Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.02743 |
| Opus 5.5 | $0.00021 | $0.01097 |
| Sonnet 5.5 | $0.00010 | $0.00549 |
| Haiku 4.5 | $0.00005 | $0.00274 |
Grade A, and why
adversarial-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.
How it starts
The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adversarial Documentation Review
Catch what manual review misses: undocumented features, unverified claims, misleading examples.
When to Use This Skill
- README/docs review: "Is this README accurate and complete?"
- API documentation audit: "Are all methods documented?"
- Performance claims: "Are these benchmarks real?"
- Migration guides: "Does this show all breaking changes?"
Red flags that trigger adversarial review:
- Quantitative claims without evidence ("5x faster")
- Selective examples (shows 1 of 8 subcommands)
- Version-dependent claims (could be outdated)
The Adversarial Difference
| Manual Review | Adversarial Review |
|---|---|
| "Looks comprehensive" | 82.5% coverage (33/40 methods) |
| "Examples seem right" | 7 methods undocumented (proven via derivation) |
| "5x claim noted" | Unverified (no benchmark files found) |
| Miss check method gap | Formal proof 4 variants missing |
Instructions
Phase 1: Exhaustive Enumeration (Ground Truth)
Build complete inventories from source code, not docs.
For CLI Tools:
# Extract ALL commands and subcommands
uv run tool --help | grep "Commands:" -A 100
uv run tool add --help | awk '/Commands:/,/^$/'
uv run tool check --help | awk '/Commands:/,/^$/'
# Count total
echo "add subcommands: 8 total"
echo "check subcommands: 7 total"
For Python APIs:
# Extract all public methods from source
import ast
with open('api/table.py') as f:
tree = ast.parse(f.read())
for node in ast.walk(tree):
if isinstance(node, ast.ClassDef) and node.name == 'Table':
methods = [m.name for m in node.body
if isinstance(m, ast.FunctionDef)
and not m.name.startswith('_')]
print(f"Total public methods: {len(methods)}")
for m in sorted(methods):
print(f" {m}")
Critical: This is your ground truth. Docs must be measured against THIS, not assumed complete.
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.

adversarial-review is a skill published in the GitHub repository nlebovits/parseltongue-claude (0 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 52 tokens to every session and 2,743 once invoked, about $0.0002 per session on Opus 5.5. 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.
