dev-flow

dev-flow is a skill for Claude Code, Codex from vakovalskii/ontoship. It costs 86 tokens per session (814 once invoked), scanned A, original, MIT.

A step-by-step development process for taking a software feature or bug fix from research to production. It uses written specifications, separate Git workspaces, testing, review, and staged deployment.

In plain words
What is it for?
Use it to investigate a problem, plan tasks, write a durable specification, implement the change in an isolated Git worktree, run tests, get an independent review, and ship through development to production.
Why use it?
It reduces guesswork and keeps unfinished changes away from the main codebase. Each change has a clear completion rule and passes checks before release.

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

dev-flow 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dev-flow — from idea to production

A battle-tested loop for shipping with an AI agent: a feature reaches production in roughly 40 minutes to 2 hours. The spec is plain markdown written via the KB skills, the work happens in an isolated git worktree, and only green reaches prod. The KB (see kb-curate) is the carrier of knowledge — onboarding, hand-off and scaling all start from it, not from the code.

The loop

  1. Research — understand from facts, not guesses: read logs, traces, and the code itself. Reproduce before fixing.
  2. Tasks — turn the research into a list of tracked tasks with dependencies. Nothing gets lost.
  3. Goal — crystallize one clear goal and the "done" criterion from those tasks.
  4. Spec — write it as markdown in the KB via kb-curate (ontology: node_type, frontmatter, typed links links.documents: [src/…]). The spec is durable knowledge, not a throwaway ticket — searchable, linkable, graphable.
  5. Isolate — work in a dedicated git worktree: main stays untouched, parallel agents don't collide, and rollback is just dropping the worktree.
  6. Implement — code to the spec inside the worktree; keep doc↔code linked (implemented_by).
  7. Tests — write/adjust unit + E2E for the feature. The test is part of the feature, not an afterthought.
  8. Independent review — run an independent model (e.g. Codex CLI, read-only) over the diff for logic and security bugs before rollout. A second model catches what the author's model misses — on a real production codebase this pass caught 191 bugs before they reached prod.
  9. Dev-tests — open an MR with the commits into the dev branch; run the full suite there. Red → fix in the worktree, don't merge.
  10. Prod-tests — E2E/smoke against the real prod contour, not only mocks or dev. Verify behaviour where users live.
  11. Ship — merge dev → main and deploy (build the new image before stopping the old container, then poll the healthcheck to measure real downtime).

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-flow is a skill published in the GitHub repository vakovalskii/ontoship (76 stars, last pushed 9d ago), licensed MIT. It adds 86 tokens to every session and 814 once invoked, about $0.0004 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.
