What is ralphy-implement?

A coding workflow for implementing an OpenSpec change, where a proposed software change is described in files before it is built. It works through the task checklist, updates code and tests, and reports completion only after verification passes.

Use it when a repository has an active change under openspec/changes/ and you need to read its proposal, tasks, and specification updates, then implement and test them.

It gives an agent a repeatable way to turn a written specification into code while keeping implementation and tests aligned.

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	$0.00000	$0.00193
Opus 5.5	$0.00000	$0.00077
Sonnet 5.5	$0.00000	$0.00039
Haiku 4.5	$0.00000	$0.00019

Security

Grade A, and why

ralphy-implement 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 2mo 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

/ralphy-implement (Implement OpenSpec tasks)

You are implementing an OpenSpec change located under openspec/changes/<change-name>/.

Goal

Complete all tasks in tasks.md and satisfy the acceptance criteria from the spec scenarios.

Ralph loop compatibility

If this command is being executed in an iterative loop:

Make progress each iteration
Run tests frequently
Only declare success when verification passes

Steps

Identify the active change folder under openspec/changes/.
Read the change artifacts:
- proposal.md
- tasks.md
- spec deltas under specs/
Implement tasks in order:
- Update code
- Add/update tests
- Run tests
- Mark tasks complete ONLY when verified

Completion promise

Only output this exact text when ALL tasks are complete and tests pass:

TASK_COMPLETE

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.

ralphy-implement is a command published in the GitHub repository wenqingyu/ralphy-openspec (175 stars, last pushed 9mo ago), licensed BSD-3-Clause. It costs nothing until one of its globs matches a file; then it loads 193 tokens. 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.
