build-recovery

build-recovery is a skill for Claude Code, Codex from QuantumByteOSS/quantumbyte. It costs 67 tokens per session (384 once invoked), scanned A, original, Apache-2.0.

Guidance for managing long-running builds and explaining build failures while an application is being generated.

In plain words
What is it for?
Use it to narrate concrete build progress, identify whether a failure is transient or caused by the requested scope, and choose an appropriate retry or refinement.
Why use it?
It keeps the user informed during waits and replaces vague failure messages with a known cause and a practical recovery path when possible.

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

build-recovery 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

Build-recovery — wait management + failure

The build is the moment the user shifts from evaluating to delighted-or-disappointed. A silent wait or a generic error is where the "it's actually building" belief dies.

While it runs (wait management)

Narrate the next concrete piece coming online — short, present-tense, plural: "wiring the booking calendar… setting up reminders… deploying." Never show "no active activity" or an opaque spinner during the most exciting moment. Tie the narration to their app's real pieces, not generic build steps.

When it fails

A generic "something went wrong, try again" is a belief-erosion event. An honest, specific narration is a belief-reinforcement event — a system that sees its own failure and fixes it is the strongest trust signal there is.

  1. Name it with the cause if you have it: "the database setup hit a configuration edge case." If you don't: "the build stopped partway — I'm not sure why yet, here's what I can try." Never blame the user.
  2. Offer the real paths, matched to the cause:
    • transient → simple retry: rebuild directly.
    • scope/spec issue → retry with refined inputs (back to naming/scope, then rebuild).
    • structural mismatch revealed → this may actually be a disqualification; route there.
  3. Keep the user's momentum: one short honest line, one clear next move, no doc-length apology.
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.
