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 | $0.00019 | $0.00527 |
| Opus 5 | $0.00010 | $0.00264 |
| Sonnet 5 | $0.00004 | $0.00105 |
| Haiku 4.5 | $0.00002 | $0.00053 |
Grade C, and why
repo-guard scanned grade C 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 10d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

100% identical to repo-guard — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Repo Guard Skill
Purpose
Proactively protect the repository from common mistakes and security issues.
Trigger Conditions
This skill activates automatically when:
- File write/edit operations are about to occur
- Bash commands are being executed
- Git operations are being performed
Protection Rules
1. Secret Detection
Detect and block commits containing:
- API keys and tokens
- Passwords and credentials
- Private keys
- Environment secrets
Patterns to watch:
- .env files
- *_KEY, *_SECRET, *_TOKEN patterns
- BEGIN PRIVATE KEY
- password=, passwd=, pwd=
- Bearer tokens
- AWS credentials
Action: Block and suggest using environment variables or secret managers.
2. Destructive Command Prevention
Block or require confirmation for:
rm -rf /
rm -rf *
rm -rf .
mkfs.*
dd if=
> /dev/sd*
chmod -R 777
Action: Block immediately with warning, suggest safer alternatives.
3. Main Branch Protection
Prevent direct modifications to:
- main branch
- master branch
- production branch
Action: Suggest creating feature branch first.
4. Large File Prevention
Warn about:
- Binary files > 10MB
- Generated files (node_modules, dist, build)
- Media files without LFS
Action: Warn and suggest .gitignore or Git LFS.
Response Behavior

- Edit tool calls
- Bash tool calls with git/rm/chmod
Cursor
Referenced in rules for file modification warnings.
Gemini CLI
Included in system prompt for command validation.
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.

repo-guard is a skill published in the GitHub repository Zenobia0000/ai-agentic-coding-template_unified (4 stars, last pushed 4mo ago), licensed MIT. It adds 19 tokens to every session and 527 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). It is 100% identical to repo-guard, differing in 0 lines, and is treated as a copy.
