3. Go DIRECTLY to relevant files - don't search broadly
    4. Minimize tool calls - the guide tells you where things are

    TASK: [task description]

    DELIVERABLES:
    - Answer with specific file paths and line numbers
    - Confidence: HIGH/MEDIUM/LOW
    - METRICS: Read=[n] Grep=[n] Glob=[n] Total=[n] | Files: [list]

Task 2 (WITHOUT_GUIDE):
- subagent_type: "general-purpose"
- run_in_background: false  # IMPORTANT: foreground for token tracking
- prompt: |
    AGENT_WITHOUT_GUIDE: BENCHMARK

    RESTRICTION: Do NOT read .claude/CODEBASE.md or any .claude/ files.
    You must explore the codebase using only Grep, Glob, and Read on source files.

    TASK: [task description]

    DELIVERABLES:
    - Answer with specific file paths and line numbers
    - Confidence: HIGH/MEDIUM/LOW
    - METRICS: Read=[n] Grep=[n] Glob=[n] Total=[n] | Files: [list]
\`\`\`

### 3. Record Results

After both agents complete, fill in this comparison table:

| Metric | WITH_GUIDE | WITHOUT_GUIDE |
|--------|------------|---------------|
| Tool calls | | |
| Read | | |
| Grep | | |
| Glob | | |
| Confidence | | |
| Correct? | | |
| Tokens (if available) | | |

### 4. (Optional) Analyze Main Agent Activity
\`\`\`bash
.claude/hooks/analyze-benchmark.sh
\`\`\`

Note: The analysis script captures main agent tool calls. Subagent metrics come from self-reporting.

|----------|---|---|---|---|
| Completion | Failed | Partial | Minor issues | Correct |
| Efficiency | >50 calls | 30-50 | 15-30 | <15 |
| Blast Radius | Missed deps | Partial | Minor misses | Complete |

**Total: /9 per task, /63 overall**

Important: Each task must be specific to the actual infrastructure. Use information from:

codebase.json stats (resources, modules, providers)
codebase.json resources (real resource types and names)
codebase.json dependency_graph (real dependency chains)
codebase.json blast_radius (high-risk resources)

Step 7: Report Completion

Tell the user (adjust based on repo type):

For Application Repos:

Benchmark setup complete!

Repo Type: Application Code

Created:

.claude/hooks/ (5 scripts)

.claude/settings.json (hook configuration with PreToolUse + PostToolUse)

.claude/BENCHMARK_ENGINEERING.md (7 tasks)

To run the benchmark:

Reset: .claude/hooks/reset-benchmark.sh

For each task, spawn two parallel subagents (see BENCHMARK_ENGINEERING.md)

Analyze: .claude/hooks/analyze-benchmark.sh

The hooks will:

Block AGENT_WITHOUT_GUIDE from reading CODEBASE.md

Log violations when WITHOUT_GUIDE attempts to access restricted files

Log all tool calls for comparison

Track agent turns (API round-trips)

Metrics captured:

Tool call counts per agent

Tool breakdown (Read, Grep, Glob, etc.)

Violation attempts (blocked reads)

Agent turns (completed operations)

Files accessed by each agent

Expected result: 40-60% fewer tool calls with CODEBASE.md

For Infrastructure/Terraform Repos:

Benchmark setup complete!

Repo Type: Infrastructure (Terraform/IaC)

Created:

.claude/hooks/ (5 scripts)

.claude/settings.json (hook configuration with PreToolUse + PostToolUse)

.claude/BENCHMARK_INFRASTRUCTURE.md (7 infrastructure tasks)

To run the benchmark:

Reset: .claude/hooks/reset-benchmark.sh

For each task, spawn two parallel subagents (see BENCHMARK_INFRASTRUCTURE.md)

Analyze: .claude/hooks/analyze-benchmark.sh

Infrastructure-specific metrics:

Resource navigation efficiency

Blast radius identification accuracy

Dependency tracing completeness

Variable usage mapping

The hooks will:

Block AGENT_WITHOUT_GUIDE from reading CODEBASE.md

Log all .tf file accesses for comparison

Track how efficiently each agent finds resources/modules

Expected result: 40-60% fewer tool calls with CODEBASE.md, better blast radius accuracy

Notes

Tasks must reference real files and patterns from this specific codebase
Do not create generic tasks - analyze codebase.json to find actual components
Each task should have a clear expected answer based on the codebase
The benchmark measures navigation efficiency, not code quality
For IaC repos: Focus on resource discovery, dependency tracing, and blast radius assessment

Technical Limitations

Hooks don't run inside subagents: Claude Code hooks only execute in the main conversation context. Subagent tool calls are not captured by PreToolUse/PostToolUse hooks.

Workaround: Agents self-report their metrics at the end of each task. The prompt includes a METRICS template they must fill out.

What the hooks DO capture:

Main agent spawning subagents (Task tool calls)
Violations if WITHOUT_GUIDE tries to read .claude/ files (blocked by hook)

Token usage: Not directly available via hooks. To estimate:

Tool calls correlate with input/output tokens
Check API billing dashboard for actual usage
Or parse conversation transcripts in ~/.claude/projects/
