coding-agent

coding-agent is a skill for Claude Code, Codex from swarmclawai/swarmclaw. It costs 99 tokens per session (943 once invoked), scanned A, original, MIT.

A way to delegate coding work to command-line coding agents such as Claude Code, Codex, Pi, and OpenCode. The agents can work in a project directory through shell commands.

In plain words
What is it for?
Building features or apps, reviewing pull requests, refactoring large codebases, exploring files, and running iterative coding tasks.
Why use it?
It lets a separate coding agent handle larger or repeated development tasks while you provide the assignment. The guidance also explains the different command and permission requirements for each agent.

  • high Excessive Agency · line 50
    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
  • high Tool Misuse · line 93
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coding-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Coding Agent

Delegate coding tasks to external coding agents via shell tools.

Agent Execution Modes

Claude Code (recommended)

Use --print --permission-mode bypassPermissions for non-interactive execution:

cd /path/to/project && claude --permission-mode bypassPermissions --print 'Your task here'

For background execution, use the shell tool's background mode.

Do NOT use PTY mode with Claude Code — --print mode keeps full tool access and avoids interactive confirmation dialogs.

Codex

Codex requires a git repository and PTY mode:

# Quick one-shot (auto-approves changes)
cd /path/to/project && codex exec --full-auto 'Build a dark mode toggle'

# Codex refuses to run outside a git directory. For scratch work:
SCRATCH=$(mktemp -d) && cd $SCRATCH && git init && codex exec "Your prompt"

Pi Coding Agent

# Install: npm install -g @mariozechner/pi-coding-agent
cd /path/to/project && pi 'Your task'

# Non-interactive mode
pi -p 'Summarize src/'

# Different provider/model
pi --provider openai --model gpt-4o-mini -p 'Your task'

OpenCode

cd /path/to/project && opencode run 'Your task'

PR Reviews

Clone to a temp folder or use git worktree — never review PRs in the SwarmClaw project directory:

# Clone to temp for safe review
REVIEW_DIR=$(mktemp -d)
git clone https://github.com/user/repo.git $REVIEW_DIR
cd $REVIEW_DIR && gh pr checkout 130
codex review --base origin/main

# Or use git worktree
git worktree add /tmp/pr-130-review pr-130-branch
cd /tmp/pr-130-review && codex review --base main

Parallel Issue Fixing

Use git worktrees to fix multiple issues in parallel:

# Create worktrees
git worktree add -b fix/issue-78 /tmp/issue-78 main
git worktree add -b fix/issue-99 /tmp/issue-99 main

# Launch agents (use background shell execution)
cd /tmp/issue-78 && codex --yolo 'Fix issue #78: <description>. Commit when done.'
cd /tmp/issue-99 && codex --yolo 'Fix issue #99: <description>. Commit when done.'

# Create PRs after
cd /tmp/issue-78 && git push -u origin fix/issue-78
gh pr create --repo user/repo --head fix/issue-78 --title "fix: ..." --body "..."

# Cleanup
git worktree remove /tmp/issue-78
git worktree remove /tmp/issue-99

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
