dependency-bump

dependency-bump is a skill for Claude Code, Codex from CrumbtrailDev/crumbtrail-cli. It costs 79 tokens per session (1,523 once invoked), scanned A, original, MIT.

A troubleshooting guide for failures caused by a pinned third-party library, such as a client library, driver, runtime, or rendering engine, rather than by your application code.

In plain words
What is it for?
Use it to investigate flows that suddenly stopped working, failures affecting many users at once, or regressions introduced after deliberately updating a dependency.
Why use it?
It helps separate an upstream regression from a local bug and assess the breaking changes that may arrive with the version bump.

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

dependency-bump 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The dependency bump double edge

The defect is not in code anyone here wrote. It sits in a pinned upstream: a client library, a driver, a runtime, a rendering engine. The fix is a version bump, and the bump is the second edge, because it also brings the next breaking change with it.

Symptom

A flow that worked stops working, and nobody can name an application change that would explain it. The failure often arrives for many users at the same moment rather than spreading. The mirror image is just as common: a bump was made deliberately to fix one thing, and something unrelated that also sits on that library changed behaviour at the same time.

Do not write the cause down yet. A release regression in first party code produces exactly this symptom, and so does a vendor changing a payload out of band.

What Crumbtrail can see

A session carries the moment it was recorded, console errors and unhandled rejections including ones thrown from inside a bundled library, every request and response with status, timing and body subject to the capture size limit and the redaction policy, navigation, storage and cookie changes, backend spans where the backend integration is installed, and database row changes where the database adapter is installed.

The environment snapshot carries the browser name and version, the operating system, the viewport, the locale, the timezone, a public client release identity read from the <meta name="app-build"> tag when the page sets one, and whatever release, build, flag and config values the application declared to the SDK.

It does not carry a dependency manifest, a lockfile, an installed version list, or a diff of one. Nothing in a session records which version of a library was loaded, other than the browser's own version and whatever the application chose to declare. So a bump is dated by observing when recorded behaviour changed, and it is never read directly. When you write the finding up, say that the version was inferred from timing rather than observed, because the reader will otherwise assume you saw 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.

dependency-bump is a skill published in the GitHub repository CrumbtrailDev/crumbtrail-cli (0 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 1,523 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 2026-08-31.
