agent-smith CLAUDE.md

agent-smith CLAUDE.md is an instructions file for Claude Code from holgerleichsenring/agent-smith. It costs 2,302 tokens per session, scanned A, original, MIT.

A set of instructions for agent-smith, a tool that helps AI agents work through software projects in defined phases. It tells the agent which project notes, rules, decisions, and past experiences to read.

In plain words
What is it for?
Guiding agent-smith through a repository, following project-specific coding rules, tracking active work, and recalling relevant past lessons.
Why use it?
It prevents the agent from missing important project context or ignoring earlier decisions. It also gives the work a consistent structure across phases.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

agent-smith CLAUDE.md 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 yesterday.

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.

Context Files (read in this order)

  1. Every .agentsmith/contexts/<name>/context.yaml (glob contexts/*/context.yaml) — architecture, stack, integrations, phase status PER stack
  2. Every .agentsmith/contexts/<name>/principles.md — code quality rules per stack (ALWAYS follow)
  3. .agentsmith/phases/active/*.yaml — spec for the phase being implemented (its applies_to: names the dominant context)
  4. .agentsmith/decisions/*.yaml — past decisions, one YAML per phase or run (read the active phase's file and its requires: chain)
  5. .agentsmith/memory/MEMORY.md — the experiential-memory index, one line per recorded fact; recall detail from .agentsmith/memory/<name>.md on demand when a line touches your task

Phase Directory Structure

.agentsmith/phases/
  done/       # completed phases (historical reference)
  active/     # phase currently being worked on
  planned/    # upcoming phases with requirements

Experiential Memory (remember / recall)

.agentsmith/memory/ holds typed Markdown facts: one file per memory with frontmatter name (slug = filename), description (one line), and metadata.type (feedback = how the operator wants the agent to work, ratification required; project = goals/constraints/state not derivable from code or git; reference = external pointers). MEMORY.md is the index — one line per memory, content never in the index.

  • Recall before re-deriving: when the index hints at a fact you are about to work out from scratch, read the entry file instead.
  • Remember sparingly: store what code and git cannot already tell the next agent — one fact per file; check the index for an existing entry and update rather than duplicate; delete a memory that turns out wrong; link related memories as [[slug]] (a cited slug requires its committed definition). A new or changed feedback entry is a PROPOSAL until the operator ratifies it.
  • Memory vs decision: a decision records a CHOICE (decisions/); a memory records a transferable FACT or RULE. Never duplicate one into the other.

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.
