os-context

Prompt-composer SessionStart plugin (renamed 2026-07-13 from os-orchestration): concatenates prompts/session-start/*.md into one additionalContext block, injected at session start and after compaction/resume.

Component map

• prompts/session-start/ — 4 files, concatenated in filename order: 10-orchestration.md (session-orchestration + delegation-economics rules — do not edit without explicit approval, per eval-wording sensitivity), 20-kickoff-conventions.md, 30-standing-safety.md, 40-decision-memos.md.
• hooks/inject.py — the composer; enforces the line-budget guard (120/240).
• hooks/hooks.json — SessionStart wiring, matcher startup|resume|clear|compact.
• skills/audit-sessions/SKILL.md — /os-context:audit-sessions, the biweekly orchestration IRL audit against 10-orchestration.md's shipped rules; see skills/audit-sessions/references/rubric.md.
• audit/bin/{audit-stats,extract} — deterministic driver scripts the audit skill calls; skill-local, not a plugin-root bin/.
• tests/hook_test.py — unittest, covers compose order + budget logic.
• eval/ — Eval harness (prompted grid, scenarios + scenarios-reserve/); eval discipline (reserves never read informally) per root CLAUDE.md.
