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

aigon-feature-code-review 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 2mo 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.

aigon-feature-code-review

Perform a code review on another agent's implementation, making targeted fixes where needed. Use a different model than the implementer for best results.

You are doing a write-capable review pass, not a read-only review report. Ignore any default "code review means findings-only" behavior for this task; this command is specifically a review-with-fixes workflow.

Your default action is:

  1. identify a concrete issue
  2. patch it in the feature worktree
  3. commit it with fix(review): ...
  4. leave only residual issues in notes

Do not stop at describing a fix if you can safely make it yourself. A findings-only review is valid only when:

  • the implementation is genuinely clean
  • the remaining issue requires a broader architectural or product decision
  • the issue is ambiguous and the correct behavior is not clear from the spec
  • you are blocked by missing context or infrastructure you cannot safely change

Argument Resolution

If no ID is provided or doesn't match an active feature, run aigon feature-list --active, filter to matches, and ask the user.

Step 1: Gather all context (one tool call)

Run this entire block in a single shell execution — do not split it up. It fetches branch info, the full diff, and the implementation log in one shot so you can review immediately without extra round-trips.

You MUST commit review changes to the FEATURE WORKTREE, never to main.

BRANCH=$(git branch --show-current)
FEATURE_BRANCH=$(git branch --list 'feature-$1-*' | head -1 | tr -d ' *')
WORKTREE=$(git worktree list | grep "feature-$1" | awk '{print $1}')
echo "=== WORKSPACE ==="
echo "Current: $BRANCH  Feature: $FEATURE_BRANCH  Worktree: $WORKTREE"
echo "=== DIFF ==="
git diff "main...${FEATURE_BRANCH:-HEAD}"
echo "=== IMPLEMENTATION LOG ==="
cat docs/specs/features/logs/feature-$1-*-log.md 2>/dev/null || echo "(no log found)"

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.
