Native frontmatter fields

Features

How each feature converts to syllago's canonical format. See format conversion for what these statuses mean.

Fields

Native frontmatter or config fields this provider exposes. The first column is the provider's own field name; the canonical key column links to syllago's cross-provider equivalent.

Provider fieldConversionCanonical keySummary
allowed-toolsTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →tool_restrictionsallowed-tools frontmatter list (alias tools) restricts the tools a subagent can use, by Devin tool name (read, edit, write, grep, glob, exec, mcp__server__tool). ask_user_question is always withheld from subagents.
modelTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →model_selectionmodel frontmatter field overrides the subagent model; the default is the router-selected subagent model, not the parent's.
max-nestingDroppedConversion type: DroppedCan’t be meaningfully preserved. Removed from the output with a portability warning.Learn more →—max-nesting sets how deep a custom subagent may spawn child subagents. The canonical agent format has no equivalent, so syllago drops it on import.

Other features

Behaviors, conventions, and capabilities that aren't tied to a single named field — things like path-based activation, discovery rules, and lifecycle behavior.

FeatureConversionSummary
agent_scopesTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →Project scope at .devin/agents/ and .agents/agents/; user scope at ~/.config/devin/agents/ (Windows %APPDATA%\devin\agents\).
definition_formatTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →Markdown file with YAML frontmatter (name, description, model, allowed-tools, max-nesting) followed by the subagent's system prompt, as agents/<name>.md or agents/<name>/AGENT.md (AGENTS.md, agent.md, agents.md also accepted).
invocation_patternsTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →The agent picks a profile by its description when spawning a subagent; the user can ask for a profile by name. Subagents run in the foreground or background.
subagent_spawningTranslatedConversion type: TranslatedActively mapped to the target provider’s equivalent field during conversion.Learn more →max-nesting frontmatter field lets a custom subagent spawn its own subagents up to that depth; nesting is disabled by default.
Directory-form agent definitionsPreservedConversion type: PreservedSyntax survives conversion but the target provider may not interpret it.Learn more →An agent can be a directory agents/<name>/AGENT.md instead of a flat agents/<name>.md file; the directory name becomes the profile identifier.
