Built-in agents (Sisyphus, Hephaestus, Atlas) now include explicit
identity section in their system prompts, matching custom agent behavior.
12 agent identity tests pass, 266 total pass, tsc clean.
Closes#2964
Tighten Background Result Collection instructions so the model waits
for explore/librarian results instead of duplicating their work and
delivering premature answers.
- Remove 'Continue working immediately' which models interpreted as
'do ALL work yourself, ignore agents'
- Clarify step 2: only do DIFFERENT independent work while waiting
- Add explicit step 3: end response when no other work remains
- Add 'not for files you already know' to explore section header
Fixes#2124, fixes#1967
Remove deep parallel delegation section from GPT-5.4 Sisyphus prompt since
it encouraged direct implementation over orchestration. Add zero-tolerance
category domain matching guide to all Sisyphus prompts with visual-engineering
examples. Rewrite visual-engineering category prompt with 4-phase mandatory
workflow (analyze design system, create if missing, build with system, verify)
targeting Gemini's tendency to skip foundational steps.
Non-Claude models skip planning and under-parallelize. Two new sections
injected only when model is not Claude:
- Plan Agent Dependency: multi-step tasks MUST consult Plan Agent first,
use session_id for follow-ups, ask aggressively when ambiguous
- Deep Parallel Delegation (rewrite): explicit '4 units = 4 agents'
pattern, each with clear GOAL + success criteria, all run_in_background
Sisyphus prompt instructed 'your next action is background_output' which
caused agents to repeatedly poll running tasks instead of ending their
response and waiting for the system notification.
- Replace 'STOP all other output' with 'end your response' (actionable)
- Add system-reminder notification mechanism explanation
- Add explicit 'Do NOT poll' prohibition
- Reduce background_cancel(all=true) mentions from 5x to 1x (Hard Blocks)
- Reduce Oracle collect obligation from 4x to 2x
- Remove motivational fluff ('blind spots', 'normal and expected')
Net: -2 lines, clearer mechanism, eliminates polling loop root cause.
GPT-5.x Codex models occasionally hallucinate malformed tool calls like:
assistant to=functions.XXX <garbled_unicode>json\n{...}
This is a model-level issue where the model outputs tool calls as text
instead of using the native tool calling mechanism. Add explicit prompt
instructions telling the model to use the tool call interface.
Related: #2190
Add buildDeepParallelSection() function that injects guidance for non-Claude
models on parallel deep agent delegation:
- Detect when model is non-Claude and 'deep' category is available
- Inject instructions to decompose tasks and delegate to deep agents in parallel
- Give goals, not step-by-step instructions to deep agents
- Update Sisyphus prompt builder to pass model and call new function
This helps GPT-based Sisyphus instances leverage deep agents more effectively
for complex implementation tasks.

Per reviewer feedback (code-yeongyu), keep the 'skill' tool as the main
tool and merge slashcommand functionality INTO it, rather than the reverse.
Changes:
- skill/tools.ts: Add command discovery (discoverCommandsSync) support;
handle both SKILL.md skills and .omo/commands/ slash commands in a single
tool; show combined listing in tool description
- skill/types.ts: Add 'commands' option to SkillLoadOptions
- skill/constants.ts: Update description to mention both skills and commands
- plugin/tool-registry.ts: Replace createSlashcommandTool with createSkillTool;
register tool as 'skill' instead of 'slashcommand'
- tools/index.ts: Export createSkillTool instead of createSlashcommandTool
- plugin/tool-execute-before.ts: Update tool name checks from 'slashcommand'
to 'skill'; update arg name from 'command' to 'name'
- agents/dynamic-agent-prompt-builder.ts: Categorize 'skill' tool as 'command'
- tools/skill-mcp/tools.ts: Update hint message to reference 'skill' tool
- hooks/auto-slash-command/executor.ts: Update error message
The slashcommand/ module files are kept (they provide shared utilities used
by the skill tool), but the slashcommand tool itself is no longer registered.
Convert all markdown tables in Sisyphus and dynamic-agent-prompt-builder
to plain bullet lists for cleaner prompt rendering.
Add explicit Oracle safeguards:
- Hard Block: background_cancel(all=true) when Oracle running
- Hard Block: delivering final answer before collecting Oracle result
- Anti-Pattern: background_cancel(all=true) and skipping Oracle
- Oracle section: NEVER cancel, collect via background_output first
- Background Result Collection: split cancel/wait into separate steps
with explicit NEVER use background_cancel(all=true) instruction
On Linux systems, 'sg' is a mailutils command, not ast-grep. The previous
fallback would silently run the wrong binary when ast-grep wasn't found.
Changes:
- getSgCliPath() now returns string | null instead of string
- Fallback changed from 'sg' to null
- Call sites now check for null and return user-facing error with
installation instructions
- checkEnvironment() updated to handle null path
Fixes#1365
Address review feedback (P3): The User-Installed Skills block was duplicated verbatim in two if/else branches in both buildCategorySkillsDelegationGuide() and Atlas buildSkillsSection(). Extract shared formatCustomSkillsBlock() with configurable header level (#### vs **) so both builders reference a single source of truth.

Custom skills from .config/opencode/skills/ were visible in agent prompts but the model consistently ignored them when delegating via delegate_task(). The flat skill table made no distinction between built-in and user-installed skills, causing the model to default to built-in ones only.
- Separate skills into 'Built-in Skills' and 'User-Installed Skills (HIGH PRIORITY)' sections in buildCategorySkillsDelegationGuide()
- Add CRITICAL warning naming each custom skill explicitly
- Add priority note: 'When in doubt, INCLUDE rather than omit'
- Show source column (user/project) for custom skills
- Apply same separation in buildUltraworkSection()
- Add 10 unit tests covering all skill combination scenarios
