Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00029 | $0.01445 |
| Opus 5 | $0.00015 | $0.00723 |
| Sonnet 5 | $0.00006 | $0.00289 |
| Haiku 4.5 | $0.00003 | $0.00145 |
Grade A, and why
create-team-skill 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 yesterday.
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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create a Team skill
Create a skill another agent can select cheaply and follow without missing a contract.
Six laws
- Assert; do not argue. State the rule. Keep one
**Why:**line only when it changes behavior in an unlisted case. - Give the invariant, not the case list. Keep enumerations only when each member is a distinct fact, command, exception, or security boundary.
- Single source of truth. Define shared logic and rules once. Consumers name the skill or invoke the shared script.
- SKILL.md is a router. Put conditional procedures, prompt templates, schemas, and long command recipes in
references/or executable logic inscripts/. - The description is a trigger. Write
<what it does>. <when to trigger>.; keep it at most 200 characters, or 150 for methodology. - Tests pin contracts, not wording. Assertions may pin a command, number, name, or path. Never pin a sentence or heading.
Preserve every command, number, path, name, authorization boundary, untrusted-input rule, fail-closed gate, and producer/reviewer separation rule during rewrites.
Budgets
| Tier | Frontmatter | SKILL.md budget |
|---|---|---|
| Principle | name starts principle- |
25 lines |
| Methodology | user-invocable: false |
80 lines |
| Entry point | otherwise | 150 lines |
An overage requires a current entry in SKILL_BUDGET_REASONS in tests/skill-budget.test.ts, keyed by skill and stating the exact line count and reason. A budget is a ceiling, not a target.
Classify
- A principle states one cross-cutting, observable invariant, is not better enforced mechanically, has a current consumer, uses
user-invocable: false, and carries noeffort. Name itprinciple-<name>and keep each rule to one imperative line. - Methodology is reusable reference material. Set
user-invocable: false; never expose it directly as a slash command. - An entry point is a user action. Leave
user-invocableunset. If methodology also needs a command, add a separate front door such ascode-reviewoverreviewing-code. - Use
disable-model-invocation: trueonly for an explicit-only entry point with a recorded reason.
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.

create-team-skill is a skill published in the GitHub repository bostonaholic/team (11 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 1,445 once invoked, about $0.0001 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.
