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 | $0.00083 | $0.00741 |
| Opus 5.5 | $0.00033 | $0.00296 |
| Sonnet 5.5 | $0.00017 | $0.00148 |
| Haiku 4.5 | $0.00008 | $0.00074 |
Grade A, and why
dedup-prior-art-check 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dedup / Prior-Art / Novelty Check
Before spending effort on a lead and again immediately before submitting a finding, prove the
vulnerability (and the specific composite chain) is not already known — so the squad never burns a
report on a duplicate. This operationalizes systematic-attacking Phase 1 and its pre-submit refresh
into a concrete, evidence-producing gate.
Source: corpus B §11 (Cyfrin Solodit — 49k+ aggregated real-world smart-contract findings, via
solodit-mcp when adopted) and the chrono-dedup plugin; corpus A elite-vs-average (narrow-and-deep
continuous prior-art discipline).
Impact class enabler: protects report acceptance rate; a duplicate/likely-duplicate verdict
routes a lead for differentiation. This gate does not itself kill or demote - campaign disposition,
and the single Phase-5 candidate-kill point, is owned by shared/modes/bounty.md.
Governing method: the dedup gate of systematic-attacking (Phase 1 + pre-submit).
Method
- Build the search key from the lead: root-cause class, affected contract/endpoint/component, protocol + version, and the specific chain shape (not just the vuln class).
- Query the prior-art surfaces via the
chrono-dedupplugin: program disclosure history (HackerOne/ Immunefi), GHSA/CVE/OSV, and — for web3 — the Solodit corpus (solodit-mcpif provisioned; else noteneeds_tooland use manual Solodit lookup). Search our ownchrono-vaultfor prior squad work on the target. - Classify:
novel/variant-of-known(cite the closest prior finding + what differs) /likely-duplicate/duplicate. Composite chains get a separate verdict — a chain of known primitives can still be a novel composition, and a novel-looking chain can be a known composite. - Return the novelty verdict with evidence; do not kill or demote - that is the campaign's call
(
shared/modes/bounty.md, Phase 5). An exact collision leaves the active queue but is preserved as an inner-link primitive for the chainer ('differentiate, don't veto'). Forvariant-of-known, document the delta that makes it independently submittable. - Refresh the check immediately before submission (new disclosures land daily); attach the dated query evidence to the report.
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.

dedup-prior-art-check is a skill published in the GitHub repository mtarcure/claude-vibe-squad (165 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 741 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-19.
