SonicJS is a TypeScript-first headless content-management system that exposes content through REST APIs and an administrative interface, running on Cloudflare Workers or other SQLite-compatible environments. It is for developers building applications that manage and publish structured content, with storage through technologies such as D1 and R2. Catalogue add-ons help coding agents create and work with SonicJS projects and content.

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 | $0.02447 | $0.02447 |
| Opus 5.5 | $0.00979 | $0.00979 |
| Sonnet 5.5 | $0.00489 | $0.00489 |
| Haiku 4.5 | $0.00245 | $0.00245 |
Grade A, and why
sonicjs AGENTS.md 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 2mo 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SonicJS Agent Guidelines
These instructions mirror the workflow Claude Code already follows in Conductor so every coding agent behaves consistently.
Token-Efficient Tooling (use FIRST, before grep/Read sprees)
This repo is indexed by codegraph (684 files, 5693 nodes). Use it as the default code-lookup tool. Hook also rewrites shell commands via rtk for 60-90% bash savings. Default response mode is caveman for terse output.
Decision tree — code exploration
| Intent | Tool | Why |
|---|---|---|
| "How does X work / where does X live / trace flow X→Y" | mcp__codegraph__codegraph_explore |
ONE call returns verbatim source grouped by file. Replaces many Read/Grep. |
| "Just the location of symbol named X" | mcp__codegraph__codegraph_search |
Cheapest — name + path only. |
| "What calls this / what does this call / blast radius" | codegraph_callers / codegraph_callees / codegraph_impact |
Edges already indexed; grep can't follow dynamic dispatch. |
| Pinpoint known file edit | Read + Edit |
Codegraph not needed for known path. |
| Truly open-ended cross-cutting search | Agent w/ Explore or cavecrew-investigator |
Compressed output, protects main context. |
Rule: Before any 3+ Grep/Read combo for "where is X", call codegraph_explore first. Treat codegraph as a pre-built index — don't re-run searches it already answers.
rtk (Rust Token Killer)
- Bash commands auto-rewritten by hook — transparent, 0 overhead. No action needed.
rtk gainto audit savings;rtk discoverto find missed opportunities.- Don't bypass rtk with raw shell unless debugging.
caveman mode
- Active by default (full). Drops articles/filler. Code blocks, commits, security warnings stay normal.
- Toggle:
/caveman lite|full|ultra, off via "stop caveman".
Delegation — cavecrew subagents
Use when scope is bounded AND output would bloat main context:
cavecrew-investigator— read-only locator ("where is X / what calls Y / map this dir"). ~60% smaller tool result vs vanilla Explore.cavecrew-builder— surgical 1-2 file edit (typo, single-fn rewrite, mechanical rename). Refuses 3+ files.cavecrew-reviewer— diff/PR review, one line per finding.
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.

sonicjs AGENTS.md is an instructions file published in the GitHub repository SonicJs-Org/sonicjs (1,788 stars, last pushed yesterday), licensed MIT. It adds 2,447 tokens to every session, about $0.0098 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 2026-08-30.
