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 | $0.00000 | $0.01147 |
| Opus 5.5 | $0.00000 | $0.00459 |
| Sonnet 5.5 | $0.00000 | $0.00229 |
| Haiku 4.5 | $0.00000 | $0.00115 |
Grade A, and why
implementation-intermediate 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 1mo 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.
This is a copy
100% identical to implementation-intermediate — 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LEVEL 3 IMPLEMENTATION: BUILDING INTERMEDIATE FEATURES
TL;DR: This guide focuses on the systematic implementation of a planned and designed Level 3 feature. It emphasizes modular development, strict adherence to creative decisions and the style guide, integration with existing systems, and thorough feature-specific testing.

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.

implementation-intermediate is a cursor rule published in the GitHub repository alkoleft/mcp-bsl-platform-context (200 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,147 tokens. A static security scan graded it A with 0 findings. It is 100% identical to implementation-intermediate, differing in 0 lines, and is treated as a copy.
