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 | $0.00129 | $0.02361 |
| Opus 5 | $0.00064 | $0.01180 |
| Sonnet 5 | $0.00026 | $0.00472 |
| Haiku 4.5 | $0.00013 | $0.00236 |
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 2d 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 (exec_command-first)
Use exec_command (with optional background mode) for all coding agent work. Use write_stdin to poll or continue a running session.
⚠️ PTY Mode Required!
Coding agents (Codex, Claude Code, 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 tty:true when running coding agents:
# ✅ Correct - with PTY
exec_command tty:true command:"codex exec 'Your prompt'"
# ❌ Wrong - no PTY, agent may break
exec_command command:"codex exec 'Your prompt'"
Host Tool Parameters
| Parameter | Type | Description |
|---|---|---|
command |
string | The shell command to run |
tty |
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_sec |
number | Timeout in seconds (kills process on expiry) |
Session Follow-Up Tools
| Tool | Description |
|---|---|
write_stdin |
Poll a session with chars:"" or send more input |
kill_session |
Terminate a background session |
Quick Start: One-Shot Tasks
For quick prompts/chats, create a temp git repo and run:
# Quick chat (Codex needs a git repo!)
SCRATCH=$(mktemp -d) && cd $SCRATCH && git init && codex exec "Your prompt here"
# Or in a real project - with PTY!
exec_command tty:true workdir:~/Projects/myproject command:"codex exec 'Add error handling to the API calls'"
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.

coding-agent is a skill published in the GitHub repository trpc-group/trpc-agent-go (1,759 stars, last pushed today), licensed Apache-2.0. It adds 129 tokens to every session and 2,361 once invoked, about $0.0006 per session on Opus 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.
Other skills, from other repositories
a2a-adapter
Use when building A2A Protocol agents, converting AI agents from any framework (LangChain, CrewAI, n8n, LangGraph, Ollama, or custom) into A2A-compatible servers, or working with the a2a-adapter Python SDK.
mistake-reflection
Use when you discover you made a mistake — caught by the user, by a tool result, by your own re-reading, or by a failed check. Appends a structured entry to docs/ai/ailearnings.md and re-reads recent entries to avoid repeats.
hephaestus-network
Use when the user types $hephaestus-network, /hep-network, or /agentlas-network, mentions @Hephaestus, or asks Agentlas to staff a durable goal from registered Local, owner Cloud, and public Hub agents or teams. The active host LLM staffs each turn; the exact roster remains goal-bound until explicit completion.
routing-card-authoring
Use whenever a build emits or repairs .agentlas/routing-card.json — the shared card contract for the single-agent builder, the team builder, and the packager. States what belongs in every field, which fields the hub can actually match on, and which fields silently break matching when a sentence leaks into them.
hephaestus-upload
Use when the user types $hephaestus-upload, /hep-upload, or /agentlas-upload, or asks to upload, publish, or list an Agentlas agent or team. Ask Cloud (private) vs Agentlas Hub (public) FIRST, then publish through the bundled Hephaestus gate.
agentlas-security-scan
Use when an agent folder must pass the Agentlas Cloud 2-stage security scan (static rules + BYOK LLM judgment) before private sync or public publish, or when asked to run/interpret hephaestus security scan.
