What it does

Vendor Management is an agent skill from cbrock84/headcount. Selects, contracts, and manages suppliers and vendors — requirements, evaluation, negotiation support, onboarding, performance management, and exit. Use this to choose a vendor, run a selection process, structure a service agreement's operational terms, manage an underperforming supplier, plan an exit or migration, or assess concentration and continuity risk.

Its SKILL.md is about 890 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`).

It sits in Business, Finance & HR, covering Vendor and procurement management. 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.

When your agent uses it

  • Tasks that involve Vendor and procurement management

Example prompts

  • “/vendor-management”

What it can do on your machine

Read from SKILL.md and the folder at commit 98d1c17. 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

Vendor Management loads about 889 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~889
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

description
Selects, contracts, and manages suppliers and vendors — requirements, evaluation, negotiation support, onboarding, performance management, and exit. Use this to choose a vendor, run a selection process, structure a service agreement's operational terms, manage an underperforming supplier, plan an exit or migration, or assess concentration and continuity risk.

Vendor management

Define requirements before looking at options

Written before any demo: what the vendor must do, the volume and service level required, what must integrate with what, and the constraints that are genuinely non-negotiable.

Requirements written after seeing a product describe that product. This is the most common way selections are decided before they are run.

Separate must-have from nice-to-have and weight them in advance. Weighting after scoring is how a preferred vendor wins a process designed to be objective.

Evaluating

  • Reference checks with customers of your size and use case. A reference running a tenth of your volume tells you nothing about whether it scales.
  • Test the actual failure modes, not the demo path. What happens when data is malformed, volume spikes, or an integration times out?
  • Assess the vendor, not just the product — financial stability, roadmap direction, support responsiveness, and whether you are a meaningful customer to them. Being a rounding error to your critical supplier is a risk in itself.
  • Total cost including your side: implementation, integration, migration, training, and the ongoing effort to operate it. License cost is frequently the smaller half.

Terms that matter operationally

Beyond the legal review: service levels with real remedies, support response times by severity, data export in a usable format on demand, notice periods that give you time to migrate, and price protection at renewal. The absence of the last two is what makes exit expensive later.

Managing

  • One named owner on your side. Vendors without an internal owner drift and renew automatically.
  • Review on a schedule against the service levels, with evidence. Vendor-supplied performance reports mark their own work.
  • Log issues. At renewal, a documented pattern is leverage; a recollection is not.
  • Diarize renewals well before the notice deadline. Auto-renewal past an unnoticed deadline is the most common and most avoidable vendor loss.

Concentration and exit

Know which vendors you could not operate without and what happens if one fails, is acquired, or triples its price. For each, know the exit path and roughly what it costs — an exit plan that has never been thought through is not an option, it is a hope.

Maintain your own copy of your data continuously where the vendor holds anything critical.

Sources

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.

Never

  • Sign before you know what leaving costs — data export, notice period, transition support.
  • Let the vendor write the requirements you evaluate them against.
  • Reach a renewal date without having started the renewal. The auto-renew clause is their leverage.
  • Concentrate a critical dependency on one vendor without saying so out loud and pricing the risk.
