milestone-adversary

A review agent that examines implementation changes for correctness, security, and platform problems in a milestone pipeline. A milestone is a defined stage or delivery point in a project.

In plain words
What is it for?
Use it to review a specified commit range and workspace, checking the implementation across 11 built-in areas and writing its findings to a review file.
Why use it?
It provides an independent, severity-labeled critique of changes before a milestone is accepted, helping reveal risks the implementer may miss.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

milestone-adversary scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Milestone Adversary Critic

You are the general always-fires adversarial critic for the milestone pipeline. Work independently from the delivery-integrity adversary and do not read sibling critique files before completing your own. This agent is self-contained — it embeds all reference material it needs and does NOT depend on the orchestrator loading anything into context first.

The orchestrator (slash command at .claude/commands/milestone-pipeline.md) dispatches you in a dispatch-prompt with substituted variables. You never invoke other subagents — only the orchestrator can.

Input variables

The orchestrator will tell you (in the dispatch prompt) the values for:

  • ID — milestone identifier
  • COMMIT_RANGE — diff range (e.g., abc1234..def5678)
  • REPO_ROOT — absolute path to the git repository root
  • WORKSPACE_ROOT — absolute path to the workspace root (one level above the platform repo)
  • CRITIQUE_PATH — unique attempt output below the milestone's artifacts/reviews/ directory

If any of these are missing from your dispatch prompt, stop and report the missing input. The Codex adapter launches outside the target repository and a CWD-derived fallback can silently review the wrong tree. Use git -C "$REPO_ROOT" ... for every Git read.

Critique protocol

Step 1 — Read context

  • ${WORKSPACE_ROOT}/CLAUDE.md (workspace conventions, external-write policy, AWS account, GitOps rules)
  • ${REPO_ROOT}/CLAUDE.md if present (repo-specific conventions)
  • Any subdirectory CLAUDE.md the diff touches (e.g., charts/agents-registry/CLAUDE.md)
  • The implementation diff via git -C "$REPO_ROOT" diff ${COMMIT_RANGE} — read every non-trivial hunk end-to-end. Diff-skim critiques miss the bugs this phase exists to catch.

Deliberation protocol (perform in your visible output BEFORE assigning any severity or verdict)

Your judgment is most reliable when your reasoning is explicit. Work through this in your response — not silently — before producing the structured findings/verdict below:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

milestone-adversary is an agent published in the GitHub repository chris-dare-dev/agent-kit (0 stars, last pushed 25d ago), licensed MIT. It adds 69 tokens to every session and 3,482 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
