agentic-executor 1.0.2

High-performance execution layer for AI agents — filesystem, multi-language code analysis, process management

Agentic Executor

The execution layer for AI agents that need real hands

---

AI agents are powerful thinkers but poor actors. They call one tool, wait for a result, call another tool, wait again. Every step is a round-trip.

Agentic Executor gives the agent a Python interpreter and a set of high-performance commands. Instead of ten tool calls, it writes one script. Loops, conditionals, error handling — all in a single thought.

# One thought. Ten files. Zero round-trips.
python -m agentic_executor.cli --thought-stdin <<'EOF'
files = execute('search', {'pattern': '*.py'})
for f in files['data']['files']:
    result = execute('read', {'path': f, 'lines': 5})
    if result['success']:
        print(f"=== {f} ===")
        print('\n'.join(result['data']['lines']))
EOF

Install

pip install agentic-executor

No dependencies. Works immediately with Python's built-in ast for Python files.
For full multi-language support (20+ languages via tree-sitter):

pip install "agentic-executor[languages]"

---

Activate the /exec skill

After installing, deploy the /exec skill to your AI agent of choice:

exec-install                       # Claude Code  (default)
exec-install --agent cursor        # Cursor
exec-install --agent windsurf      # Windsurf
exec-install --agent kiro          # Kiro
exec-install --agent codex         # Codex
exec-install --agent copilot       # GitHub Copilot
exec-install --agent opencode      # OpenCode
exec-install --agent aider         # Aider
exec-install --agent claw          # OpenClaw
exec-install --agent hermes        # Hermes
exec-install --agent trae          # Trae
exec-install --agent droid         # Factory Droid
exec-install --agent all           # All at once

Check status at any time:

exec-install --list

---

How it works

Everything goes through one function: execute(command, args).

The agent writes Python code that calls execute(). That code runs locally, with full Python logic — loops, conditions, error handling, chaining results between steps.

# Standard return format — every command
{
    "success": bool,
    "data":    Any,       # command result
    "error":   str|None   # message if failed
}

Always check result['success'] before reading result['data'].

Commands

Filesystem

execute('read',    {'path': 'file.txt'})                                   # first 200 lines (default)
execute('read',    {'path': 'file.txt', 'full': True})                    # full file, no limit
execute('read',    {'path': 'file.txt', 'lines': 20})                     # first N lines
execute('read',    {'path': 'file.txt', 'start': 10, 'end': 30})          # range
execute('write',   {'path': 'out.txt', 'content': 'hello'})
execute('write',   {'path': 'log.txt', 'content': 'x\n', 'mode': 'a'})  # append
execute('replace', {'path': 'f.py', 'line': 42, 'new': '    # fixed'})   # line mode
execute('replace', {'path': 'f.py', 'old': 'foo()', 'new': 'bar()'})     # text mode
execute('copy',    {'src': 'a.txt', 'dst': 'b.txt'})
execute('move',    {'src': 'old.txt', 'dst': 'new.txt'})
execute('delete',  {'path': 'file.txt'})
execute('mkdir',   {'path': 'new/dir'})
execute('ls',      {'path': '.'})

Search

execute('search', {'pattern': '*.py', 'path': '.', 'recursive': True})
# → {"files": ["src/main.py", ...]}

execute('grep', {'pattern': 'TODO:', 'file_pattern': '*.py', 'path': '.'})
# → {"matches": [{"file": str, "line": int, "text": str}, ...]}

execute('info', {'path': 'file.txt'})
# → {"exists": bool, "type": "file"|"dir", "size": int, "modified": float}

Codebase intelligence

# Scan — supports Python, JS, TS, Go, Rust, Java, C, C++, Ruby, C#, Kotlin, Scala, PHP, Swift, Lua...
execute('scan_codebase', {'path': '.'})
# Writes cache to .agentic_executor/metadata.json

execute('get_metadata', {'type': 'summary'})
# → total files, functions, classes, imports

execute('get_metadata', {'type': 'structure'})
# → per-file: functions (name, line), classes, imports

execute('get_metadata', {'type': 'imports'})
# → import graph: who imports whom (bidirectional)

execute('get_metadata', {'type': 'all', 'filter': {'file': 'src/main.py'}})
# → single-file detail

Process

execute('run', {'cmd': 'pytest tests/', 'timeout': 60})
# → {"stdout": str, "stderr": str, "returncode": int}

Usage patterns

Batch operations

python -m agentic_executor.cli --thought-stdin <<'EOF'
files = execute('search', {'pattern': 'test_*.py'})

for f in files['data']['files']:
    result = execute('read', {'path': f, 'lines': 3})
    if result['success']:
        print(f"--- {f} ---")
        for line in result['data']['lines']:
            print(line)
EOF

Metadata-driven analysis

python -m agentic_executor.cli --thought-stdin <<'EOF'
execute('scan_codebase', {'path': '.'})
meta = execute('get_metadata', {'type': 'structure'})

# Find the most complex files
by_size = sorted(
    ((path, len(data['functions'])) for path, data in meta['data']['files'].items()),
    key=lambda x: x[1], reverse=True
)
for path, count in by_size[:5]:
    print(f"{count:3}  functions  {path}")
EOF

Conditional logic + cache

python -m agentic_executor.cli --thought-stdin <<'EOF'
info = execute('info', {'path': '.agentic_executor/metadata.json'})

if not info['data']['exists']:
    execute('scan_codebase', {'path': '.'})

meta = execute('get_metadata', {'type': 'summary'})
s = meta['data']['summary']
print(f"Files: {s['total_files']}  Functions: {s['total_functions']}  Classes: {s['total_classes']}")
EOF

Orchestrate external tools

python -m agentic_executor.cli --thought-stdin <<'EOF'
# Run any CLI tool and process its output with Python
result = execute('run', {'cmd': 'git log --oneline -10'})
if result['success']:
    commits = result['data']['stdout'].strip().split('\n')
    print(f"Last {len(commits)} commits:")
    for c in commits:
        print(f"  {c}")
EOF

Error handling

result = execute('read', {'path': 'file.txt'})

if result['success']:
    print(result['data']['content'])
else:
    print(f"Error: {result['error']}")
    # fallback logic

Multi-language support

Without tree-sitter (default): Python files via ast, other languages via regex patterns.
With pip install "agentic-executor[languages]": accurate parsing for 20+ languages.

Language	Extension	Parser
Python	.py	tree-sitter / ast
JavaScript	.js .jsx .mjs	tree-sitter / regex
TypeScript	.ts .tsx	tree-sitter / regex
Go	.go	tree-sitter / regex
Rust	.rs	tree-sitter / regex
Java	.java	tree-sitter / regex
C / C++	.c .h .cpp .hpp	tree-sitter / regex
Ruby	.rb	tree-sitter / regex
C#	.cs	tree-sitter / regex
Kotlin	.kt	tree-sitter / regex
Scala	.scala	tree-sitter / regex
PHP	.php	tree-sitter / regex
Swift	.swift	tree-sitter / regex
Lua	.lua	tree-sitter / regex
Elixir, Bash, R, Dart	...	regex

To install tree-sitter parsers separately:

exec-install --languages        # 9 essential languages
exec-install --full             # all 16

CLI reference

# Execute a thought inline
python -m agentic_executor.cli --thought "result = execute('ls', {'path': '.'}); print(result['data'])"

# Execute from stdin (recommended for multi-line code)
python -m agentic_executor.cli --thought-stdin <<'EOF'
# your Python code
EOF

# JSON output (for subprocess use)
python -m agentic_executor.cli --thought "..." --json-output

# Show available commands
python -m agentic_executor.cli --help-commands

Use --thought-stdin with heredoc for any script longer than one line or containing quotes. It avoids all shell escaping issues.

Tips

Raw strings for file content with escape sequences:

# Wrong — double escaping needed
content = 'def f():\n    print("hello")'

# Right — raw string, no escaping
content = r'''
def f():
    print("hello")
'''
execute('write', {'path': 'f.py', 'content': content})

Reading large files:

read always returns result['data']['content'] (str) — even when the file is truncated. Check truncated and use next_start to continue:

result = execute('read', {'path': 'big.py'})    # up to 200 lines, always 'content'
data = result['data']

if data.get('truncated'):
    # fetch the rest — next_start points to the first unread line
    rest = execute('read', {'path': 'big.py',
                            'start': data['next_start'],
                            'end':   data['total_lines']})
    full = data['content'] + '\n'.join(rest['data']['lines'])

# Or skip the loop entirely:
result = execute('read', {'path': 'big.py', 'full': True})

Scan before querying metadata:

execute('scan_codebase', {'path': '.'})   # always first
meta = execute('get_metadata', {'type': 'summary'})

Cache location: .agentic_executor/metadata.json — add to .gitignore.

When to use it

Use Agentic Executor when the task needs more than two steps or a loop.
For single reads or writes, use your agent's native tools directly — they're simpler.
