challenge

challenge is a skill for Claude Code from pablocaeg/claude-army. It costs 26 tokens per session (328 once invoked), scanned A, original, MIT.

A review simulation that checks current code changes against patterns from a lead reviewer's previous feedback. It requires a prepared forge analysis.

In plain words
What is it for?
Use it to inspect changed files, check factual claims and source links, and produce a prioritized list of possible review concerns and fixes.
Why use it?
It can reveal likely review questions or issues before you submit the changes for review.

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

challenge 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 7d 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.

What it actually says

Simulate the lead reviewer's feedback on the current changes. Uses reviewer patterns from the forge analysis.

Before Starting

  1. Read .context/forge-analysis.md for reviewer patterns
  2. If it doesn't exist, tell the user to run /claude-army:analyze first

Process

  1. Run git status and git diff --name-only to find all changes
  2. Read every changed/new file
  3. Apply reviewer checks in tier order (Tier 1 first, most likely to be raised)
  4. For factual claims (thresholds, tax classification, etc.): WebSearch to verify
  5. For source URLs: WebFetch to confirm accessibility

Output

Present findings as the lead reviewer would — questions, not demands:

## Review Simulation: [Reviewer Name]

### Questions (likely to ask)
**file:line** — [question in their voice]
Fix with: [which agent or direct edit]

### Issues (would flag)
**file:line** — [what's wrong]
Fix with: [which agent]

### What Looks Good
[acknowledge well-done parts]

### Fix Plan
| # | Issue | Fix Agent | Instruction |
|---|-------|-----------|-------------|
| 1 | ... | ... | ... |

Execution order: [dependencies]
Changes

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.
