onboarding-and-offboardingDesigns the joining and leaving experience — first-day readiness, ramp to productivity, knowledge capture, and clean exits.
Onboarding And Offboarding is an agent skill from cbrock84/headcount. Designs the joining and leaving experience — first-day readiness, ramp to productivity, knowledge capture, and clean exits. Use this to design or fix onboarding, shorten time to productivity, structure a leaver process, capture knowledge before someone leaves, or coordinate the access and asset steps around a joiner or leaver.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sources.md`).
The repository describes itself as: An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs… The licence is MIT.
Read from SKILL.md and the folder at commit 98d1c17. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Onboarding And Offboarding loads about 1k tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 563 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.
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.

This skill also uses 1 other file; get the full folder from GitHub.Both ends are cross-functional processes that fail at the handoffs. The failures are predictable, which means they are preventable by design rather than by diligence.
Everything procurable in advance should be ready: accounts, hardware, access, a first assignment, and a named person responsible for the human side. A first day spent waiting for a laptop is a permanent first impression, and it is entirely a coordination failure.
The identity and equipment steps are executed by
it-operations:identity-lifecycle-administration and it-operations:endpoint-management; access
policy — what a role should be entitled to — belongs to security:access-and-identity. This skill
owns the sequence and whether it actually completed.
Separate the three things a new person is learning, because they need different support:
The third is the one nobody plans and the one that most determines how quickly someone becomes useful. Make introductions explicit assignments rather than leaving them to chance and extroversion.
Give real work early, scoped to succeed. A meaningful contribution in the first fortnight does more for confidence and belonging than any amount of orientation material.
Check in at deliberate intervals — a week, a month, a quarter — with the question phrased so problems can surface. "What has been more confusing than it should be?" gets an answer; "how's it going?" does not.
Knowledge capture has to precede the access cutoff, which means starting on the day notice is given, not the day before departure.
Prioritize what is genuinely undocumented and only in one head: the systems they alone maintain, the relationships they hold, the decisions whose reasoning exists nowhere. Ask directly — "what will break, and who will not know why?" — because they know and will usually say.
Then run the mechanical steps as a checklist with an owner: access revoked across every system including those outside single sign-on, assets returned, delegations and approvals reassigned, and handover confirmed by the person receiving it rather than by the person leaving.
Exit conversations produce candid information that is unavailable any other way, and it is routinely
collected and never used. Aggregate themes over time and look by manager and by team; a single exit
is an anecdote, a pattern across four is a finding for people:chief-human-resources-officer.
references/sources.md in this skill lists the outside authorities that settle the questions
here — what each one is authoritative for, and what you may do with it. Check them before
answering on anything they cover, and cite what you used. Most are free to read and not free
to reproduce; the use note on each is binding.
HRIS as the record of who works here and when they started or left: Workday, BambooHR, Rippling, HiBob, Gusto, ADP, and similar.
Onboarding workflow: the HRIS's own, or Sapling, Enboarder, or a checklist in the ticketing system, and similar.
Offboarding has to reach identity, devices, and payroll the same day. Whatever the tools, one owner runs the checklist end to end. Split ownership is how accounts stay live.

Run `npx skills add cbrock84/headcount --skill onboarding-and-offboarding -a claude-code`. Or copy the skill folder (plugins/people/skills/onboarding-and-offboarding in cbrock84/headcount) into .claude/skills/onboarding-and-offboarding in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cbrock84/headcount --skill onboarding-and-offboarding -a codex`. Or copy the skill folder (plugins/people/skills/onboarding-and-offboarding in cbrock84/headcount) into .agents/skills/onboarding-and-offboarding in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cbrock84/headcount --skill onboarding-and-offboarding -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/onboarding-and-offboarding, .gemini/skills/onboarding-and-offboarding, .github/skills/onboarding-and-offboarding and .opencode/skills/onboarding-and-offboarding in your project.
SKILL.md names no scripts, command-line tools or credentials: Onboarding And Offboarding is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Onboarding And Offboarding is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1k tokens (SKILL.md is roughly 4.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 231 tokens, read only when the agent opens those files.
