SKILL: Resume Skill Listing Suppression
Domain: command-surfaces
Trigger: Apply when a resume flow already contains a previous skill_listing attachment and injecting another would waste ~600 tokens.
Source Pattern: Distilled from reviewed command-surface and listing-control patterns.
Core Method
Treat a resume run as continuing an existing transcript: before recomputing skill_listing, mark every command that already exists in the transcript as sent by setting suppressNext = true and filling sentSkillNames for that agentId. Return early without emitting any listing so the resume session does not repeat the large skill payload, even though the future process loses the ability to announce cross-process deltas until the next full session.
Key Rules
- Expose
suppressNextSkillListing() so external flows (conversation recovery) can set a flag that the next listing should be skipped.
- When building the attachment, check
suppressNext; if true, mark all current commands as sent, reset the flag, and return [].
- Accept the trade-off: cross-process delta coverage is deferred to the next non-resume session, but transcripts stay lean and avoid bursting the turn with redundant data.
- Keep the marking logic scoped to the process-local
sentSkillNames map keyed by agentId (main thread uses empty string) so per-agent delta tracking remains correct.
Example Application
When a session is resumed, call suppressNextSkillListing() right before getSkillListingAttachments so it returns [] and the transcript keeps the listing it already has instead of receiving another copy.
Anti-Patterns (What NOT to do)
- Do not clear
sentSkillNames or unset suppressNext during resume; you need to pretend the listing is still current.
- Do not let resume inject the full listing even once; the ~600-token delta is expensive for every restart.
