What it does
Ijfw Summarize is an agent skill from FerroxLabs/ijfw. Generate optimized project context from codebase scan. Trigger: new project, no CLAUDE.md, /ijfw-summarize
Its SKILL.md is about 330 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 Agent Workflows, covering Agent instruction files. The repository describes itself as: IJFW — It Just Fcking Works. Ferrox Labs' local-first infrastructure for AI coding agents: shared memory, smart routing, multi-AI cross-audits, disciplined workflow. The licence is MIT.
When your agent uses it
- Tasks that involve Agent instruction files
Example prompts
- “/ijfw-summarize”
Requirements
- Docker
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read: package.json, tsconfig.json, Cargo.toml, pyproject.toml, go.mod, Dockerfile,
- Scan: directory structure (2 levels deep), test framework, linter config, CI config.
- Detect: language, framework, database, ORM, auth approach, deployment target.
- Identify: key directories, entry points, API route patterns, shared utilities.
What it can do on your machine
Read from SKILL.md and the folder at commit eda62f3. 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 markdown).
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
Ijfw Summarize loads about 326 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 91 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.
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
- Generate optimized project context from codebase scan. Trigger: new project, no CLAUDE.md, /ijfw-summarize
Scan the codebase and generate an optimized project context file.
Process
- Read: package.json, tsconfig.json, Cargo.toml, pyproject.toml, go.mod, Dockerfile, docker-compose.yml, .env.example, Makefile -- whatever exists.
- Scan: directory structure (2 levels deep), test framework, linter config, CI config.
- Detect: language, framework, database, ORM, auth approach, deployment target.
- Identify: key directories, entry points, API route patterns, shared utilities.
Output
Write a platform context file (CLAUDE.md, GEMINI.md, or equivalent) with:
# Project Context
Stack: <framework> / <language> / <database>
Architecture: <pattern -- monolith, microservices, serverless, etc.>
Entry: <main entry point(s)>
Tests: <framework + command to run>
Lint: <tool + command>
## Structure
<key directories and their purpose, 1 line each>
## Patterns
<established code patterns to follow, 1 line each>
## Key Files
<important files a new contributor should know about>Rules:
- Max 50 lines. This loads every session.
- No boilerplate explanations. Just facts.
- If uncertain about a pattern, omit it -- don't guess.
