Cover two untested boundaries from #3412:
- _truncate_to_token_budget with positive budget exercises tiktoken
- _MAX_HISTORY_CHARS caps Recent History section in system prompt
Made-with: Cursor
Move all behavioral instructions out of identity.md into SOUL.md so that
each file has a single clear purpose:
- identity.md: capability facts only (runtime, workspace, format hints,
tool guidance, untrusted content warning)
- SOUL.md: behavioral rules (name, personality, execution rules)
The "Act, don't narrate" rule is refined into layered behavior: act
immediately on single-step tasks, plan first for multi-step tasks. This
eliminates the contradiction where identity said "never end with a plan"
but user SOUL.md said "always plan first".
- Convert skills summary from verbose XML (4-5 lines/skill) to compact
markdown list (1 line/skill) with inline path for read_file lookup
- Exclude always-loaded skills (e.g. memory) from the skills index to
avoid duplicating content already in the Active Skills section
- Skip injecting the Memory section when MEMORY.md still matches the
bundled template (i.e. Dream hasn't populated it yet)
