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 | $0.00026 | $0.01918 |
| Opus 5.5 | $0.00010 | $0.00767 |
| Sonnet 5.5 | $0.00005 | $0.00384 |
| Haiku 4.5 | $0.00003 | $0.00192 |
Grade A, and why
cross-functional-collaboration 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 2mo 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cross-functional Collaboration
Scope
Covers
- Leading a cross-functional initiative (Product/Engineering/Design/Data/Marketing/Ops/etc.)
- Turning “we’re misaligned” into explicit goals, roles, decisions, and operating cadence
- Reducing rework and conflict via shared artifacts (docs/prototypes) and clear decision rights
- Building trust through conflict norms and credit/recognition practices
When to use
- “We keep thrashing between PM/Eng/Design—set up a better way of working.”
- “Create a collaboration charter: roles, responsibilities, decision-making, and cadence.”
- “We need to work better with Engineering/Design/Data on .”
- “Our cross-functional project is slow due to unclear ownership and decisions.”
When NOT to use
- You need to define the underlying product problem first (use
problem-definition). - You need a full decision process for a single high-stakes decision (use
running-decision-processes). - The issue is primarily a performance or accountability problem with an individual (use
having-difficult-conversations). - You only need a timeline/milestone plan (use
managing-timelines). - You want to get buy-in from a specific stakeholder or exec on a one-time decision (use
stakeholder-alignment). - You want to build influence or set expectations with your own manager (use
managing-up). - You need to design recurring team ceremonies like standups, retros, or demos (use
team-rituals).
Inputs
Minimum required
- Initiative summary: what it is, why now, desired outcomes, and timeframe
- Functions/teams involved + key stakeholders (including any required subject matter experts)
- Current symptoms: where collaboration is breaking down (examples help)
- Constraints: deadlines, non-negotiables, policies/compliance, customer commitments
Missing-info strategy
- Ask up to 5 questions from references/INTAKE.md.
- If answers aren’t available, proceed with explicit assumptions and label 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.

cross-functional-collaboration is a skill published in the GitHub repository liqiongyu/lenny_skills_plus (53 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 26 tokens to every session and 1,918 once invoked, about $0.0001 per session on Opus 5.5. 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.
