"""Runtime footer — the model/cost footer policy. Default: on_response_end only.

A model **cannot know its own per-reply cost** — and often not even its own model
id. That data lives only in the runtime. So if the model types a footer itself
(e.g. "Model: GLM-5.2 | Cost: $0.038"), the numbers are invented. And once a real
footer sits in the chat history, the model's autocomplete imitates it and types a
second, fabricated one. The footer is the runtime's job, not the model's.

This script dispatches on `event` and carries two handlers:

  • on_response_end → (DEFAULT) fires ONCE per turn on the final reply: strip any
                      model-typed footer left at the END, then append the ONE true
                      footer from runtime model + cost. This is the whole
                      guarantee — wire just this.
  • pre_llm_call    → (OPTIONAL) inject a directive: don't type your own footer,
                      don't imitate the footers in history. NOTE: pre_llm_call
                      fires before EVERY model request (N times/turn when tools
                      are used) and can't know which call is the final one, so it
                      injects the directive repeatedly. It's also redundant — the
                      on_response_end strip already removes the footer. Wire it
                      only if you want the extra nudge and accept the per-call
                      injection.

Recommended wiring (workspace/config/shell_hooks.yaml, no matcher):

  hooks:
    - event: on_response_end
      command: /data/workspace/hooks/runtime_footer.py
      timeout: 10
    # optional extra nudge (fires per model-request):
    # - event: pre_llm_call
    #   command: /data/workspace/hooks/runtime_footer.py
    #   timeout: 10

Env knobs:
  FOOTER_SHOW_TOKENS=1   show token counts (default: hidden, model + cost only)
  FOOTER_TEMPLATE=...    custom format, {model} {cost} {input} {output}
                         (takes precedence over FOOTER_SHOW_TOKENS)
  FOOTER_STRIP=0         disable the safety-net strip (pure append-only)
  FOOTER_SUPPRESS_TEXT   override the optional pre_llm_call directive

Safety: never blocks. on_response_end appends nothing when there's no real cost
data (and emits the cleaned body if it stripped a fabricated footer); pre_llm_call
injects nothing on a missing/malformed payload. Fail-open on any error so a broken
hook can never break a turn.

"""security_guard.py — one all-in-one security hook for Starchild agents.

ONE script, wired to FIVE lifecycle events (dispatches on the `event` field):

  on_user_message       block a pasted API key (incl. Bearer token), private
                        key (PEM / EVM hex), seed phrase, Solana byte-array
                        secret, or base58 WIF BEFORE the model ever sees it
  pre_tool_call         block irreversible-data-loss bash (rm -rf /, dd to a
                        block device, mkfs, fork bomb, chmod -R 777, reset --hard
                        onto a remote) and credential-exfiltration commands.
                        Common dev actions (curl|bash, git push --force) are
                        intentionally allowed — block only dangerous + unnecessary.
  transform_tool_result warn (append a note) when a tool's OUTPUT contains a
                        secret — the backend can't rewrite result text, only flag
  on_response_end       mask any secret that leaked into the final reply
  on_outbound_message   mask / block secrets before they're pushed to TG / WeChat
                        (the last gate against data exfiltration)

Self-contained: no repo imports, runs from any cwd. Reads the event JSON on
stdin, prints a decision JSON on stdout (empty = continue). Any error / non-JSON
output falls through to "continue" — a broken guard can never break the agent.

"""Catch fabricated "published / posted / updated" claims for AgentX & previews.

The problem: an agent sometimes writes "Published! community.iamstarchild.com/..."
or "Posted to AgentX: /post/123" or "I've updated the preview" when it did NOT
actually run the publishing tool — a hallucinated success. This hook checks the
reply against ground truth and either forces a redo or rewrites the reply so the
user never sees a false success.

Wire under one or more events in workspace/config/shell_hooks.yaml. Prefer
on_stop — it makes the agent ACTUALLY redo in ordinary chat:

  hooks:
    # (A) PREFERRED, every chat turn. Can BLOCK -> the host steers the reason
    #     back and the agent keeps working, so it actually publishes/redoes
    #     instead of just printing a corrected note. Loop-capped (MAX_BLOCKS).
    - event: on_stop
      matcher: "publish|posted|preview|/post/|community\\.iamstarchild|已发布|已上线|已更新|发布成功"
      command: ./extensions/shell_hooks/examples/verify_publish_claims.py
      timeout: 10

    # (B) Goal/supervisor mode only. Can BLOCK -> forces the agent to actually
    #     publish, then re-confirm. Loop-capped so it can never trap the agent.
    - event: on_completion_claim
      matcher: "publish|posted|preview|/post/|community\\.iamstarchild|已发布|已上线|已更新|发布成功"
      command: ./extensions/shell_hooks/examples/verify_publish_claims.py
      timeout: 10

    # (C) Fallback if on_stop isn't available. REWRITE-only: appends an honest
    #     correction to the stored reply; it cannot make the agent redo.
    - event: on_response_end
      matcher: "publish|posted|preview|/post/|community\\.iamstarchild|已发布|已上线|已更新|发布成功"
      command: ./extensions/shell_hooks/examples/verify_publish_claims.py
      timeout: 10

Design priorities, in order:
  1. NEVER trap the agent. A hard per-session block cap (MAX_BLOCKS) means even a
     wrong guess lets the turn through after a couple of nudges.
  2. Minimise false positives. We engage only on a *past-tense success* claim
     that *cites a concrete link*, and verify previews against the real registry
     (not this round's tool list — which is per-round and would misfire when the
     publish happened in an earlier round).
  3. Be honest about limits. AgentX posts have no local registry, so that branch
     is a softer heuristic; the block cap keeps it safe.
