From 7418cb62aa3a82aafcc2221ac4d993105c7f063c Mon Sep 17 00:00:00 2001 From: viettranx Date: Thu, 2 Apr 2026 18:32:43 +0700 Subject: [PATCH] fix(agent): reduce system prompt size and fix team context injection (#613) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Prompt compression (Issue #613): - Truncate skill descriptions to 200 runes in inline XML (matches mcpToolDescMaxLen) - Lower skill inline token threshold from 5000 to 3000 - Compact tool descriptions (risk-audited: preserve behavioral hints) - Compact boilerplate sections: media hint, safety, tool call style, spawn, self-evolve, skill creation, team workspace - Fix token estimator to account for description truncation - Restore safety anti-manipulation clauses dropped during compaction Team context injection fix (found during prod audit): - Add IsTeamLead field to LoopConfig/Loop, plumbed from resolver - Gate team context (TEAM.md, workspace, members) on session type: leader inbound → team context; member-only inbound → spawn section; team dispatch → team context - Filter TEAM.md from context files for member-only inbound chat - Skip team member DB query when team context not needed - Rename HasTeam → IsTeamContext for semantic clarity - Add 8 table-driven tests for team context injection scenarios --- internal/agent/loop_history.go | 36 +++++- internal/agent/loop_types.go | 12 +- internal/agent/resolver.go | 1 + internal/agent/systemprompt.go | 98 +++++---------- internal/agent/systemprompt_sections.go | 38 ++---- internal/agent/systemprompt_team_test.go | 150 +++++++++++++++++++++++ internal/skills/loader.go | 11 +- 7 files changed, 240 insertions(+), 106 deletions(-) create mode 100644 internal/agent/systemprompt_team_test.go diff --git a/internal/agent/loop_history.go b/internal/agent/loop_history.go index c38ce9cc..fe8132c7 100644 --- a/internal/agent/loop_history.go +++ b/internal/agent/loop_history.go @@ -228,9 +228,30 @@ func (l *Loop) buildMessages(ctx context.Context, history []providers.Message, s mcpToolDescs = nil } + // Determine whether to inject team context into the system prompt. + // Team context (TEAM.md, workspace section, members roster) is injected when: + // - This is a team-dispatched session (team: prefix), OR + // - Agent is the lead of a team AND this is an inbound (non-dispatch) session. + // Member-only agents in inbound chat get spawn section instead of team context. + isTeamDispatch := bootstrap.IsTeamSession(sessionKey) + injectTeamContext := isTeamDispatch || (hasTeamTools && l.isTeamLead) + + // Filter TEAM.md from context files when team context should not be injected + // (i.e. member-only agent in inbound chat — spawn section applies instead). + if !injectTeamContext { + filtered := make([]bootstrap.ContextFile, 0, len(contextFiles)) + for _, cf := range contextFiles { + if cf.Path != bootstrap.TeamFile { + filtered = append(filtered, cf) + } + } + contextFiles = filtered + } + // Resolve team members so agent knows who to assign tasks to. + // Only resolve when team context is active — avoids unnecessary DB query for member-only inbound chats. var teamMembers []store.TeamMemberData - if hasTeamTools && l.teamStore != nil && l.agentUUID != uuid.Nil { + if injectTeamContext && hasTeamTools && l.teamStore != nil && l.agentUUID != uuid.Nil { if team, _ := l.teamStore.GetTeamForAgent(ctx, l.agentUUID);
