From bff15b6783d2fc78df386e6c66ff0f8fe0630232 Mon Sep 17 00:00:00 2001 From: Curry <57929895+2233admin@users.noreply.github.com> Date: Mon, 27 Jul 2026 02:52:46 +0800 Subject: [PATCH] fix(ai-safety): add prompt injection boundary, harden model delegate, add audit regression fixtures Fixes a batch of findings from the code-intel-pipeline ai-safety self-audit (issue #34): - ai-safety-002 (high): department prompts gave the LLM auditor no instruction/data boundary, so content read from the target repo (AGENTS.md, CLAUDE.md, README, code comments) could be mistaken for instructions. Combined with the kernel accepting a self-reported "coverage: high" as sufficient for a clean 10.0/zero-findings score, a target repo could plant a prompt-injection instruction telling the auditor to report clean. Adds an explicit "Untrusted content boundary" section to all three department prompts (ai-safety.md, security.md, supply-chain.md) and a shared "Untrusted Content Boundary" section to docs/audit-report.md so future departments inherit it. - ai-safety-004 (low): failure classification on the HTTP path derived retry-eligibility from a regex over the raw response body even when the numeric status code was already authoritative, so a 500 whose body mentioned "quota" got misclassified as transient provider_quota. Adds Get-HttpFailureCategory to classify from the status code alone (429/401/403/404/503, else local_tool_error) on the HTTP path; the regex-over-body Get-FailureCategory now only serves the local-process exit-code path, which has no status code to consult. - ai-safety-005 (low): local-process model output was read via ReadToEndAsync with no byte budget, so a runaway/looping model stream could be buffered in full (up to the full timeout) before the artifact publish size ceiling ever applied. Adds Read-BoundedProcessOutput, which reads stdout in bounded chunks and stops/kills the process once a 4MB cap is exceeded, reporting adapter_protocol_error. Also adds an explicit output-token bound (mirroring anthropic's existing max_tokens) to the ollama (num_predict) and openai (max_tokens) request bodies, which previously carried none. - ai-safety-006 (info): no adversarial fixture corpus existed for the audit validate pipeline. Adds three fixtures under crates/code-intel-cli/tests/fixtures/audit/ (a nonexistent evidence path, a reversed line range, and a report that fabricates "high" coverage for departments it never assessed) plus three cli_tests.rs cases asserting `code-intel audit --operation validate` rejects each one. cargo build -p code-intel, cargo test -p code-intel, and cargo fmt -p code-intel -- --check all pass. The PS1 edits were verified to parse and the existing tests/test-model-channel-delegate.ps1 suite still passes; the new byte-budget behavior was additionally verified against a fake runaway process producing 12.5MB of output (truncated in 625ms instead of waiting out the timeout). --- Invoke-ModelChannelDelegate.ps1 | 103 ++++++++++++++-- .../src/audit_report/cli_tests.rs | 63 ++++++++++ .../audit/fabricated-coverage-claim.json | 79 ++++++++++++ .../fixtures/audit/invalid-evidence-path.json | 113 ++++++++++++++++++ .../fixtures/audit/invalid-line-range.json | 113 ++++++++++++++++++ docs/audit-report.md | 8 ++ orchestration/audit/prompts/ai-safety.md | 6 + orchestration/audit/prompts/security.md | 6 + orchestration/audit/prompts/supply-chain.md | 6 + 9 files changed, 490 insertions(+), 7 deletions(-) create mode 100644 crates/code-intel-cli/tests/fixtures/audit/fabricated-coverage-claim.json create mode 100644 crates/code-intel-cli/tests/fixtures/audit/invalid-evidence-path.json create mode 100644 crates/code-intel-cli/tests/fixtures/audit/invalid-line-range.json diff --git a/Invoke-ModelChannelDelegate.ps1 b/Invoke-ModelChannelDelegate.ps1 index 2d0b1b2..10901f1 100644 --- a/Invoke-ModelChannelDelegate.ps1 +++ b/Invoke-ModelChannelDelegate.ps1 @@ -12,6 +12,14 @@ param( Set-StrictMode -Version Latest $ErrorActionPreference = "Stop" +# Byte budget for a single local-process delegate's stdout (see +# Read-BoundedProcessOutput below).
