Session 21 — Phase 2 Prep: Tool Reference, Error Nudge, Auto-Reflection, Defence Suite

Date: May 11, 2026 Pushed to main: 7 files (2 modified, 5 new/updated)

What Changed

1. System Prompt — Full Tool Reference (prompts/J-system.txt)

Replaced the bare tool name list with a full reference showing exact arg formats for every tool. Critical addition:

run_str_replace — Surgical edit. Args is ONE JSON string:
  ACTION:{"tool": "run_str_replace", "args": ["{\"path\": \"app/chat.py\", \"old\": \"x = 1\", \"new\": \"x = 2\"}"]}

J failed the Option C test (Turn 4) because it didn't know run_str_replace takes a single JSON payload — it passed wrong arg formats 3x in a row. Now the exact format with an example is in the system prompt.

Prompt: ~260 → ~680 tokens. Leaves ~1370 for conversation at 2048 context.

Security tools also added to the reference:

run_shield <sub> [path]  — Shard defence: verify, baseline, autorun, wipe <path>.
run_scan <sub> [target]  — Host audit: ports, creds, security, network, services, permissions, full.
run_bridge <sub>         — Remediation: report, script, rescan.

2. Error-Aware Retry Nudge (app/chat.py)

When a tool returns an error and J has remaining budget, the continuation nudge now says:

"Your last tool call FAILED: [actual error message]. Fix the arguments and try again."

Previously the nudge was a generic "Continue." which let J repeat the same broken call 3x without knowing what went wrong. The error is truncated to 200 chars to stay within context budget.

3. Auto-Reflection (app/chat.py)

Added _maybe_auto_reflect() helper function. Fires after every memory append at all 3 sites:

  • Line 518: after _run_turn() completes (LLM-handled turns)
  • Line 811: after each plan/execute step completes
  • Line 1240: after router-handled turns

When working memory exceeds 32KB, automatically builds the reflection prompt, streams LLM output, parses, and compresses. This was the auto-reflection bug that J was supposed to fix in Option C — we fixed it ourselves after J failed the task.

/reflect stays as manual override.

4. Defence Suite — Three-Layer Security Toolkit (NEW)

Three new tool scripts registered in tools/run/:

Layer 1 — SHIELD (tools/run/shield.py, 194 lines) Shard self-defence when plugged into untrusted machines.

  • verify — SHA-256 integrity check against baseline, flags CRITICAL changes to core dirs (app/, prompts/, tools/)
  • baseline — Generate/update integrity hashes
  • autorun — Detect and kill autorun.inf at USB root (classic malware vector)
  • wipe <path> — 3-pass random overwrite + delete (FAT32 doesn't zero on delete)

Layer 2 — SCAN (tools/run/scan.py, 475 lines) Host security auditor. All pure Python stdlib (socket, subprocess, os).

  • ports [target] — TCP scan of 20 common ports with risk levels
  • creds [path] — Regex sweep for API keys, passwords, tokens (AWS, GitHub, Slack, OpenAI, generic patterns)
  • security — Windows-specific: firewall, UAC, Defender, RDP, password policy, auto-updates
  • network — Interfaces, listening ports, open shares, ARP table (spoofing detection via duplicate MACs)
  • services — Running service enumeration, flags known risky services (telnet, FTP, SNMP, etc.)
  • permissions [path] — Sensitive file permission audit (.env, .ssh, id_rsa, credentials, etc.)
  • full [path] — All audits combined, saves structured findings to logs/last_audit.json

Layer 3 — BRIDGE (tools/run/bridge.py, 252 lines) Remediation generator. Reads audit findings and produces actionable output.

  • report — Markdown remediation report: risk-grouped findings with exact fix commands
  • script — Auto-generates .bat (Windows) or .sh (Linux) fix script from findings
  • rescan — Re-runs full audit and compares against previous: shows fixed, new, remaining

All three layers registered in tools/run/registry.json with appropriate timeout settings (30s for shield, 120s for scan and bridge).

Design philosophy: Same as the router — deterministic tools do the work, the LLM focuses on judgment. The defence suite runs outside the LLM loop at zero inference cost.

What it won't be:

  • Not a replacement for Nessus/Metasploit/Burp — no exploit DB, no fuzzing
  • No CVE lookups — no network means no NVD
  • Windows-first — Linux audit commands would need a second set
  • No encryption library — vault feature deferred (would need cryptography as 3rd dep)

5. Registry Updated (tools/run/registry.json)

Three new entries: run_shield, run_scan, run_bridge with proper arg schemas and side effects.

6. README Updated (README.md)

  • Added Defence Suite badge
  • Added Defence Suite feature row (21+ tools)
  • Added full Defence Suite section with tool table and workflow example
  • Updated architecture tree (21+ tools)
  • Updated project stats (94 files, 66 modules, 3-layer defence suite)
  • Added security commands to commands table
