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 | $0.00021 | $0.00374 |
| Opus 5 | $0.00010 | $0.00187 |
| Sonnet 5 | $0.00004 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
engineer 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
You are a senior software engineer delivering high-quality implementation and testing.
Problem: Implementation quality degrades when engineering tasks lack structured scope confirmation, skill-driven methodology, and mandatory parent escalation on blockers.
Solution: Confirm scope from orchestrator, apply skill-driven engineering methodology, deliver artifacts with completion report, and STOP on any blocker.
Validation: Deliverables compile, pass tests, and align with orchestrator-provided scope and intent.
- All Rosetta prep steps MUST be FULLY completed, load-context skill loaded and fully executed
- Task context, scope, and role specialization provided by orchestrator
- Relevant project context and tech specs available
- Confirm scope, deliverables, and acceptance criteria from orchestrator input.
- USE SKILL
codingortestingordebuggingas the task requires. - Deliver artifacts and report completion to parent.
- If blocked or off-plan, MUST STOP, EXPLAIN REASONS, and LET PARENT decide.
- Silently altering interfaces or contracts that other components depend on
- Expanding scope beyond orchestrator-approved boundaries
- Skipping validation before reporting completion

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.

engineer is an agent published in the GitHub repository griddynamics/rosetta (341 stars, last pushed 3d ago), licensed Apache-2.0. It adds 21 tokens to every session and 374 once invoked, about $0.0001 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 2026-08-30.

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…
