Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.03586 |
| Opus 5.5 | $0.00012 | $0.01434 |
| Sonnet 5.5 | $0.00006 | $0.00717 |
| Haiku 4.5 | $0.00003 | $0.00359 |
Grade B, and why
coding-agent scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Model:** `gpt-5.2-codex` is the default (set in ~/.codex/config.toml) How it starts

Coding Agent (bash-first)
Use bash (with optional background mode) for all coding agent work. Simple and effective.
⚠️ PTY Mode Required!
Coding agents (Codex, Claude Code, Kiro, Pi) are interactive terminal applications that need a pseudo-terminal (PTY) to work correctly. Without PTY, you'll get broken output, missing colors, or the agent may hang.
Always use pty:true when running coding agents:
# ✅ Correct - with PTY
bash pty:true command:"codex exec 'Your prompt'"
# ❌ Wrong - no PTY, agent may break
bash command:"codex exec 'Your prompt'"
Bash Tool Parameters
| Parameter | Type | Description |
|---|---|---|
command |
string | The shell command to run |
pty |
boolean | Use for coding agents! Allocates a pseudo-terminal for interactive CLIs |
workdir |
string | Working directory (agent sees only this folder's context) |
background |
boolean | Run in background, returns sessionId for monitoring |
timeout |
number | Timeout in seconds (kills process on expiry) |
elevated |
boolean | Run on host instead of sandbox (if allowed) |
Process Tool Actions (for background sessions)
| Action | Description |
|---|---|
list |
List all running/recent sessions |
poll |
Check if session is still running |
log |
Get session output (with optional offset/limit) |
write |
Send raw data to stdin |
submit |
Send data + newline (like typing and pressing Enter) |
send-keys |
Send key tokens or hex bytes |
paste |
Paste text (with optional bracketed mode) |
kill |
Terminate the session |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.
- 1mo ago First seen · 416 lines · 30 tokens per session scan B 38d0749ae166
coding-agent is a skill published in the GitHub repository smallnest/goclaw (599 stars, last pushed 6mo ago), licensed MIT. It adds 30 tokens to every session and 3,586 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
