Agentcrumbs
ericallam · Agent
Agentcrumbs gives AI coding agents a way to see what happened at runtime, not just read the code. As an agent implements a feature it drops structured traces, called crumbs, at its decision points. When something fails, the agent starts a collector, re-runs the code and queries the trail to see what executed, in what order and with what data. Crumbs are for development only and are stripped before merge, with a check that can fail CI if any remain.

Why it's useful
Agents can read code but cannot see what happened when it ran, so a recorded trail lets them fix the root cause instead of guessing.
What you could do with it
- Ask your agent to add trace points while it writes a feature, then query them when the feature misbehaves.
- Watch crumbs from several services interleaved in a live tail, each labelled by namespace.
- Run the strip command before merging, and its check mode in CI, to keep crumbs out of main.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.5.0, the file with digest sha512-+1J7w+x9/DP8oF+ZMVkeXilkd81ydygENEVwLJKwhA3uGQ947DFRwld9hGqAocOcuU4DaQKIdxTzKCsFhpV1Eg==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y -p agentcrumbs@0.5.0 agentcrumbsPinned to 0.5.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.
