Crate mars_schema 

Pure schema vocabulary, parsing, validation, and editing for Mars packages.

Re-exports

pub use harness::HarnessId;

Modules

agent

Agent definition reader.

claude

The Claude dialect: plugin and marketplace manifests, discovery, relocation and translation of Claude-shaped repositories into schema v1 items.

dependency

One [dependencies] or [local-dependencies] entry, as a package manifest or a consumer mars.toml writes it: its source, selectors and filter, and the rules that hold wherever it is read. The consumer’s configuration, a package’s manifest reading and mars add all read an entry through Entry::read, which holds every rule and says, by Strictness, which of them refuse and which only warn.

diagnostic

Stable diagnostics returned by schema operations.

dialect

Inbound dialect vocabulary for foreign definitions.

discover

Definition selection over a host-independent package tree, and the one bounded directory walk every convention scan shares (the binary’s bootstrap walk included).

edit

Canonical YAML emission for editors that splice bytes into authored frontmatter.

filter

Which of a package’s items a dependency entry selects: the authored agents, skills, exclude, only_skills, only_agents and rename keys, their consistency rule, and the FilterMode they resolve to.

frontmatter

git_url

harness

Stable harness identifiers and authored-name parsing.

harness_overrides

harness-overrides: the per-harness passthrough blocks of an Agent or skill.

inspect

inspect: what is in a repository, before anything is selected or converted.

item

Package item vocabulary.

links

The skill body-link rule: which relative links leave a skill’s payload and stop resolving once the skills are installed.

manifest

Package-manifest reading owned by the schema boundary.

markdown

Small Markdown syntax helpers shared by build and compiler paths.

mcp

Canonical MCP tool references in tools: / disallowed-tools: lists.

mcp_server

The authored MCP server definition: the vocabulary and the pure parse of one mcp/<name>/mcp.toml.

mcp_servers

The mcpServers entry: the one codec for the shape Claude’s .mcp.json declares and Cursor, Pi and a generated Claude/Codex plugin tree copy.

model_policy

Model-policy definition and validation shared by profiles and consumer config.

names

Names and relative coordinates the dependency vocabulary is built from: item names, source subpaths, and rename maps. Pure string handling; separators normalize to / on every host.

network

Shell network policy: the mode a profile, overlay, settings or CLI flag names, and the host grammar of its allow and deny sets.

normalize

normalize: turn a selection of a repository into schema v1 packages.

ordered

A JSON-shaped value that keeps mapping key order.

package

Versioned package metadata and manifest classification.

permission_set

One layer of an additive permission set: a plain list adds to lower layers, replace clears them.

plugin_metadata

Pure validation for Mars-generated plugin tree markers.

prepare

One-pass package classification, normalization, selection, and strict reading.

provider

Provider names, the hosts that supply skills Mars installs outside the dependency graph.

read

The serialized v1 reading shared by native and WASM callers.

selection

Item selection: which Agents, skills and package-level documents of a settled dependency graph a consumer installs.

skill

Skill definition reading.

tool_names

Mars tool-name grammar.

tool_natives

Explicit per-harness native tool names for Mars capabilities.

tool_policy

Canonical authored tool-policy values and frontmatter parsing.

tree

Host-independent package tree access.

upgrade

Pure legacy Mars definition and manifest upgrades to schema v1.

version

The two version grammars Mars reads and how a version is chosen among a repository’s tags.

visibility

Whether an effectful package item (a hook or an MCP server) crosses a package boundary.

Macros

string_newtype

Constants

VERSION

The schema crate version, kept in lockstep with the Mars CLI.
