gate-task-completion

gate-task-completion is a skill for Claude Code, Codex from ayeshakhalid192007-dev/graph-engineering-crash-course. It costs 50 tokens per session (883 once invoked), scanned A, original, MIT.

A completion check that verifies a task's own checker actually ran before an agent reports the task as done. It matches the exact task ID in the checker's run log.

In plain words
What is it for?
Use it in automated task loops to confirm that each proposed completion has matching checker-log evidence.
Why use it?
It prevents an agent from claiming success based on a similar task or an unverified result. Missing or mismatched checks are reported as a specific block.

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-task-completion 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

gate-task-completion

Reads a loop's proposed "done" signal for a task and the checker's run log, and decides whether the task's own checker entry actually exists — passing the loop through only when it does, and blocking with the specific missing check named when it doesn't.

Instructions

You are a Claude Code skill implementing the early-victory-guard pattern. Follow these steps in order:

  1. Read the loop's proposed "done" signal for the task, noting the task's own id exactly as the loop states it — this id is what you'll match the checker log against, not the ticket's subject matter or the plausibility of the resolution note.
  2. Read the checker's run log. Default to the tickets and log in this kit's README.md unless the user gives you a different set.
  3. Search the run log for an entry whose task id exactly matches the proposed "done" signal's task id. A near match — the right subject matter, the right loop, even the right day — does not count. Only an entry keyed to the exact task id counts as coverage.
  4. If no matching entry exists at all, block. State plainly that the checker never ran against this task, and name the task id that's missing coverage. Do not let a well-written resolution note substitute for the missing run.
  5. If a matching entry exists but is keyed to a different task id that merely looks similar (a typo, an adjacent ticket number, a logging mixup), treat this the same as no entry — block, and name the mismatch specifically: what task id the loop claimed versus what task id the log actually shows.
  6. If a matching entry exists for the exact task id, pass the loop through. The guard's job is only to confirm the checker ran against this task at least once — it does not re-run the checker itself and does not second-guess a pass or fail the checker already recorded.
  7. Report one outcome per task: PASS (with the matching log entry cited) or BLOCKED (with the specific missing or mismatched task id named). Never report a task without one of these two outcomes.

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-task-completion is a skill published in the GitHub repository ayeshakhalid192007-dev/graph-engineering-crash-course (5 stars, last pushed 9d ago), licensed MIT. It adds 50 tokens to every session and 883 once invoked, about $0.0003 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 2026-08-31.
