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 | $0.00046 | $0.00233 |
| Opus 5.5 | $0.00018 | $0.00093 |
| Sonnet 5.5 | $0.00009 | $0.00047 |
| Haiku 4.5 | $0.00005 | $0.00023 |
Grade B, and why
soul-guard 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 2mo 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.

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

What it actually says
Soul Guard
Detects prompt injection backdoors in agent identity files. SOUL.md files tell agents who they are — if one gets tampered with ("ignore previous instructions", "you are now..."), Soul Guard catches it before it affects the agent.
Runs as a startup check (once before the agent loads its identity) or a background watcher (re-checks on file change). Alerts on any injection pattern or unauthorized modification.
When to use
- Any agent that loads its identity from a SOUL.md or similar identity file
- Shared agent deployments where the identity file could be written by untrusted parties
- Any agent that needs to assert its own identity hasn't been silently overwritten

What ships with it
1 file 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.

soul-guard is a skill published in the GitHub repository Parad0x-Labs/openclaw-skills (23 stars, last pushed 17d ago), licensed MIT. It adds 46 tokens to every session and 233 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (instruction-override phrasing). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

brain-save
Create and manage governed memories by capturing one fact, decision, pattern, or convention, or by retiring an outdated memory. This is side-effecting and never auto-fires. Use when preserving a durable fact without a full recompile or changing a memory's lifecycle. Trigger with "/brain-save".
brain
Search and analyze governed notes, decisions, runbooks, and conventions, returning a qmd:// citation for every supported claim. Use when checking what the brain has captured about architecture, infrastructure, decisions, or operating practices. Trigger with "/brain", "ask the brain", or "check my knowledge base".
