schedule-development-and-analysis

schedule-development-and-analysis is a skill for Claude Code from cbrock84/headcount. It costs 90 tokens per session (978 once invoked), scanned A, original, MIT.

A project-scheduling guide that models tasks, dependencies, delays, available time, resources, and the sequence that determines the finish date.

In plain words
What is it for?
It helps build, audit, update, and assess the risk of project schedules, including resource conflicts and progress against the original plan.
Why use it?
It replaces date lists that stop making sense when work changes with a plan whose dates follow the work. It also shows which delays actually threaten completion.

About the project

headcount is an organization of independently installable Claude Code plugins, each grouping skills for a department such as finance, security, or demand generation. Claude Code users install the departments they need and invoke their skills for specialized work; the catalogue entries are skills and related agent tooling from that organization.

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

schedule-development-and-analysis 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 3d 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.

Schedule development and analysis

A schedule is a model of how work connects. Most schedules in circulation are a list of dates someone typed, which looks the same in a status deck and behaves completely differently when anything moves.

Build it from logic, not from dates

Every task except the first and last should be connected to something. A task with a date and no predecessor is an assertion; a task with a predecessor is a plan, because when the predecessor moves the task moves with it and the schedule tells you so.

  • Finish-to-start is the default and covers most real dependencies.
  • Start-to-start and finish-to-finish describe overlapping work honestly and are worth using rather than faking the overlap with an earlier date.
  • Lags should represent something real — curing time, a notice period, a review window. A lag used to make dates line up is a hidden assumption.

Hard-coded date constraints are where schedules go to die. Each one severs the logic at that point, so slippage upstream stops propagating and the schedule keeps reporting a date it can no longer support.

Float is the information, and the critical path is the consequence

Float is how long a task can slip before it moves the end date. The critical path is the chain with none. Attention belongs there and almost nowhere else — expediting work with three weeks of float buys nothing and consumes the same management capacity.

Two readings worth taking regularly: near-critical chains, which become critical after one bad week and are where surprises come from, and negative float, which means the schedule is already telling you the date is impossible and someone has not looked.

Load resources before you believe the dates

A schedule that assumes the same three people work on five parallel tasks is fiction that will resolve itself as a delay. Load the named constraint — the one team, the one approver, the one environment — and level it. Leveling extends the schedule; that extension was always there, it was just unrecorded.

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.
