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 | $0.00013 | $0.02770 |
| Opus 5 | $0.00006 | $0.01385 |
| Sonnet 5 | $0.00003 | $0.00554 |
| Haiku 4.5 | $0.00001 | $0.00277 |
Grade A, and why
linking-and-sources 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.
How it starts
The opening of the file, as written. The whole thing — 392 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Linking & Sources
Internal Linking
Chapter Links
- Always use absolute paths from doc root for chapter links
- Format:
/series/<series-slug>/chapters/<nn>-<chapter-title> - Examples:
/series/php-basics/chapters/01-your-first-php-script/series/ai-ml-php-developers/chapters/02-setting-up-your-ai-development-environment
See [Chapter 5: Your First ML Model](/series/ai-ml-php-developers/chapters/05-your-first-machine-learning-model-linear-regression-in-php) for the implementation.
Series Index Links
- Link to series overview pages with absolute paths
- Format:
/series/<series-slug>/
Review the [PHP Basics series](/series/php-basics/) for foundational concepts.
Code Sample Links
From Chapter Markdown to Code Files
Use relative paths from the chapter file to the code directory:
::: info Code Examples
Complete, runnable examples are available in:
- [`verify-installation.php`](../code/chapter-02/verify-installation.php)
- [`test-phpml.php`](../code/chapter-02/test-phpml.php)
- [`test-rubixml.php`](../code/chapter-02/test-rubixml.php)
:::
Pattern: ../code/<chapter-folder>/<filename>
Inline code references:
The complete implementation is in [`linear-regression.php`](../code/chapter-05/linear-regression.php).
From README to Code Files
Within a code directory's README, use relative paths:
- `verify-installation.php` - Comprehensive environment check
- `test-phpml.php` - PHP-ML library demonstration
- `solutions/exercise-1.php` - Solution to Exercise 1
Or for subdirectories:
See [`solutions/spam-filter-complete.php`](solutions/spam-filter-complete.php) for the full implementation.
Cursor Rule References (MDC Format)
When documenting code files in Cursor rules, use the mdc: format with full paths:
For Chapter 2, reference these files:
- [verify-installation.php](mdc:docs/series/ai-ml-php-developers/code/chapter-02/verify-installation.php) - Environment verification
- [test-phpml.php](mdc:docs/series/ai-ml-php-developers/code/chapter-02/test-phpml.php) - PHP-ML demonstration
- [composer.json](mdc:docs/series/ai-ml-php-developers/code/chapter-02/composer.json) - Dependencies
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.

linking-and-sources is a cursor rule published in the GitHub repository dalehurley/codewithphp (5 stars, last pushed 6mo ago), licensed MIT. It adds 13 tokens to every session and 2,770 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
