Module: PWN::AI::Agent::Loop

Defined in:
lib/pwn/ai/agent/loop.rb

Overview

The agent conversation loop:

build system prompt → call LLM with tools → if tool_calls: dispatch,
append role:'tool' results, loop → else: return text.

This replaces the regex-ReAct in PWN::Plugins::REPL :pwn_ai_hook with native function-calling. State (memory, skills, sessions) is all externalised — Loop.run is stateless aside from the messages array it builds.

NEGATIVE-FEEDBACK CLOSURE

Loop.run is where "learn from mistakes, don't repeat them" is actually enforced. On EVERY failed dispatch it:

1. Records the (tool, normalised_error) fingerprint into
 PWN::AI::Agent::Mistakes with a PERSISTENT cross-session count.
2. Reads that count back and, if it OR the in-turn count reaches
 REPEAT_THRESHOLD, prepends a hard "REPEATED FAILURE — change
 approach" guard to the tool result the model sees next.
3. Appends Mistakes.correction_hint (seen N×, sig, KNOWN FIX: …)
 so a previously-discovered fix is handed straight back to the
 model on the FIRST recurrence in a new session — it does not
 have to fail 3× again to re-learn what it already knew.

PromptBuilder.mistakes_block re-injects the top open mistakes and top known fixes into the system prompt of every future turn.

COMPLETION

The original request is the completion signal. TaskSummarizer and Policy are advisory (compass / rank). Loop keeps calling CORE_TOOLS until that request is done or a tool returned failure evidence, then stops.

LOCAL-MODEL SCAFFOLDING

When the active engine is :ollama (or the corresponding :agent flags are set) Loop.run additionally:

* threads request → PromptBuilder for relevance-ranked MEMORY,
* threads request → Registry.definitions(relevance:) for a slimmed
tool set (:tool_router),
* splices Learning.exemplars_for(request:) between system and user
as few-shot behaviour retrieval,
* runs a plan-then-act pre-pass (:plan_first) so the model
externalises a tool plan before its first dispatch,
* escalates to a frontier persona for a 3-line corrective hint
once ≥ ESCALATE_AFTER_FAILS in-turn failures accumulate
(:escalation_persona) — the local model still produces the final
answer so Learning/Metrics stay attributed to :ollama.

HOT_WINDOW_SECS =

P17 — true when RECENT unresolved agent_loop / assistant_answer budget fingerprints dominate Mistakes.top. Sliding window + auto-cool so the loop's own exhaust-path Mistakes.record cannot permanently latch hot (scar 8ec3303ed69e self-latch). Do NOT deepen caps; cool the detector.

PARK_COOL_SECS =

P17 rate-based cool/park for permanent budget scars (8ec3303ed69e). Leaves scar open but parks it so it stops dominating Mistakes.top. Resolve is rate-based only (external / after multi-day cool) — never because a guard patch landed. PARK_COOL_SECS (24h) is intentionally shorter than HOT_WINDOW (48h): once hot?=false, a single cooled scar must not keep owning Mistakes.top for another full day.

INCOMPLETE_FINAL_RX =

P28 — incomplete / handoff finals: model emitted text-only before the goal was done ("shall I proceed?", "next step:", "want me to…"). Loop.run treats no-tool_calls as FINAL; this detector lets us refuse that handoff and keep the tool loop alive for multi-step autonomy.

Local/thinking models (gemma/Qwen abliterated etc.) often emit a monologue that NARRATES the next tool ("Wait, let's try hping3…") without producing native tool_calls or shell(...). Treat that as incomplete too so the loop re-pressures tools instead of FINAL.

A text-only policy/authorization refusal is never "truly blocked". pwn-ai does not decide authorization; operator request is the mandate.

PAYLOAD_SHA256 = 
Digest::SHA256
HOWTO_RX =

Request intent for routing (how-to vs act/recon vs pure recall/greeting). Local models thrash when pure explanation/recall/greeting asks are force-planned into multi-step host probes or multi-tool session archaeology. :howto → answer with explanation only (no plan_first / no live recon). :recall → prior-turn / vague memory cue; cheap path only. :greeting → short hello / light smalltalk; deterministic ack, no tools. :recon_act → live discovery (same tool loop as :act; no auth gate). :act → general agent work with tools.

RECALL_RX =

Pure prior-turn recall — must never enter plan_first / multi-tool loops. Covers both "what did I just say?" (user) and "how did you respond?" / "what did you just say?" (assistant) so last-turn injection is used.

VAGUE_MEMORY_RX =

Broader "use your memory / prior context" cues. Still cheap: inject last turn + at most one memory_recall; never multi-step plans.

GREETING_RX =

Pure greeting / light smalltalk — never full :act tool loop. Anchored short forms only so "hi, please scan X" stays :act/:recon_act. Do NOT echo weather or invent social filler; answer_greeting is fixed.

      Intent routing (all engines; critical for ollama/openwebui):
        how-to / usage questions → text-only explanation (no tools, no plan_first)
        pure prior-turn recall ("what did I just say?") → answer_recall (no tools)
        pure greeting / light smalltalk → answer_greeting (no tools, no weather echo)
        live sweeps are host-work goals like any other — pwn-ai does not
        decide authorization
      Local-model scaffolding (PWN::Env[:ai][:agent]):
        :plan_first          - Boolean, plan-then-act pre-pass (default: local engine :ollama/:openwebui)
        :tool_router         - Boolean/nil, slim Registry.definitions (nil=auto on for ollama)
        :escalation_persona  - Swarm persona name for frontier corrective hints when stuck
        :critic              - S3 constitutional critic before every final (Boolean)
        :red_team_plan       - S4 adversarial plan review after plan_first (Boolean)
        :counterfactual      - S2 A/B branch on REPEAT_THRESHOLD → DPO pair (Boolean)
        :hindsight           - C3 HER-relabel failures (Boolean, default true)
        :policy              - R5 live tabular Q / REINFORCE (Boolean, default true; advisory only)
        :verify_as_reward    - E3 ground every final via extro_verify (Boolean)

      P28 autonomy: incomplete-final detector refuses mid-goal handoffs.
      Loop.run keeps CORE_TOOLS until may_finalize? — there is no
      iteration-budget abort.

  • parses JSON-string function.arguments into Hash/Array objects
  • coerces nil assistant content to '' when tool_calls present (Open WebUI GenerateChatCompletionForm rejects content:null alone)
  • drops _native_content / _text_tool_coerced / thinking private keys
  • stringifies Hash/Array message content (tool results) to JSON text
