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 | $0.00049 | $0.00703 |
| Opus 5 | $0.00024 | $0.00351 |
| Sonnet 5 | $0.00010 | $0.00141 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
min-specs 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 10d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Min Specs
Use this skill to define the smallest set of must-have conditions that make an action viable.
Method Notes
- Min Specs identify what is truly required, not a wish list.
- The method helps prevent overbuilding, over-negotiating, and pursuing deals that cannot work.
- A good Min Spec is binary enough to guide proceed / adjust / stop decisions.
Required Inputs
Collect or infer these inputs before execution:
- desired outcome
- proposed action, deal, solution, or change
- constraints and non-negotiables
- known failure modes
- stakeholder or customer requirements
If an input is missing, mark it as missing, state the assumption used, and add a validation action.
When Not To Use
Do not use when the user needs to rank attractive options rather than define viability. Use decision-matrix, weighted-scorecard, or wsjf-prioritization instead.
Step-by-Step Execution
| Step | Required input | How to execute | Output |
|---|---|---|---|
| Define success | Desired outcome, decision boundary. | State what must be true for the initiative to be considered successful. | Success definition. |
| List possible requirements | Stakeholder needs, constraints, risks, operating needs. | Create a broad list of candidate conditions. | Requirement pool. |
| Remove nice-to-haves | Candidate requirements, success definition. | Ask whether success fails without this condition. If not, move it to nice-to-have. | Trimmed requirements. |
| Convert to minimum specs | Must-have conditions. | Rewrite each condition as observable, testable, and binary where possible. | Min Specs list. |
| Define no-go criteria | Failure modes, risk tolerance, constraints. | State what would make the action non-viable or require redesign. | No-go list. |
| Link to next action | Current plan, validation access, owners. | Decide what to confirm first and what action is allowed before confirmation. | Decision gate. |

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.

min-specs is a skill published in the GitHub repository fzfclee/consulting-skills (4 stars, last pushed 22d ago), licensed Apache-2.0. It adds 49 tokens to every session and 703 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 2026-08-31.
