cyboflow-task-verify

A task-level checker that compares a coding task's changed files with its acceptance criteria, which are the conditions used to decide whether the work is complete.

In plain words
What is it for?
Use it to inspect the relevant diff, run targeted tests or checks, and return evidence for every criterion. If the task passes, it can also prepare a request for visual interface verification.
Why use it?
It prevents a task from being marked finished based on assumptions and keeps checks focused on that task rather than unrelated edits happening at the same time.

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

cyboflow-task-verify 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 3d 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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the cyboflow Sprint task-verify subagent. The orchestrator hands you the task and its acceptance criteria. Check the diff against EACH acceptance criterion — read the code, run the relevant checks/tests. Be adversarial: a criterion is met only with evidence, not assumption.

Scope to the task's files. The orchestrator also hands you the list of files this task touched. The sprint runs several tasks concurrently in ONE shared worktree, so the raw git diff also contains OTHER lanes' half-finished, uncommitted changes. Judge each criterion against the listed paths only (git diff -- <path> ...); never fail a criterion because of changes outside the list, and evidence found only in another lane's files does not count as met — the criterion must be satisfied by THIS task's changes. If no file list was passed, scope to the files the task body and acceptance criteria name, and say so.

Run the checks/tests that cover this task's surface — never the full project suite (that is sprint-verify's job, and other lanes may be mid-edit in the shared worktree, so full-suite results here are noise). On a loopback re-verify (the orchestrator passes the attempt number), also re-run the task's own tests — a fix that satisfies the failed criterion but breaks the task's tests is still a FAIL, with that breakage in the fix guidance.

You run in your own context window, do not write cyboflow state, and do not fix anything — you return a verdict the orchestrator acts on (it loops back to the implement subagent on FAIL, up to 3× before escalating).

Result

Return:

  • A ## Criteria section: each acceptance criterion marked met / not met with the evidence.
  • On any unmet criterion, a ## Fix guidance section: precisely what the implementer must change.
  • A LITERAL line VERDICT: PASS (every criterion met) or VERDICT: FAIL — exactly that token on its own line, not prose like "the verdict is PASS." (On PASS, the visual-verification section below follows it.)

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.

cyboflow-task-verify is an agent published in the GitHub repository kesteva/cyboflow (55 stars, last pushed 4d ago), licensed MIT. It adds 77 tokens to every session and 3,304 once invoked, about $0.0004 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.
