create-context

create-context is a skill for Claude Code from shiggydoodah/skills. It costs 76 tokens per session (415 once invoked), scanned A, original, MIT.

A codebase documentation tool that creates a short context file for one directory and adds that directory to a root map. A monorepo is one repository containing multiple apps or packages, where finding the right context can be difficult.

In plain words
What is it for?
It helps document an app, package, subsystem, or directory by recording its purpose, architecture, flows, integrations, and operational concerns in CONTEXT.md and CONTEXT-MAP.md.
Why use it?
It gives future coding agents a focused summary of a subsystem without requiring them to inspect the whole repository first.

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

create-context 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 8d 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.

What it actually says

create-context

Creates one agent-only CONTEXT.md for a specific directory, then updates the root CONTEXT-MAP.md so future agents can find it quickly.

Use map-context for a repo-wide context map. Use create-context when the user points at one app, package, subsystem, or directory and wants a compressed brief for that area.

Invocation

/create-context              # create context for the current directory
/create-context apps/web     # create context for one target directory

Process

  1. Resolve the target - use the provided path, or the current directory if none is provided. Resolve the repo root with git rev-parse --show-toplevel; if that fails, use the current working directory.
  2. Inspect deeply - read enough source, tests, manifests, docs, and local configuration to understand the target's purpose, architecture, flows, integration points, and operational gotchas.
  3. Write one brief - create or replace CONTEXT.md at the target root. Do not create child contexts unless the user explicitly asks for them.
  4. Upsert the map - create or update CONTEXT-MAP.md at the repo root, preserving unrelated entries and replacing only the target entry.
  5. Report the result - summarize the target path, context file, map update, and any important limitations in what was inspected.

See REFERENCE.md for the required CONTEXT.md format, map entry rules, and compression guidelines.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
