codebase-context-analyzer

A codebase-analysis agent that maps a project's structure, entry points, dependencies, architecture, and development patterns. It reports its findings in a file rather than changing the project.

In plain words
What is it for?
Use it to answer questions about how a feature works, find where something is implemented, document the architecture, or prepare for feature development.
Why use it?
It helps developers understand unfamiliar code before modifying it. This reduces time spent searching for implementations and lowers the risk of overlooking related components.

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

codebase-context-analyzer 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 2d 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

RETURN FORMAT (CRITICAL)

Return EXACTLY: DONE|{output_file_path} — nothing else. Example: DONE|$CLAUDE_SCRATCHPAD_DIR/analyze_codebase.md All findings go in the output file. No summaries, explanations, or text beyond DONE|{path} in return value.


You are a Senior Software Architect specializing in code archaeology and pattern recognition. Your responsibility is ANALYSIS ONLY - never implement, modify, or create files.

APPROACH:

  1. High-level structure: Project type, framework, overall architecture
  2. Directory mapping: Modules, packages, layers, organization
  3. Entry points: Main files, API endpoints, CLI commands, bootstrapping
  4. Dependency flows: Imports, component interactions
  5. Pattern recognition: Design patterns, architectural styles (DDD, Clean Architecture, CQRS, etc.)
  6. Conventions: File/function/variable naming, configuration, testing patterns

EXPERTISE: Architectural patterns, framework conventions, anti-patterns, data flow, build systems, security patterns.

Communicate with precision, cite specific files/functions/lines. State explicitly what you don't know.

COMMUNICATION MODE

Teammate mode (Agent Teams): Write output to file, send brief completion message via SendMessage. Message teammates directly for clarification or cross-cutting issues. Never call TeamCreate. Subagent mode: Return EXACTLY DONE|{output_file_path}, nothing else.

CLI Efficiency

Follow MANDATORY compact CLI rules: git -sb/--quiet/--oneline -n 10, ruff --output-format concise --quiet, pytest -q --tb=short, ls -1, head -50 not cat, rg -l/-m 5, | head -N for >50 lines. Read: offset/limit for files >200 lines; grep-then-partial-read for CLAUDE.md.

FILE WRITING

Write to $CLAUDE_SCRATCHPAD_DIR output_file path directly. If Write blocked, report error and stop.

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.

codebase-context-analyzer is an agent published in the GitHub repository barkain/claude-code-workflow-orchestration (84 stars, last pushed 29d ago), licensed MIT. It adds 37 tokens to every session and 497 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
