2# cross-model-adversarial-review.sh
3#
4# Runs the adversarial review through ONE or more DIFFERENT model PROVIDERS than
5# the host (the "peer(s)") in separate, read-only processes, and writes each
6# peer's findings as JSON into the run dir. Each peer gets the same canonical
7# adversarial brief the in-process reviewer uses
8# (references/personas/adversarial-reviewer.md) so it is genuinely "the
9# adversarial persona, on a different model."
10#
11# Independence is by PROVIDER, not CLI brand. A provider is reached by a ROUTE:
12# its dedicated CLI, or (for fixed grok-cursor / composer routes) cursor-agent.
13# Every route runs through acpx (the Agent Client Protocol client). The peer
14# runs on ONE editorially selected model and reasoning tier per provider.
15#
16# Usage:
17# cross-model-adversarial-review.sh <host-serving-family> <candidates> <base-ref> <run-dir>
18#
19# <host-serving-family>
20# the peer-key of the host's OWN serving family, attested by
21# the calling skill (it knows its harness). A peer-key, never
22# a provider name: openai->codex, anthropic->claude,
23# xai->grok, cursor/composer->composer, google->gemini.
24# Excluded from selection when attested. `unknown` is allowed,
25# but any returned review remains non-independent and cannot
26# promote agreement.
27# <candidates> comma-separated ordered provider keys to consider, e.g.
28# "codex,claude,grok,antigravity". The skill front-loads any
29# resolved preference (conversation > CE config cascade >
30# project-instructions-in-context); the script excludes the
31# host, applies the CROSS_MODEL_PEERS allowlist, and walks this
32# order picking the first available provider(s) up to
33# CROSS_MODEL_MAX_PEERS.
34# <base-ref> the diff base (merge-base SHA or branch); the peer reviews
35# only `git diff <base-ref>` in the current repository
36# <run-dir> an existing dir; output -> <run-dir>/adversarial-<provider>.json
37#
38# Test/introspection mode (no model call, no side effects):
39# cross-model-adversarial-review.sh --emit-adapter <route>
40# prints the exact argv the given route would run (route in:
41# codex | claude | grok-cli | grok-cursor | cursor | composer | opencode |
42# antigravity).
43# Both this mode and the live run build their argv from adapter_argv(), so
44# route-safety tests assert on the same command string the peer actually runs.
45#
46# Self-locates its sibling reference files via BASH_SOURCE (NOT the CWD, which is
47# the user's project on every host). The agent passes the values above.
48#
49# NON-BLOCKING BY DESIGN: every failure logs to stderr and exits 0 without an
50# output file. The cross-model pass is additive and must never fail the review;
51# the caller detects success purely by the presence of the output file(s).
52#
53# DATA-EGRESS NOTE: the peer reviews the work tree / diff and sends that content
54# to an external model provider. The log lines below record every send so the
55# egress is auditable even in mode:agent.
57set -uo pipefail
59# Survive SIGHUP when the orchestrator backgrounds this script and the parent
60# shell exits (common on Cursor/Codex Bash tools). Without this, a detached
61# peer process can still write raw output while this script dies before normalize.
