agent-feed: Skill for Claude Code

.agents/skills/project-architecture/SKILL.md

project-architecture is a skill for Claude Code, Codex from fqmyysjjd/agent-feed. It costs 29 tokens per session (198 once invoked), scanned A, original, MIT.

A project-architecture guide that must be used when understanding a codebase or deciding where work belongs. It directs the agent to the project's domain, contract, source-of-truth, structure, and architecture documents.

In plain words
What is it for?
Starting a project session, recovering after context compression, understanding how modules connect, and deciding which module should own a change. It is also for architecture, runtime, requirement, and structural decisions.
Why use it?
It reduces decisions based on guesses about responsibilities, requirements, or module boundaries. It helps distinguish architecture changes from domain rules, implementation details, and work that is out of scope.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fqmyysjjd/agent-feed's own configuration. It tells Claude Code and Codex how to work on agent-feed itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-feed configures →

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

project-architecture 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.

Project Architecture Skill

Required Use

Use this skill whenever you need to understand what the project is, why it exists, how modules connect, or where a responsibility belongs.

Required Reading

Expected Outcome

After using this skill, you should be able to explain the project target, owner module, relevant contract source, and whether a proposed change is architecture, domain, implementation detail, or out of scope.

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.
