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 | $0.00026 | $0.00758 |
| Opus 5 | $0.00013 | $0.00379 |
| Sonnet 5 | $0.00005 | $0.00152 |
| Haiku 4.5 | $0.00003 | $0.00076 |
Grade D, and why
safety-guard scanned grade D with 2 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Escalated deletions (e.g., `sudo rm`). Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Recursive/forced deletions (e.g., `rm -rf /`, `rm -rf ~`, `Remove-Item -Recurse -Force` at root levels). How it starts
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CIEL ADAPTATION: Safety-Guard (Operational Failsafe)
This skill serves as the primary operational failsafe for CIEL's autonomous agents. It enforces the "Do No Harm" mandate by establishing strict operational boundaries, intercepting destructive actions, and allowing for granular, directory-level write locking.
Integration Context
Adapted from ~/.agents/skills/safety-guard/. This skill provides the behavioral ruleset that the Auditor sub-agent uses to evaluate run_shell_command requests and file modifications before execution.
Core Protection Modes
1. Careful Mode (Destructive Command Interception)
The Auditor MUST intercept and FAIL the execution of the following shell command patterns unless explicit human confirmation is provided via ask_user:
- Recursive/forced deletions (e.g.,
rm -rf /,rm -rf ~,Remove-Item -Recurse -Forceat root levels). - Destructive Git operations (e.g.,
git push --force,git reset --hard,git clean -fd). - Database annihilation (e.g.,
DROP TABLE,DROP DATABASE). - Broad permission changes (e.g.,
chmod 777 -R). - Escalated deletions (e.g.,
sudo rm). - Publishing artifacts (e.g.,
npm publish).
Action: Present the command's exact intent to the user, warn of the consequences, and suggest a safer alternative (e.g., git reset --soft or targeting a specific file instead of *).
2. Freeze Mode (Scope Confinement)
During complex, multi-agent refactoring or targeted feature implementations, orchestration can enforce a "Freeze Mode" limiting write access to a specific directory tree.
- Rule: If a Freeze Mode directory is declared (e.g.,
src/components/), the Auditor MUST reject anywrite_fileorreplaceactions attempting to modify files outside that directory. - Exception: Read operations (
read_file,grep_search,glob) are always universally permitted to maintain contextual awareness.
3. Guard Mode (Maximum Security)
Activates both Careful Mode and Freeze Mode simultaneously. Recommended for fully autonomous (unsupervised) loops.
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.

safety-guard is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 5d ago), licensed Apache-2.0. It adds 26 tokens to every session and 758 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
