gate

A verification checklist for coding work that requires fresh command output before saying a change is complete, fixed, or passing.

In plain words
What is it for?
Checking tests, linters, builds, bug fixes, and requirements before committing changes or opening a pull request.
Why use it?
It prevents developers from treating assumptions or old test results as proof that the code works.

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

gate 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 2d 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.

Verification Before Completion

Core Principle

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE.
Evidence before claims, always.
Violating the letter of this rule is violating the spirit of this rule.

The Iron Law

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

If you haven't run the verification command in this message, you cannot claim it passes.

The Gate Function

BEFORE claiming any status or expressing satisfaction:

1. IDENTIFY: What command proves this claim?
2. RUN: Execute the FULL command (fresh, complete)
3. READ: Full output, check exit code, count failures
4. VERIFY: Does output confirm the claim?
   - If NO: State actual status with evidence
   - If YES: State claim WITH evidence
5. ONLY THEN: Make the claim

Skip any step = lying, not verifying

Common Failures

Claim Requires Not Sufficient
Tests pass Test command output: 0 failures Previous run, "should pass"
Linter clean Linter output: 0 errors Partial check
Build succeeds Build command: exit 0 Linter passing
Bug fixed Test original symptom: passes Code changed, assumed fixed
Requirements met Line-by-line checklist Tests passing

Red Flags - STOP

  • Using "should", "probably", "seems to"
  • Expressing satisfaction before verification
  • About to commit/push/PR without verification
  • Trusting agent success reports
  • Relying on partial verification
  • Thinking "just this once"

Key Patterns

Tests:

[RUN test command] [SEE: 34/34 pass] "All tests pass"

Build:

[RUN build] [SEE: exit 0] "Build passes"

Requirements:

Re-read plan → Create checklist → Verify each → Report gaps or completion

Quick Reference

Dimension Key point
Role Rigid iron law, the mandatory gate after implementation
Five steps IDENTIFY → RUN → READ → VERIFY → CLAIM
Forbidden "should" / "probably" / "seems" = not verified
After pass Show menu for user to choose the next flow (4 options)
Freshness Previous runs don't count — must be fresh evidence from this message

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.

gate is a skill published in the GitHub repository devnomad-byte/techneering (13 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 976 once invoked, about $0.0002 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.
