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 | $0.00028 | $0.01110 |
| Opus 5 | $0.00014 | $0.00555 |
| Sonnet 5 | $0.00006 | $0.00222 |
| Haiku 4.5 | $0.00003 | $0.00111 |
Grade A, and why
boolean-flag-responses 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 today.
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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Boolean Flag Diagnostic Protocol (1-Token Verification Gates)
Overview
When an autonomous pipeline or agent loop needs to evaluate a condition ("Does this pull request contain breaking API changes?" or "Does this SQL migration require a database lock?"), standard prompts generate 200 to 400 words of conversational justification.
In automated evaluation pipelines and CI/CD gates, downstream code only needs a binary decision (TRUE / FALSE). Generating narrative explanations wastes 99% of output tokens and requires fragile regex parsing.
The Boolean Flag Diagnostic Protocol constrains the model's output space strictly to 1-token booleans or discrete enums (TRUE, FALSE, PASS, FAIL), yielding deterministic, 50-millisecond evaluations.
Conversational Evaluation vs. 1-Token Binary Flag
┌─────────────────────────────────────────────────────────────┐
│ Diagnostic Output Comparison │
│ │
│ Conversational Evaluation (280 Tokens - High Latency): │
│ "After reviewing the pull request diff, I can confirm that │
│ there are no breaking changes. The modified functions │
│ maintain backward compatibility with existing clients..." │
│ ↳ 280 tokens, 3.2s latency, requires regex to parse │
│ │
│ 1-Token Boolean Directive (1 Token - Sub-second): │
│ FALSE │
│ ↳ 1 token, 0.05s latency, 100% deterministic parsing │

Pattern 1: The Breaking Change Detector Gate
Analyze the git diff below:
<diff>
[PASTE GIT DIFF]
</diff>
Question: Does this diff introduce any breaking API changes or remove existing exported functions?
Output Rule:
- Output strictly ONE word: `TRUE` (if breaking changes exist) or `FALSE` (if 100% backward compatible).
- Zero conversational commentary, zero punctuation.
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.

boolean-flag-responses is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 1,110 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 2026-09-05.
