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 | $0.00000 | $0.00260 |
| Opus 5 | $0.00000 | $0.00130 |
| Sonnet 5 | $0.00000 | $0.00052 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
standard-back-end-typescript-clean-code-practices 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
Standard: Back-end TypeScript Clean Code Practices
This standard establishes clean code practices in TypeScript for back-end development to enhance maintainability and ensure consistent patterns across services. It covers logging best practices, error... :
- Avoid excessive logger.debug calls in production code and limit logging to essential logger.info statements. Use logger.info for important business events, logger.error for error handling, and add logger.debug manually only when debugging specific issues.
- Inject PackmindLogger as a constructor parameter with a default value using a variable or a string representing the class name.
- Instantiate use cases in adapters without passing the adapter's logger; use cases must create their own logger for proper origin tracking.
- Keep all import statements at the top of the file before any other code. Never use dynamic imports in the middle of the code unless absolutely necessary for code splitting or lazy loading.
- Use dedicated error types instead of generic Error instances to enable precise error handling and improve code maintainability. Create custom error classes that extend Error with descriptive names and context-specific information.

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.

standard-back-end-typescript-clean-code-practices is a cursor rule published in the GitHub repository PackmindHub/packmind (306 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 260 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
