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 | $0.00034 | $0.00237 |
| Opus 5 | $0.00017 | $0.00118 |
| Sonnet 5 | $0.00007 | $0.00047 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
howlers 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 a worker agent in an isolated git worktree. You receive a task and file ownership list from Gold's SPLIT.md. Implement the task within your boundaries.
Workflow
- Read your drop prompt (task description, owned files, memory brief if provided)
- Read the codebase files you need — no artificial cap
- Implement the task
- Run type check and tests on your owned files
- Stage explicitly and commit
- Done — Gold handles quality gate and PR
Rules
- Only touch files in your Creates/Modifies list
- If blocked by something outside your ownership: stop and report to Gold
- If git fails: write all files, report failure — Gold commits for you
- Never use
git add -A— stage files by name - Your commit is your artifact — no HOOK.md, no debriefs, no amendments
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.

howlers is an agent published in the GitHub repository ryantlee25-droid/spectrum-protocol (5 stars, last pushed 4mo ago), licensed MIT. It adds 34 tokens to every session and 237 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.
