What it does

Buffer API is an agent skill from proflead/codex-skills-library. Manage Buffer content via the GraphQL API. Use when creating, scheduling, editing, or deleting posts, saving ideas, reading scheduled queues, or pulling post analytics. Not for general API debugging.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering GraphQL. It works with GraphQL. The repository describes itself as: Codex Skills Library is a curated library of reusable Codex skills for developers, individuals, and teams.

When your agent uses it

  • Reading scheduled queues
  • Pulling post analytics

Example prompts

  • “/buffer-api”

Requirements

  • A credential in BUFFER_API_KEY

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Get your organization ID (first time only)
  2. Get channel IDs for your target platforms
  3. Create or schedule the post using the relevant example below.
  4. Check the response — the mutation returns a union type. PostActionSuccess means it worked; MutationError carries the reason it failed…
  5. Edit or delete if needed using the post id returned in step 3.
  6. Pull analytics after the post publishes (metrics are refreshed daily; allow up to 24 hours after publish).

What it can do on your machine

Read from SKILL.md and the folder at commit a05260c. 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 (its code samples are graphql and json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • auth.buffer.com
    • api.buffer.com
    • publish.buffer.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • BUFFER_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Buffer API loads about 1.7k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 553 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 553 words (~1,698 tokens).

“Create, schedule, edit, and analyze social media content through Buffer's GraphQL API at https://api.buffer.com.”
