feat: enable 15 additional feature flags in open build (#667)
* feat: enable 16 additional feature flags in open build
Activate features whose source is fully available in the mirror and
that have no Anthropic-internal infrastructure dependencies:
UI/UX: MESSAGE_ACTIONS, HISTORY_PICKER, QUICK_SEARCH, HOOK_PROMPTS
Reasoning: ULTRATHINK, TOKEN_BUDGET, SHOT_STATS
Agents: FORK_SUBAGENT, VERIFICATION_AGENT, MCP_SKILLS
Memory: EXTRACT_MEMORIES, AWAY_SUMMARY
Optimization: CACHED_MICROCOMPACT, PROMPT_CACHE_BREAK_DETECTION
Safety: TRANSCRIPT_CLASSIFIER
Debug: DUMP_SYSTEM_PROMPT
Also reorganize featureFlags into documented sections (disabled/upstream/new)
with inline comments explaining each flag's purpose.
* feat: add centralized GrowthBook defaults map for open build
Add _openBuildDefaults in the GrowthBook stub (no-telemetry-plugin.ts)
with all 66 runtime feature keys, organized by category with inline
comments describing each flag's purpose.
Override tengu_sedge_lantern (AWAY_SUMMARY) and tengu_hive_evidence
(VERIFICATION_AGENT) to true so these features work out of the box
without requiring manual ~/.claude/feature-flags.json setup.
Priority: feature-flags.json > _openBuildDefaults > upstream default
* feat: replace refusal language with positive security guidance
Remove refusal instructions from CYBER_RISK_INSTRUCTION since they are
redundant for Anthropic models (applied server-side) and useless for
uncensored models in multi-provider setups. Keep positive guidance for
security testing contexts and add red teaming support.
* Revert "feat: replace refusal language with positive security guidance"
This reverts commit 0463676a8f.
* fix: add EXTRACT_MEMORIES runtime gate overrides to open-build defaults
EXTRACT_MEMORIES was enabled at build-time but its runtime GrowthBook
gates (tengu_passport_quail, tengu_coral_fern) still defaulted to false,
preventing the feature from activating. Add both keys to
_openBuildDefaults so memory extraction works out of the box.
Also adds test coverage for _openBuildDefaults precedence behavior.
* docs: update GrowthBook runtime keys catalog to 88 keys
Expand the reference catalog in no-telemetry-plugin.ts from ~62 to 88
unique keys, covering all tengu_* call sites found in src/. Adds 27
previously undocumented keys including VSCode gates, dynamic configs
(auto-mode, cron, bridge), security gates, and KAIROS cron keys.
Adds "not exhaustive" disclaimer as suggested by Copilot reviewer.
Reorganizes categories with section dividers for readability.
