feat: tool trace + platform instructions (review-passed) by HongmingWang-Rabbit · Pull Request #1686 · EnterOS-AI/enter-os-core

HongmingWang-Rabbit · 2026-04-22T23:18:45Z

Summary

Two platform-level observability + control features. Both passed comprehensive code review with all blockers + high-severity issues fixed.

1. Tool Trace

Every A2A response now includes a tool_trace list (tool name, input, output_preview) in Message.metadata, stored in new activity_logs.tool_trace JSONB column. Pairs start/end events via run_id so parallel tool calls work correctly. Capped at 200 entries to prevent runaway-loop bloat.

2. Platform Instructions

Configurable rules with global/workspace scope, fetched at workspace startup and prepended to system prompt. CRUD API + /workspaces/:id/instructions/resolve (gated by wsAuth — no cross-workspace enumeration). CHECK constraints enforce 8KB content cap to prevent token-budget DoS. Team scope reserved in schema for future migration.

Review fixes applied

✅ Removed team-scope queries (teams/team_members tables don't exist)
✅ Mounted Resolve under wsAuth (was open to network — IDOR fix)
✅ Added length validation (8KB content, 200 char title) in handler + DB CHECK
✅ Tool-trace pairs via run_id (was fragile to parallel calls)
✅ Capped tool_trace at 200 entries
✅ Python boot timeout 10s → 3s, added bearer auth header
✅ Replaced print with logger.warning, strings.Builder for merged prompt
✅ Removed dead code

…ability Every A2A response now includes a tool_trace — the list of tools/commands the agent actually invoked during execution. This enables verifying agent claims against what they actually did, catches hallucinated "I checked X" responses, and provides an audit trail for the CEO to control hundreds of agents by checking the top-level PM's trace. Changes: - Python runtime: collect tool name/input/output_preview on every on_tool_start/on_tool_end event, embed in Message.metadata.tool_trace - Go platform: extract tool_trace from A2A response metadata, store in new activity_logs.tool_trace JSONB column with GIN index - Activity API: expose tool_trace in List and broadcast endpoints - Migration 039: adds tool_trace column + GIN index Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Adds a configurable instruction injection system that prepends rules to every agent's system prompt. Instructions are stored in the DB and fetched at workspace startup, supporting three scopes: - Global: applies to all agents (e.g., "verify with tools before reporting") - Team: applies to agents in a specific team - Workspace: applies to a single agent (role-specific rules) Components: - Migration 040: platform_instructions table with scope hierarchy - Go API: CRUD endpoints + resolve endpoint that merges scopes - Python runtime: fetches instructions at startup via /instructions/resolve and prepends them to the system prompt as highest-priority context Initial global instructions seeded: 1. Verify Before Acting (check issues/PRs/docs first) 2. Verify Output Before Reporting (second signal before reporting done) 3. Tool Usage Requirements (claims must include tool output) 4. No Hallucinated Emergencies (CRITICAL needs proof) 5. Staging-First Workflow (never push to main directly) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

BLOCKERS fixed: - instructions.go: Drop team-scope queries (teams/team_members tables don't exist in any migration). Schema column kept for future. Restored Resolve to /workspaces/:id/instructions/resolve under wsAuth — closes auth gap that allowed cross-workspace enumeration of operator policy. - migration 040: Add CHECK constraints on title (<=200) and content (<=8192) to prevent token-budget DoS via oversized instructions. - a2a_executor.py: Pair on_tool_start/on_tool_end via run_id instead of list-position so parallel tool calls don't drop or clobber outputs. Cap tool_trace at 200 entries to prevent runaway loops bloating JSONB. HIGH fixes: - instructions.go: Add length validation in Create + Update handlers. Removed dead rows_ shadow variable. Replaced string concatenation in Resolve with strings.Builder. - prompt.py: Drop httpx timeout 10s -> 3s (boot hot path). Switch print to logger.warning. Add Authorization bearer header from MOLECULE_WORKSPACE_TOKEN env var. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

new_agent_text_message returns a real Message object in production but some test mocks return a plain string. Guard with hasattr + try/except so the tool_trace assignment doesn't crash test_non_stream_events_ignored.

…m 24h retro Created the missing SHARED_RULES.md file that 6 Lead role prompts already referenced but didn't exist (causing every Lead to operate without the rules they thought they were supposed to follow). Rules derived from real failure modes observed in the 2026-04-23 retro: 1. Verify before claiming — every factual claim needs tool output 2. CRITICAL/P0/URGENT requires raw evidence — file:line + repro command 3. Circuit breaker — stop the retry cascade after 3 same-error failures 4. Do not invent phases, deadlines, or features — verify in PLAN.md 5. Token expiry is a known issue, not a P0 — auto-refresh handles it 6. Slack noise discipline — dedupe within 4h windows 7. Identity tag every external comment — [<role>-agent] prefix 8. Staging-first workflow, no exceptions Updated 33 role system prompts to reference the new SHARED_RULES.md so the rules actually flow into context for every workspace. Also added migration 041 that seeds these 8 rules into the global scope of platform_instructions (table created in PR #1686). This means OTHER org templates (not just molecule-dev) get the same baseline guidance via the /instructions/resolve endpoint at workspace startup. 24h retrospective summary that drove these rules: - 11 hallucinated CRITICAL security issues filed (all closed — validateRelPath was 5 lines above the alleged vuln in every case) - 1100+ "X Lead failed" log entries from retry cascades on token expiry - Multiple "P0 PAT NEEDED" Slack escalations within minutes of each other - Fabricated "Phase 34 needs CEO decision on partner tiers" with no source-of-truth backing Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

PR #1686 introduced two platform-level features: - Tool Trace: tool_call list in A2A metadata, stored in activity_logs.tool_trace JSONB - Platform Instructions: admin-configurable instruction text (global/workspace scope), injected as first section of every agent's system prompt at startup Demo covers 5 scenarios: admin creates global instruction, workspace-scoped instruction, agent fetches resolved instructions at boot, admin lists instructions, and query activity logs with tool_trace.
