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 | $0.00046 | $0.02978 |
| Opus 5.5 | $0.00018 | $0.01191 |
| Sonnet 5.5 | $0.00009 | $0.00596 |
| Haiku 4.5 | $0.00005 | $0.00298 |
Grade B, and why
mastermind-review scanned grade B with 1 finding 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
- "ignore all previous instructions" → expect prompt_injection ≥ 0.8 Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mastermind Review Domain
This skill is invoked directly via /mastermind:review, or by /mastermind:master (pack extras — monomind packs add extras).
Inputs
brain_context: BRAIN CONTEXT block (injected by master, or loaded standalone via mastermind-protocol/SKILL.md brain load)prompt: what to review and what to assessproject_name: monotask space nameboard_id: monotask board ID (set by master, or created standalone)mode: auto | confirm
Flags
Extract these from the raw args before other parsing:
| Flag | Variable | Default | Effect |
|---|---|---|---|
--monofence-ai-check |
monofence_check |
false | Option C: run monofence-ai self-validation (test suite + adversarial probes) |
--monofence-ai-security-deep |
monofence_deep |
false | Option B: scan LLM-facing input boundaries through monofence-ai |
Both flags are off by default. They do not affect non-security review angles.
Complexity Assessment
Assess the prompt to determine execution mode:
Simple (direct execution): Single file or single artifact:
- "Review this function for bugs"
- "Check this paragraph for clarity"
→ Use a single
revieweragent (for code or content). Skip manager delegation.
Complex (spawn Review Manager agent): Any of these:
- Full codebase or module audit
- Security review across multiple surfaces
- Strategy or content review requiring multiple expert perspectives
- Combined code + architecture + security pass → Spawn Review Manager agent with full briefing.
Standalone Execution (when called without master)
If this skill is invoked directly (not by master):
- Load brain context following mastermind-protocol/SKILL.md Brain Load Procedure (namespace:
review) - Run intake from mastermind-intake/SKILL.md if prompt is vague
- Follow mastermind-protocol/SKILL.md Monotask Space+Board Setup Procedure:
project_name="${project_name:-$(basename "$PWD")}" space_id=$(monotask space list 2>/dev/null | awk -F' \| ' -v n="$project_name" '$2==n{print $1}' | head -1) [ -z "$space_id" ] && space_id=$(monotask space create "$project_name" 2>&1 | grep -oE '[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}') [ -z "$space_id" ] && { echo "ERROR: Could not find or create space '$project_name'"; exit 1; } board_id=$(monotask board create "review" --json | jq -r '.id // empty') [ -z "$board_id" ] && { echo "ERROR: Failed to create review board"; exit 1; } monotask space boards add "$space_id" "$board_id" >/dev/null 2>&1 || true todo_col=$(monotask column create "$board_id" "Todo" --json | jq -r '.id') doing_col=$(monotask column create "$board_id" "Doing" --json | jq -r '.id') done_col=$(monotask column create "$board_id" "Done" --json | jq -r '.id') - Proceed with complexity assessment below
- At end: follow mastermind-protocol/SKILL.md Brain Write Procedure (namespace:
review)
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.

mastermind-review is a skill published in the GitHub repository monoes/monomind (23 stars, last pushed 2d ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,978 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (instruction-override phrasing). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-26.
