blitz

blitz is a skill for Claude Code, Codex from samibs/skillfoundry. It costs 9 tokens per session (377 once invoked), scanned A, original, MIT.

A shortcut for running the Go workflow in semi-automatic mode with parallel work and TDD. TDD, or test-driven development, means writing tests as part of the implementation process; parallel work runs independent stories at the same time.

In plain words
What is it for?
Use it with validated PRDs whose stories are mostly independent, especially when at least two can run in parallel. It also supports a dry run that previews the wave plan without executing it.
Why use it?
It speeds up well-defined development plans by grouping independent tasks into dependency-ordered waves and applying automatic remediation. Parallel execution is not useful when stories depend heavily on one another.

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

blitz 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

/blitz - Blitz Mode Commander

/blitz is a thin alias for /go --mode=semi-auto --parallel --tdd. It runs the full /go pipeline at maximum speed: semi-auto remediation + parallel wave execution + TDD enforcement. Blitz is for well-defined PRDs with independent stories.

Persona: See agents/fixer-orchestrator.md for auto-remediation and agents/_parallel-dispatch.md for wave planning. Reflection Protocol: See agents/_reflection-protocol.md.


Dispatch

/blitz [args] → /go --mode=semi-auto --parallel --tdd [args] with full argument passthrough.

/blitz genesis/auth.md   →  /go --mode=semi-auto --parallel --tdd genesis/auth.md
/blitz --dry-run         →  preview the wave plan without executing

When blitz applies

Blitz only adds value when stories can run in parallel. Readiness check — all must hold, or use /gosm instead:

  • The PRD is well-defined and validated
  • Stories are mostly independent (wave planning needs independence)
  • At least 2 stories are independent — otherwise parallelism has no value

Wave planning is defined in agents/_parallel-dispatch.md: stories are grouped into dependency-ordered waves, same-wave stories are checked for file-overlap conflicts, and all stories in a wave are dispatched simultaneously (RED→GREEN→REFACTOR under TDD). Run --dry-run to preview the wave plan before executing. Everything else — phases, Anvil gates, delivery audit — is /go's behavior unchanged.

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.
