fusebase-flow: Instructions file for GitHub Copilot

.github/instructions/validation.instructions.md

fusebase-flow validation.instructions.md is an instructions file for GitHub Copilot from fusebase-dev/fusebase-flow. It costs 436 tokens per session, scanned A, original, MIT.

A set of validation instructions for checking software changes and post-deployment behaviour. It defines complete gate reports, repeated reproduction of failures, and smoke tests—small checks of the user-visible result after release.

In plain words
What is it for?
Use it to review changes against a defined gate, reproduce reported failures three times, run numbered smoke prompts, inspect the real diagnostic surface, and save test evidence.
Why use it?
It helps avoid fixing a one-off or non-repeatable failure and prevents incomplete test reports from being treated as complete. It also keeps evidence of post-deployment checks in a known location.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is fusebase-dev/fusebase-flow's own configuration. It tells GitHub Copilot how to work on fusebase-flow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fusebase-flow configures →

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

fusebase-flow validation.instructions.md 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 today.

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

Fusebase Flow — validation & QA instructions for GitHub Copilot / VS Code

Apply when running gate checks, reviewing diffs against the gate contract, or verifying smoke prompts.

Gate report (AI Developer-side)

Required fields are canonical in policies/gate-contracts.yml: gate_report (machine schema); the producer template is templates/gate-report.md. Do not restate the field list.

If any field is missing, redirect: "Gate report missing . Per FR-05, complete reports only. Re-run."

Reproducibility before fix (FR-10)

When the operator describes a single observed failure:

  1. Don't draft a fix immediately.
  2. Reproduce 3 times under the same conditions.
  3. Outcomes:
    • 3/3 reproduce → systemic; draft fix.
    • 1/3 or 2/3 → likely model variance / non-determinism; document and recommend no-op close.
    • 0/3 → close as no-op-needed.

Smoke prompts (post-deploy)

When verification-gate.md defines numbered S1..Sn:

  • Follow flow-skills/smoke-testing/SKILL.md.
  • Verify the operator-visible outcome, not only supporting checks.
  • Inspect the ground-truth diagnostic surface named by S.
  • Persist evidence to docs/tmp/handoff/<date>-<slug>-smoke/.
  • Compute pass ratio against the gate contract threshold.
  • If below threshold or end-to-end smoke is not feasible, do NOT mark spec DONE; surface failure or PENDING-OPERATOR-SMOKE with concrete S<n> observed Y, expected Z / missing prerequisite.

What this scope does NOT do

  • Approve deploy (that's the release-deploy-reporting skill)
  • Auto-fix lint / typecheck errors — surface them
  • Skip reproducibility-before-fix (FR-10)
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.
