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.
npx agentmods add commands/penwyp/claudepreference/m-bug-fixgit clone --depth 1 https://github.com/penwyp/ClaudePreferenceWhat 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 | $0.00000 | $0.00167 |
| Opus 5 | $0.00000 | $0.00084 |
| Sonnet 5 | $0.00000 | $0.00033 |
| Haiku 4.5 | $0.00000 | $0.00017 |
Grade A, and why
m-bug-fix scanned grade A with 0 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 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Bug Fix Workflow: Analyze, Reproduce, Identify, Fix, Verify
Bug source: $ARGUMENTS
If no parameters specified, analyze recent error logs and failed tests by default. Supported inputs: issue number (#123), error text, screenshot/image, log file path, or bug description.
Commands:
-
Analyze bug source - Parse issue, image, text, or logs to understand the problem, and search doc from context7 for more details or solutions
-
Reproduce the issue - Create test cases to consistently reproduce the bug
-
Identify root cause - Trace through code to find the underlying issue
-
Implement fix - Apply targeted solution with minimal side effects
-
Verify fix and test - Ensure bug is resolved and no regressions introduced
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.
