A developer-agent instruction that requires test-driven development, or TDD: writing tests before the code they check. It tells the agent to use a separate subagent and follow project task instructions.

Use it to implement a feature from a requirements folder, review existing feedback, update task files, and run tests and linting.

It creates a repeatable process for implementing features while checking behavior throughout the work.

How entireio/cli configures Claude Code

About the project

Entire CLI connects AI coding-agent sessions to Git so prompts, responses, files, tool calls, and checkpoints become a searchable record alongside commits. Developers and teams use it to understand why code changed, resume earlier sessions, keep agent context out of Git history, and support traceability. The catalogue includes commands, hooks, skills, agents, and plugins for the Entire workflow.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00015	$0.00238
Opus 5.5	$0.00006	$0.00095
Sonnet 5.5	$0.00003	$0.00048
Haiku 4.5	$0.00002	$0.00024

Security

Grade A, and why

dev 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 1mo 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

ACTION REQUIRED: Spawn a subagent using the Task tool.

Do NOT implement code directly. Instead, immediately call the Task tool with:

Task(
  subagent_type: "general-purpose",
  description: "Developer implementing [feature]",
  prompt: "
    Read and follow the instructions in .claude/agents/dev.md

    Requirements folder: $ARGUMENTS

    Your task:
    1. Read .claude/agents/dev.md for your role and process
    2. Read $ARGUMENTS/README.md for requirements
    3. Check for existing task files and review files in $ARGUMENTS/
    4. If review-NN.md exists, address that feedback first
    5. Create/update task breakdown files
    6. Implement using TDD (test first, then code)
    7. Run tests and linting after each step
    8. Report what you built when done

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.

dev is a command published in the GitHub repository entireio/cli (5,181 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 238 once invoked, about $0.0001 per session on Opus 5.5. 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.
