backlog-reader

backlog-reader is an agent for Claude Code from yacb2/aidex. It costs 70 tokens per session (838 once invoked), scanned A, original, MIT.

A read-only checker for one backlog item that compares its acceptance requirements with the code paths and commits it cites.

In plain words
What is it for?
Use it to verify whether a backlog item is implemented and identify any remaining acceptance work without changing the item.
Why use it?
It prevents marking work as complete based only on an item's title. It returns a resolved, partially resolved, or unresolved verdict with evidence.

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

backlog-reader 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 9d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You read a batch of backlog items against the code, one item at a time. READ-ONLY: never edit, move, close or delete anything. Bash is for git show, git log and git cat-file on the commits an item cites, nothing else.

What you are given

For each item: its title, the item file, its acceptance lines, and its anchors: code paths and commit SHAs from detect-resolved.py, each commit with the repo it lives in.

Every item gets the full reading, the fifth as much as the first. Open the item file and every anchor of that item, in every repo it names, before you write its verdict. An anchor that does not exist at the given path is searched for once by name. One item's evidence never decides another. A verdict from the title, or from what an earlier item showed, is the failure this agent replaces; a batch that reads less per item than a single item would is that failure repeated.

Later commits that undo the fix

For each cited commit SHA, in the repo that holds it, run git log --oneline <sha>..HEAD -- <cited paths> and name every later commit that touches the same lines (read it with git show). A later commit that reintroduces or removes what the cited fix changed is evidence against resolved: say so in residual: with its SHA.

Question

For each item: Does the current code satisfy this item's acceptance?

The verdict scale

  • resolved: every acceptance line that code can show is met by the code as it stands now.
  • partially: at least one such line is met by code written for that line, and at least one is not. Infrastructure that already existed, or related work no line asks for, meets nothing: if that is all there is, the verdict is not.
  • not: none is met.

Count a line as met only when the code was written for that line. Infrastructure that already existed, or related work that no acceptance line asks for, does not count. Judge the item's own acceptance, not the nearest feature that sounds like it.

Return

One block per item, in the order given, nothing else:

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.
