T6 of TASK-rectification-grounding-20260927.
- skill-slice.ts: per-action slice rule as a code constant, keyed on heading
titles (evidence: 「ConversationFocus 与意图承接」「批量证据与日期真实性」, i.e.
§5/§7 of the 10.0.x layout); other actions and any bound Skill without those
headings (9.0.0) get the whole body, so historical Cases still run with their
exact bound Skill (BUG-621).
- The rectification Agent declares providesSkillDiscovery "on-demand"
(rectificationSkillBoundProcessor): no <available_skills> block with a temp
path and no "call the skill tool" system message; getSkill still loads the
bound package.
- Measured on a real Agent + recording model (public AA case, estimate = CJK
chars + other chars / 4): fixed overhead per call 12,002 → 6,471 tokens
(step 0: 8,440 → 2,909). Skill text unchanged; no version bump.
