cordis-composition-reference

cordis-composition-reference is a skill for Claude Code, Codex from singula-ai/alego. It costs 59 tokens per session (640 once invoked), scanned A, a copy of cordis-composition-reference, MIT.

A reference for composing Cordis bundles, which are ordered collections of plugins and settings for this coding-agent harness.

In plain words
What is it for?
It is for writing or reviewing bundle patches and agent presets, and for finding available harness plugin packages.
Why use it?
It explains how to add, replace, group, disable, or isolate plugins without guessing the configuration format.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cordis-composition-reference 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 17d 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.

The opening of the file, as written. The whole thing — 30 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cordis composition reference

Reference material for bundle patches and preset plugin lists. Procedures live in cordis-plugin-development and editing-cordis-compositions.

Loader patch dialect

A profile composes an ordered list of patch layers over the bundle entry lists. Each patch is a mapping:

  • insert: [rows] appends rows; with an id naming an existing group: true row, the rows are appended inside that group's config list.
  • A patch with an id and no insert targets the existing row with that id. Supplied fields replace the row's fields; config is replaced wholesale, never deep-merged, so restate every field the row needs. A truthy name asserts the existing plugin name rather than renaming it.
  • Non-insert patches without a nonempty id, and targets that match no row, are warned about and skipped.

A row has id, name (the plugin package specifier; inserted relative paths are anchored beside their patch file), optional config, and optional disabled, inject, intercept, and isolate.

  • group: true with name: cordis:group makes config a nested entry list and allows patches to insert into it by id. cordis:include loads a literal YAML or JSON entry list from config.path.
  • disabled accepts a boolean, null, or a !!js expression evaluated against the Loader context at every mount decision. A disabled row omits required config unless group: true forces activation.
  • !!js scalars are Loader expressions, never !js. Inside config they are evaluated after the row's declared injections activate, against that plugin's context (ctx.<service>), so !!js alegoHomePath('sessions') and !!js "!ctx.get('profileContext')" are valid. Other row metadata stays literal.
  • isolate maps service names to true or a realm label; a preset plugin that provides a service isolates the provider and all consumers together. Scope controls contributions and event visibility; isolate controls service instances.

plugin_manager list_plugins reports each row's enabled flag and fiberPhase; set_plugin and set_bundle answer overridden when a higher-priority layer wins.

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.
