A guidance skill for setting realistic project deadlines and improving estimates. It covers different causes of schedule pressure, such as unclear scope, distractions, estimation errors, or stakeholder expectations.

In plain words
What is it for?
Use it to plan phases, assess deadline risks, choose a suitable delivery approach, and build healthier scheduling habits.
Why use it?
It helps turn vague delivery pressure into manageable commitments and exposes when a date or scope is unrealistic.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

managing-timelines 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.

Managing Timelines

Help the user set and hit realistic project timelines using approaches from 13 product leaders.

How to Help

When the user asks for help with timelines:

  1. Understand the context - Ask about the nature of the deadline (external commitment, internal target, manufactured milestone), the stage of the work, and what's driving the timeline pressure
  2. Diagnose the problem - Determine if this is an estimation issue, a scoping issue, a distraction issue, or unrealistic stakeholder expectations
  3. Apply the right framework - Help them use phase-based commitments, hill charts, or early shipping strategies depending on their situation
  4. Build healthy habits - Guide them toward sustainable timeline practices rather than one-time fixes

Core Principles

Treat real deadlines as P0 - nothing else matters

Nan Yu: "The only way to make deadlines real is to take them so seriously that they are basically like a P0 problem, and everything else has to not matter in comparison." Don't have too many deadlines. Reserve them for critical external events and protect the team from all other distractions once set.

Commit to phases, not distant delivery dates

Annie Pearl: "We've moved to committing to dates that are within our control. We can commit to a discovery effort... versus making a commitment around a project six months out when we haven't done enough discovery." Break work into Discovery, Solutioning, Build, and Launch. Only provide engineering delivery dates once solutioning is complete.

Ship early, iterate with remaining time

Nan Yu: "We do almost no estimating. What we do is ship as early as we can. If by 10% of the time you have a working thing, you can spend the rest deciding whether to iterate or polish." Focus on getting to a "yes or no" shippable state quickly rather than front-loading estimation.

Use hill charts to track uncertainty

Jason Fried: "A project's more like a hill. The left side means you're still figuring it out. Once work gets to the top, it's downhill from there - pure execution." Visualize work as a hill where left side is discovery and right side is execution. Items stuck on the uphill side are high-risk for missing deadlines.

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.
