Sisyphus can now fall back through Kimi and OpenAI models when Claude
is unavailable, enabling OpenAI-only users to use Sisyphus directly
instead of being redirected to Hephaestus.
Runtime chain: claude-opus-4-6 max → k2p5 → kimi-k2.5 → gpt-5.4 medium → glm-5 → big-pickle
CLI chain: claude-opus-4-6 max → k2p5 → gpt-5.4 medium → glm-5
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.
Restructure from 13 scattered XML blocks to 8 dense blocks with 9
named sub-anchors, following OpenAI GPT-5.4 prompting guidance and
Oracle-reviewed context preservation strategy.
Key changes:
- Merge think_first + intent_gate + autonomy into unified <intent>
with domain_guess classification and <ask_gate> sub-anchor
- Add <execution_loop> as central workflow: EXPLORE -> PLAN -> ROUTE ->
EXECUTE_OR_SUPERVISE -> VERIFY -> RETRY -> DONE
- Add mandatory manual QA in <verification_loop> (conditional on
runnable behavior)
- Move <constraints> to position #2 for GPT-5.4 attention pattern
- Add <completeness_contract> as explicit loop exit gate
- Add <output_contract> and <verbosity_controls> per GPT-5.4 guidance
- Add domain_guess (provisional) in intent, finalized in ROUTE after
exploration -- visual domain always routes to visual-engineering
- Preserve all named sub-anchors: ask_gate, tool_persistence,
parallel_tools, tool_method, dependency_checks, verification_loop,
failure_recovery, completeness_contract
- Add skill loading emphasis at intent/route/delegation layers
- Rename EXECUTE to EXECUTE_OR_SUPERVISE to preserve orchestrator
identity with non-execution exits (answer/ask/challenge)
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.
Add <parallel_tool_calling> and <tool_usage_rules> blocks that GPT-5.4
treats as first-class behavioral contracts. Add parallel-planning question
to <think_first>, strengthen Exploratory route in intent gate, and add
IN PARALLEL annotations to verification loop.
Split monolithic hephaestus.ts into directory with model-specific prompt
variants (gpt-5-4.ts, gpt-5-3-codex.ts, gpt.ts) mirroring the
sisyphus-junior pattern. Generic gpt.ts uses pre-codex-tuning prompt as
fallback for non-specific GPT models.
Also adds isGpt5_4Model and isGpt5_3CodexModel helpers to types.ts.
The librarian agent's system prompt contained incorrect example function
names for the Exa web search tool, causing the agent to call a non-existent
tool 'websearch_exa_web_search_exa' instead of the correct
'websearch_web_search_exa'.
Fixes#2242
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.
The auto-commit section instructed Hephaestus to automatically commit after
implementation work. Users who didn't know about this behavior would get
surprise commits — a trust-breaking behavioral change flagged by 5 Oracle
reviews as the sole publish blocker for 3.9.0.
date is already injected by OpenCode's system.ts. omo-env now contains only
Timezone and Locale, which are stable across requests and never break cache.
Current time with HH:MM:SS changed every second, invalidating the prompt cache
on every request. Date-level precision is sufficient; timezone and locale are
stable. Removes Current time field entirely from createEnvContext output.
The test 'hephaestus is created when github-copilot provider is connected'
had incorrect expectation. github-copilot does not provide gpt-5.3-codex,
so hephaestus should NOT be created when only github-copilot is connected.
This test was causing CI flakiness due to incorrect assertion and
missing readConnectedProvidersCache mock (state pollution between tests).
Also adds cacheSpy mock for proper isolation.
- fix(hooks): skip todo continuation when agent has pending question (#1888)
Add pending-question-detection module that walks messages backwards
to detect unanswered question tool_use, preventing CONTINUATION_PROMPT
injection while awaiting user response.
- fix(config): allow custom agent names in disabled_agents (#1693)
Change disabled_agents schema from BuiltinAgentNameSchema to z.string()
and add filterDisabledAgents helper in agent-config-handler to filter
user, project, and plugin agents with case-insensitive matching.
- fix(agents): change primary agents mode to 'all' (#1891)
Update Sisyphus, Hephaestus, and Atlas agent modes from 'primary'
to 'all' so they are available for @mention routing and task()
delegation in addition to direct chat.
Counter Gemini's tendency to skip Phase 0 intent classification by
injecting a mandatory self-check gate before tool calls. Includes
intent type classification, anti-skip mechanism, and common mistake
table showing wrong vs correct behavior per intent type.

Add 'gemini' to prompt source types and route Gemini models to new
Gemini-optimized prompts via isGeminiModel detection. Update barrel
exports for all 3 agent modules. All existing tests pass.
