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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00119 | $0.02180 |
| Opus 5 | $0.00060 | $0.01090 |
| Sonnet 5 | $0.00024 | $0.00436 |
| Haiku 4.5 | $0.00012 | $0.00218 |
Grade C, and why
doc-package-contract scanned grade C with 1 finding 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 7d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- contract: references/package-contract-02-architecture.md#system-architecture --> How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Package Contract
Owns the shape of the package: which files exist, what each must contain, and what opens every one of them.
Iron Law
THE PACKAGE SHAPE IS FIXED — 8 directories, 23 files, every run. Content adapts; structure never.
A missing canonical file is indistinguishable from an incomplete run. An irrelevant topic is handled with a justified N/A at section level, never by deleting the file — because "we dropped that file, it did not apply" and "we ran out of time" read identically six months later.

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.

doc-package-contract is a skill published in the GitHub repository synaptiai/synapti-marketplace (6 stars, last pushed today), licensed Apache-2.0. It adds 119 tokens to every session and 2,180 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
