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 | $0.00381 |
| Opus 5 | $0.00000 | $0.00191 |
| Sonnet 5 | $0.00000 | $0.00076 |
| Haiku 4.5 | $0.00000 | $0.00038 |
Grade A, and why
agent-traits 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 yesterday.
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
Agent Traits
Synapse provides a set of traits to simplify managing various agent activities. These traits allow you to modify the PendingAgentTask during the agent lifecycle.
Example
For instance, to add output validation to your agent, you would first implement the HasOutputSchema interface, which introduces the resolveOutputSchema method for defining your validation rules. Then, use the ValidatesOutputSchema trait, and you're all set! To learn more about the ValidatesOutputSchema trait, see the ValidatesOutputSchema Trait Section.

use ValidatesOutputSchema;

}
public function resolveMemory(): Memory
{

}
public function resolveOutputSchema(): array

return [
SchemaRule::make([
'name' => 'answer',
'rules' => 'required|string',
'description' => 'Your final answer to the query.',
]),
];
}
}

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.

agent-traits is an agent published in the GitHub repository UseTheFork/synapse (50 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 381 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.

planner
Use this agent when the user needs a detailed implementation plan for a complex feature or task. Triggers on multi-step features, refactoring efforts, or tasks with unclear scope. Context: User starting a complex feature user: "I need to implement experiment comparison functionality" assistant: "I'll use the planner…
journey-synthesizer
Derives the run's journey map from the project profile and diff classification. This is the runtime replacement for v2's static journey catalog — there is no baked-in journey list. Every journey in the output traces to a real touched surface in the diff.
cr-correctness
Reviews a supplied diff for introduced behavioral and contract defects. Use only when dispatched by the code-review skill.
