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 | $0.03436 | $0.03436 |
| Opus 5.5 | $0.01374 | $0.01374 |
| Sonnet 5.5 | $0.00687 | $0.00687 |
| Haiku 4.5 | $0.00344 | $0.00344 |
Grade B, and why
corezoid-ai-plugin CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
Skills and commands use `${CLAUDE_PLUGIN_ROOT}` to reference files relative to the installed plugin root. This token is a host-side text substitution that Claude Code performs at skill-load time (see anthropics/claude-co How it starts

Repository Purpose
This is a Claude Code / Codex / Kiro plugin (@corezoid/corezoid-ai-plugin) that gives the AI the knowledge and tools to create, edit, and review Corezoid processes directly from the IDE. The repo ships:
- Static skills (
plugins/corezoid/skills/*/SKILL.md+ reference docs, JSON samples). - Plugin manifests for Claude Code, Codex, Kiro, and the agents marketplace, plus
POWER.mdfor the Kiro Powers registry. - A Go-based MCP server (
convctl) inplugins/corezoid/mcp-server/that exposes Corezoid operations as MCP tools. It has real tests (go test -race), golden tests for layout and lint, integration tests, and a release pipeline that builds signed multi-platform binaries.
Plugin Development Commands
# Publish a new version (triggers GitHub Actions on tag push)
git tag v1.x.x && git push origin v1.x.x
# Install the plugin locally for testing
npm install -g .
claude plugin install @corezoid/corezoid-ai-plugin
convctl MCP server (bundled in this plugin)
The MCP server is bundled as Go source at plugins/corezoid/mcp-server/. All operations are exposed as MCP tools — no separate installation required. The server starts automatically via .mcp.json, which runs mcp-server/run.sh.
To test the MCP server without Claude:
cd plugins/corezoid/mcp-server && npx @modelcontextprotocol/inspector go run . mcp-server
run.sh does not run the source next to it by default. It starts, in order: a locally built mcp-server/convctl (gitignored); else the release binary for the version in plugins/corezoid/.claude-plugin/plugin.json, downloaded from GitHub Releases and cached in ~/.cache/corezoid-mcp/<version>/; else go run . when that download fails. Between releases that version is the previous one, so a plugin session on main talks to the last released server, not to your changes. To exercise the source through the plugin, either build the binary (go build -o convctl . here — delete it afterwards, or it keeps shadowing the release binary) or start the client with COREZOID_MCP_DEV=1, which makes run.sh always go run .. Both need Go at the go.mod version, and a cold go run can overrun the client's 30-second startup timeout.
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.

corezoid-ai-plugin CLAUDE.md is an instructions file published in the GitHub repository corezoid/corezoid-ai-plugin (74 stars, last pushed yesterday), licensed MIT. It adds 3,436 tokens to every session, about $0.0137 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
