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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00092 | $0.02907 |
| Opus 5 | $0.00046 | $0.01453 |
| Sonnet 5 | $0.00018 | $0.00581 |
| Haiku 4.5 | $0.00009 | $0.00291 |
Grade A, and why
setup-new-acpx-key scanned grade A 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 9d 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
`subprocess.Popen(env={**os.environ, **spec.env})` in How it starts
The opening of the file, as written. The whole thing — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Set Up a New ACPX Agent Key
Configures the credential for ONE ACPX agent_id so acp_spawn(agent_id=...)
launches the child CLI authenticated. The runtime never asks the LLM for a key:
each child reads its canonical env var, injected via
subprocess.Popen(env={**os.environ, **spec.env}) in
agent/acpx/runtime.py::AcpSession.spawn_child() (and _oneshot_send_turn).

Procedure
1. Verify the CLI is resolvable
The runtime calls windows_spawn.resolve_command(spec.command) at spawn
time and surfaces AGENT_NOT_FOUND if it cannot find the binary.
where ${cli_command} # Windows
which ${cli_command} # POSIX
If absent: install the CLI per its upstream docs, or pass
command_override and add it to the agent block in step 3.
2. Add the secret to data.keys (gitignored vault)
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.

setup-new-acpx-key is a skill published in the GitHub repository XAIHT/Tlamatini (16 stars, last pushed today), licensed MIT. It adds 92 tokens to every session and 2,907 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
