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 | $0.00038 | $0.01558 |
| Opus 5 | $0.00019 | $0.00779 |
| Sonnet 5 | $0.00008 | $0.00312 |
| Haiku 4.5 | $0.00004 | $0.00156 |
Grade A, and why
governor 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 3d 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.

🏛️ Governor — Portfolio Governance
Enforce tier-appropriate complexity. Prevent over-engineering the #1 waste of time in AI-assisted development.
Activation
When this skill activates, output:
🏛️ Governor — Checking project tier constraints...
Then execute the protocol below.
Context Guard
| Context | Status | Priority |
|---|---|---|
| User starts a new project ("new project", "init", "scaffold") | ACTIVE — assign tier | P1 |
| User asks "what tier", "what's allowed", "scope check" | ACTIVE — report current tier constraints | P1 |
| User proposes work that exceeds current tier | ACTIVE — flag and advise | P2 |
| User is executing work within tier constraints | DORMANT — don't interrupt | — |
| User explicitly overrides ("I know, do it anyway") | DORMANT — user has authority | — |
Anti-Rationalization
If you're thinking any of these, STOP — you're about to let scope creep happen:
| You're thinking... | Reality |
|---|---|
| "Adding tests is always good practice" | Not for prototypes. Tests for throwaway code waste time. |
| "This needs proper auth" | Single-user tools don't need auth. Add it when there are users. |
| "Let me add CI/CD while I'm at it" | CI/CD for a prototype is gold-plating. Ship first. |
| "Error handling should be comprehensive" | Prototype error handling = crash and log. That's it. |
| "I should add monitoring" | < 10 users? Console.log is your monitoring. |
| "This should be configurable" | Hardcode it. Make it configurable when someone asks. |
Protocol
Step 1: Determine Project Tier
Ask or infer the project tier from context:
| Tier | Description | Effort Allocation |
|---|---|---|
| Prototype | Exploring an idea. May be thrown away. | Minimal — working code only |
| MVP | Validated idea, building for first users. | Moderate — basic quality gates |
| Production | Serving real users, needs reliability. | Full — complete quality stack |
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.

governor is a skill published in the GitHub repository cwinvestments/memstack (417 stars, last pushed 6d ago), licensed MIT. It adds 38 tokens to every session and 1,558 once invoked, about $0.0002 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 2026-08-30.

plan-ceo-review
CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Four modes: SCOPE EXPANSION (dream big), SELECTIVE EXPANSION (hold scope + cherry-pick expansions), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials). Use when…
ship
Ship workflow: detect + merge base branch, run tests, review diff, bump VERSION, update CHANGELOG, commit, push, and create a PR. Use for an explicit /ship invocation or when the user requests the full ship, release, or deploy workflow. For an ordinary commit, push, or pull-request publishing request, use the built-in…
design-review
Designer's eye QA: finds visual inconsistency, spacing issues, hierarchy problems, AI slop patterns, and slow interactions — then fixes them. Iteratively fixes issues in source code, committing each fix atomically and re-verifying with before/after screenshots. For plan-mode design review (before implementation), use…
plan-eng-review
Eng manager-mode plan review. Lock in the execution plan — architecture, data flow, diagrams, edge cases, test coverage, performance. Walks through issues interactively with opinionated recommendations. Use when asked to "review the architecture", "engineering review", or "lock in the plan". Proactively suggest when…
autoplan
Auto-review pipeline — reads the full CEO, design, eng, and DX review skills from disk and runs them sequentially with auto-decisions using 6 decision principles. Surfaces taste decisions (close approaches, borderline scope, codex disagreements) at a final approval gate. One command, fully reviewed plan out. Use when…
retro
Weekly engineering retrospective. Analyzes commit history, work patterns, and code quality metrics with persistent history and trend tracking. Team-aware: breaks down per-person contributions with praise and growth areas. Use when asked to "weekly retro", "what did we ship", or "engineering retrospective". Proactively…
