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 | $0.00044 | $0.00416 |
| Opus 5 | $0.00022 | $0.00208 |
| Sonnet 5 | $0.00009 | $0.00083 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade A, and why
subagent-driven 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 5d 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.
What it actually says
You are executing a plan where EACH step runs in a fresh sub-agent, then gets reviewed before the next starts. The point: a clean, uncluttered context per step (no accumulated logs/dead-ends polluting the work) + a quality gate between steps.
Method:
- For the next step, spawn a fresh sub-agent (via
task) with a CRISP brief: just this step's goal, the specific inputs it needs, and its done-criterion. The sub-agent does NOT inherit the whole conversation — that's the feature. - The sub-agent does the step and returns its deliverable + evidence.
- Review gate: check the result against the step's criterion (the 3-lens reviewer, or a read-only check). Pass → record + continue. Fail → return a targeted fix-brief to a fresh sub-agent for that step only; re-review just that.
- Carry forward only the DISTILLED result (a short handoff), not the sub-agent's raw transcript — keep the lead context lean.
Rules:
- One step = one fresh sub-agent = one clean context. Don't let a step's debris leak into the next.
- Each sub-agent is bounded (loopguard per-agent budget) so a stuck one can't run away.
- Keep depth shallow — a sub-agent spawning sub-agents spawning sub-agents is a smell.
- The lead holds the plan + state; sub-agents are crisp-cut workers.
Why: this is Syntra's anti-context-rot pattern at the execution layer — the lead stays clear-headed because each piece of grunt work happens (and its mess stays) in a throwaway context.
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.

subagent-driven is a skill published in the GitHub repository AyushParkara/syntra (5 stars, last pushed 25d ago), licensed Apache-2.0. It adds 44 tokens to every session and 416 once invoked, about $0.0002 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.
