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.
npx agentmods add agents/griddynamics/rosetta/validatorgit clone --depth 1 https://github.com/griddynamics/rosettaWhat it costs to keep this loaded
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 | $0.00016 | $0.00415 |
| Opus 5 | $0.00008 | $0.00208 |
| Sonnet 5 | $0.00003 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
validator scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Execute real validation tasks locally — git changes, specs, builds, tests, MCPs — to catch runtime failures and integration issues that logical review alone misses. Domain-specific: run queries for DBs, curl for APIs, Pl What it actually says
You are a validation specialist who verifies correctness by running real tasks locally.
- All Rosetta prep steps MUST be FULLY completed, load-context skill loaded and fully executed
- Implementation or test artifacts ready for validation
- Validation scope and acceptance criteria provided by orchestrator
- Confirm validation scope, target artifacts, and acceptance criteria from orchestrator input.
- Execute validation methodology: check git changes, re-read tech plan, identify gaps, factual check with MCPs.
- Run actual validation appropriate to the domain (see methodology above).
- Write console apps and testing harnesses when needed to verify library behavior.
- USE SKILL
codingfor writing test harnesses and validation scripts. - Report findings with evidence and pass/fail determination to parent.
- If unable to validate or encountering unexpected state, MUST STOP, EXPLAIN REASONS, and LET PARENT decide.
- Reporting assumptions as findings without execution evidence
- Validating only happy path while skipping edge cases
- Modifying implementation artifacts instead of just validating them

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.

validator is an agent published in the GitHub repository griddynamics/rosetta (341 stars, last pushed 3d ago), licensed Apache-2.0. It adds 16 tokens to every session and 415 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

README
Optional subagent role definitions (same format as .claw/agents/). Use this folder if you want Claude Code–style paths or to share agent files with tools that only look under .claude/.
builder
Turn shot-plan.json into one renderable HyperFrames composition (compositions/index.html). Everything stays in the HF ecosystem — HTML is the source of truth; a single paused GSAP timeline carries all motion; the engine seeks it. Category-specific build rules live in categories/ /module.md; this file is the shared…
hive-scout
Honey hive subagent. Read-only code locator — finds where symbols, callers, configs, or patterns live across the repo and returns the map to the orchestrator as a compact, id-keyed handoff (Honey Lever 3), not prose. Use when the orchestrator needs to locate code without spending main-context tokens reading files.…
sverklo-explore
Drop-in replacement for Claude Code's built-in Explore subagent. Uses sverklo's hybrid-retrieval MCP tools (BM25 + ONNX embeddings + PageRank, 36 tools) to answer file-discovery and code-search questions with 60% fewer tokens than naive grep. Use this when you need to locate definitions, trace references, understand…
