What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
New Manager First 90 Days loads about 1.3k tokens when it runs. Until then it costs about 143 tokens; SKILL.md has 616 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

New Manager: First 90 Days
The jump to managing is a role change, not a promotion for doing more of the same — and most first-time managers stumble by either changing everything on day one or staying an individual contributor with a title. This gives a phased first-90-days plan: earn trust and learn first, then set direction, then adjust — plus how to handle the 1:1s, delegation, and hard conversations that define the job.
What This Skill Produces
- A phased 90-day plan — listen & learn (first weeks) → set direction (mid) → adjust & build (later), instead of changing everything at once
- First 1:1s — how to run them to build trust and understand each person (their goals, working style, and what they need from you)
- The mindset shift — moving from doer to enabler: your output is now the team's output
- Trap avoidance — the classic first-time mistakes (doing the work yourself, changing too fast, avoiding difficult conversations, playing favorites)
- Early wins — credibility-building moves that help the team without overstepping
- A read on the situation — inheriting a team vs. building one, peers-now-reports, or a struggling team
Required Inputs
Ask for these if not provided:
- The situation — inherited team, new team, promoted over former peers, or a turnaround
- The team — size, and what you know about how it's doing
- Your background — first-time manager or experienced, and your relationship to the team
- The context — org expectations, any pressing issues
- Your worry — what you're most unsure about
Framework: Learn, Then Lead
- Listen before you change. Spend the early weeks understanding the team, the work, and the context before making changes — early sweeping changes without understanding destroy trust.
- Invest in 1:1s. Use first 1:1s to learn each person's goals, strengths, working style, and needs — relationships are the foundation of everything else.
- Make the mindset shift. Your job is now to enable the team, not to be the top individual contributor — resist doing the work yourself; delegate and develop.
- Set direction once you understand. After learning, clarify priorities, expectations, and how the team will work — then adjust based on what you see.
- Don't dodge the hard stuff. Address underperformance and tensions kindly but directly; avoiding difficult conversations early is a trap that compounds.
- Bank early, appropriate wins. Small improvements and removing blockers build credibility without overstepping your still-forming understanding.

Output Format
First 90 days: [situation] · team [size] · [first-time?]
Situation read: [inherited/new/former-peers/turnaround → what it means]. Phase 1 (learn, ~weeks 1–4): listen · first 1:1s · understand work/context · no big changes yet. First 1:1s — ask: [goals · working style · what they need from you · what's working/not]. Phase 2 (direction, ~weeks 5–8): clarify priorities/expectations · how the team works. Phase 3 (adjust & build, ~weeks 9–12): refine · develop people · early wins. Mindset shift: doer → enabler (your output = the team's). Avoid: doing it all yourself · changing too fast · dodging hard conversations · favoritism. Early wins: [remove a blocker · a small improvement].
Quality Checks
- Plan is phased (learn → direct → adjust), not change-everything-now
- Includes how to run trust-building first 1:1s
- Names the doer→enabler mindset shift and delegation
- Warns against the classic first-time-manager traps
- Includes appropriate early wins
- Tailored to the situation (inherited/peers/turnaround)
Anti-Patterns
- Changing everything on day one before understanding.
- Staying an IC with a manager title (won't delegate).
- Skipping real 1:1s and relationship-building.
- Avoiding underperformance/tension early.
- Favoritism or trying to be everyone's friend over being fair.
Example Trigger Phrases
- "I just became a manager for the first time — help me plan my first 90 days."
- "How do I run my first 1:1s with my new team?"
- "I got promoted over my former peers — how do I handle it?"
- "I'm a new manager and keep doing all the work myself. Help."
- "What are the biggest mistakes new managers make and how do I avoid them?"
