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 | $0.00110 | $0.03074 |
| Opus 5 | $0.00055 | $0.01537 |
| Sonnet 5 | $0.00022 | $0.00615 |
| Haiku 4.5 | $0.00011 | $0.00307 |
Grade B, and why
rembric-plugin-development 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 11d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- **`chmod 644` for files invoked as `node <path>`** (the +x bit isn't needed for `node x.mjs`). How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rembric plugin development
Authoritative specs: openspec/specs/{claude-code-plugin,codex-distribution,hermes-agent-plugin,opencode-plugin,pi-plugin,plugin-session-protocol}/. Archived decisions: openspec/changes/archive/.
Mandatory workflow
- OpenSpec change first. Run
/opsx:propose(or amend an existing change). Plugin work always touches ≥2 specs and ≥3 files. Skipping the change is the failure mode that produces drift. - Two release tracks:
server+ unifiedplugin(no cascade). release-please runs exactly two components, nonode-workspace/linked-versions/grouping.server(apps/server, package@rembric/server, tagserver-v*) builds the Docker image.plugin(apps/plugin— the WHOLE tree, noexclude-paths, package@rembric/plugin, tagplugin-v*) carries one unified version for all five clients; itsextra-filesupdate every client carrier in lock-step (.claude-plugin/{package,plugin}.json,.codex-plugin/{package,plugin}.json,.hermes-plugin/plugin.yaml,.opencode-plugin/plugin.tscomment,.pi-plugin/package.json). A change to ANY plugin file bumps the singlepluginversion — claude/codex/opencode/hermes/pi never diverge; the CHANGELOG (scoped by conventional commit) records what actually changed. Apluginrelease NEVER rebuilds the server image (publish-dockergates onserver_release_created), but it IS what publishes@rembric/pito npm (trusted-publishing OIDC, provenance, no long-lived token)..pi-plugin/has to live insideapps/plugin/for that: release-please attributes a release by the paths of the commits under the component'spath, so a client outside it would never cause a release and its carrier would only move when something unrelated did.release-please.ymlcarries aconcurrencyguard (cancel-in-progress: false) so a rapid second merge can't cancel tag-minting. The former six-component +node-workspacecascade was retired (changeunify-plugin-release-track) after its anchor-tag fragility produced phantom release PRs. Legacy per-client tags (claude-code-plugin-v*, …) stay in history, inert. - End-to-end against
pnpm run dev:docker:upbefore reporting done — see E2E discipline below. - Docs sweep:
README.md,docs/agents.md,apps/plugin/README.md, the in-pluginREADME.md,apps/plugin/CHANGELOG.md. New-client checklist in references/files-checklist.md.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rembric-plugin-development is a skill published in the GitHub repository susomejias/rembric (12 stars, last pushed 8d ago), licensed MIT. It adds 110 tokens to every session and 3,074 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
