What it does

Working With Skills is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Best practices for agents managing PostHog skills via the MCP skill- tools — how to discover, read, create, update, and refactor skills efficiently, especially large skills with many bundled files. Use whenever you are about to call any skill- tool, asked to author or edit a shared skill, or troubleshoot why a skill write was rejected. Also use when asked what skills are good for or how to shape one (project hub, runbook, catalog, handover, daily driver). Pairs with skills-store (which covers the raw tool…

Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/skill-patterns.md`).

It sits in DevOps & Cloud, covering Runbooks and postmortems. It works with PostHog and Model Context Protocol. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…

Workflow steps

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

Progressive disclosure is non-negotiable. Lists return descriptions, get
Pick the smallest write primitive that does the job. A targeted edits
Reads are cheap; concurrent overwrites are not. Always have a recent
Authoring follows the Agent Skills spec.

What it can do on your machine

Read from SKILL.md and the folder at commit c012c8d. 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 json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- agentskills.io
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

Working With Skills loads about 4.4k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 155 tokens; SKILL.md has 1,987 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~155
When it runs · the whole SKILL.md, loaded when a task matches: ~4.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~7.8k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,987 words (~4,378 tokens).

“This skill teaches agents how to use the skill-* MCP tools well — minimum context, minimum round-trips, minimum mistakes. If you are not yet familiar with the tool surface itself, read the skills-store skill first for the catalog. This document…”
