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 | $0.00038 | $0.02102 |
| Opus 5 | $0.00019 | $0.01051 |
| Sonnet 5 | $0.00008 | $0.00420 |
| Haiku 4.5 | $0.00004 | $0.00210 |
Grade A, and why
scoping-cutting 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 9d 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.

Scoping & Cutting
Scope
Covers
- Converting a fuzzy initiative into a ship-able slice that fits a fixed time budget (“appetite”)
- Creating a cut list (what to drop/defer) with explicit trade-offs and rationale
- Defining an MVP as a hypothesis test (what you’re validating, not just “smaller”)
- Choosing a Minimum Lovable Slice (viable and emotionally resonant) instead of a “barely works” release
- Using Wizard-of-Oz / concierge approaches to validate value before building full automation
- Preventing scope creep via explicit non-goals + change control
When to use
- “Cut scope / descope this feature so we can ship by .”
- “Define an MVP for this initiative (what hypothesis are we testing?).”
- “We have 2–6 weeks; what can we ship that still matters?”
- “Scope creep is killing us; define what’s in/out and how changes happen.”
- “We need a minimum lovable version, not a compromised mess.”
When NOT to use
- You don’t yet know what problem you’re solving (use
problem-definition) - You’re choosing between many competing initiatives (use
prioritizing-roadmap) - You need a decision-ready PRD with requirements (use
writing-prds) or a build-ready design/tech spec (usewriting-specs-designs) - You’re setting long-term product strategy or vision (use
defining-product-vision) - You already have a scoped slice and need a timeline/milestone plan with stakeholder cadence (use
managing-timelines) - You’re planning the actual launch/release (rollout, rollback, monitoring) for an already-scoped feature (use
shipping-products)
Inputs
Minimum required
- The initiative/feature and the decision (ship vs defer vs stop) + target date or time budget
- Target user/segment + the core user journey you want to improve
- Success metric(s) + 2–5 guardrails (trust, quality, cost, latency, support load)
- Constraints and non-negotiables (legal/privacy, platform, dependencies, team size)
- Candidate scope items (bullets are fine) + known unknowns

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.

scoping-cutting is a skill published in the GitHub repository liqiongyu/lenny_skills_plus (52 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 38 tokens to every session and 2,102 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 2026-09-03.
