Previously, Claude Code's .mcp.json would silently override OpenCode user
config when MCP server names collided. This was unexpected behavior since
users expect their explicit OpenCode configuration to take precedence.
Changes:
1. Swapped merge order: Claude Code .mcp.json is now merged BEFORE user
config, so user config wins on collision
2. Added warning log when user config overrides a Claude Code MCP server:
'warning: MCP server X from user config overrides Claude Code .mcp.json'
3. Added comprehensive tests for collision scenarios
Fixes#2946
Previously, Prometheus always used params.currentModel (UI-selected model)
when no explicit configuration existed. This bypassed the intended fallback
chain (claude-opus-4-6 → gpt-5.4 → glm-5 → gemini-3.1-pro).
Now, the UI-selected model is only used if it matches one of the models
in Prometheus's fallback chain. Otherwise, the fallback chain resolution
takes over and finds an available model.
Fixes#2986
Static slash-command discovery runs before agent registration, so /start-work regressed to Sisyphus even though config-time wiring still needed Atlas-aware fallback. Split builtin command resolution so discovery stays Atlas-first while command config remains availability-aware.

- fix(context-limit): check modelContextLimitsCache for all Anthropic
models, not just GA-model set; user config/cache wins over 200K default
(fixes#2836)
- fix(agent-key-remapper): preserve config key aliases alongside display
names so `opencode run --agent sisyphus` resolves correctly
(fixes#2858)
- fix(tool-config): respect host permission.skill=deny by disabling
skill/skill_mcp tools when host denies them (fixes#2873)
- test: update context-limit and agent-key-remapper tests to match new
behavior
Inject an explicit `order` field (1-4) into the four core agents
(Sisyphus, Hephaestus, Prometheus, Atlas) via reorderAgentsByPriority().
This pre-empts OpenCode's alphabetical agent sorting so the intended
Tab cycle order is preserved once OpenCode merges order field support
(anomalyco/opencode#19127).

Reuse the current session's selected model during config-time agent rebuilds when config.model is missing, so desktop sessions do not snap back to the default model after each send.

The spread order in applyToolConfig was incorrect - omo's external_directory: 'allow'
was placed BEFORE the config.permission spread, allowing opencode's default 'ask' to
overwrite it. This caused write/edit tools to hang on headless opencode serve sessions
(no TUI to approve permission prompts).
Move omo's permission overrides AFTER the base config spread so they always win.
Fixes write/edit tool hangs when running opencode serve headlessly.
The default_builder_enabled config defaults to false, which removes
the default OpenCode Build agent on OMO install. This forces users
into the full OMO orchestration for every task, including simple ones
where the lightweight Build agent would be more appropriate.
Changed the default to true so the Build agent remains available
alongside Sisyphus. Users who prefer the previous behavior can set
default_builder_enabled: false in their config.
Fixes#2545
Keep install-time and runtime model tables in sync, stop OpenAI-only misrouting when OpenCode Go is present, and add valid OpenAI fallbacks for atlas, metis, and sisyphus-junior.

PR #2424 fixed the critical bug (passing client object instead of agent
summaries array), but only included user, project, and raw plugin agents.
This adds the two missing sources:
- OpenCode native config agents (params.config.agent)
- Plugin agents with migrateAgentConfig applied before summary extraction
Ensures Sisyphus has complete awareness of all registered agent sources.
Closes#2386

The DEFAULT_CATEGORIES ultrabrain model was updated from openai/gpt-5.3-codex
to openai/gpt-5.4 in a previous commit, but test expectations were not updated.
Updated test expectations in:
- src/plugin-handlers/config-handler.test.ts (lines 560, 620)
- src/agents/utils.test.ts (lines 1119, 1232, 1234, 1301, 1303, 1316, 1318)
Align runtime defaults, tests, docs, and generated artifacts with the newer GPT-5.4 baseline. Keep think-mode and prompt-routing expectations consistent after the model version bump.
Remove the hardcoded external_directory: "allow" default from
applyToolConfig(). This was silently overriding OpenCode's built-in
default of "ask" and any user-configured external_directory permission.
With this change, external_directory permission is fully controlled by
OpenCode's defaults and user configuration, as intended.
Fixes#1973Fixes#2194
When users have .md agent files in ~/.claude/agents/ with the same names
as builtin agents (e.g. sisyphus.md, hephaestus.md, atlas.md),
loadAgentsFromDir() hardcodes mode: "subagent" for all loaded agents.
Because the config assembly spreads userAgents after builtinAgents:
config.agent = {
...builtinAgents, // sisyphus: mode="primary"
...userAgents, // sisyphus: mode="subagent" ← overrides
}
this causes all primary agents to become subagents. The TUI filters out
subagents, so only non-plugin agents (like "docs") appear in the agent
selector.
Fix:
- Filter out user/project agents that share names with builtin agents
before spreading into config.agent (both sisyphus-enabled and fallback
branches)
- Respect frontmatter `mode` field in .md agent files instead of
hardcoding "subagent"
- Add `mode` to AgentFrontmatter type
