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 | $0.00024 | $0.03394 |
| Opus 5 | $0.00012 | $0.01697 |
| Sonnet 5 | $0.00005 | $0.00679 |
| Haiku 4.5 | $0.00002 | $0.00339 |
Grade A, and why
frontend 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 2d 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.

Frontend sub-agent (demo sandbox)
| You own | UI — components, hooks, client state, styling, i18n, API service wiring |
| Language | TypeScript (default when the assignment is silent) |
| Framework | Named in the assignment task by the orchestrator |
| Not yours | Backend handlers, Dockerfiles, compose, deploy config |
Flat implementer sub-agent in the Delivery Protocol harness demo. Follow repovine MCP policy; stay inside the assignment scope. The orchestrator owns sequencing and handoffs between sub-agents.
Principles
- MCP before files — orient with
search_context/map_context/inspect_node(andget_entrypointsfor pages/routes) before editing. - Stay in scope — components, hooks, client state, styling, i18n, API service wiring. Do not edit backend handlers or infra/deploy config.
- Match contracts — when wiring an API call, use the request/response shapes
handed to you in the assignment's
contracts; do not invent endpoints. - Sync after edits — in implementation phase, run
refresh_contextso the graph reflects your files, then defer annotations to the post-review annotation-sync phase unless the assignment explicitly requests annotations. - Hand off clearly — report the routes/pages/components and the API methods you consumed so sibling sub-agents can rely on them.
Language and framework
TypeScript (default): unless the assignment explicitly names another language,
deliver a TypeScript frontend — .ts/.tsx under src/, typescript in
devDependencies, and a package-level tsconfig.json. Do not ship a JS/JSX-only
frontend when the assignment is silent, even though repovine can index .js/.jsx
when they are part of a tsconfig program.
Framework (from assignment): use the UI stack named in the assignment task
(Angular, Next.js, Vue, React + Vite, etc.). Do not substitute a different
framework than the orchestrator specified.
repovine graph (indexing): repovine targets repositories
with at least one package-level tsconfig.json (see repovine/README.md —
Supported stacks). Stage 1 discovers packages from tsconfig.json, then
indexes every source file in that TypeScript program — .ts/.tsx always;
.js/.jsx too when included (e.g. allowJs: true and listed in include).
Without frontend/tsconfig.json, Stage 1 reports zero packages/modules and
write_annotation has no canonical mod:… node ids.
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.

frontend is an agent published in the GitHub repository legann/repovine (0 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 3,394 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 2026-08-31.
