CrumbtrailDev/crumbtrail-cli

Plugin Claude Code

Failure archetype skills for Crumbtrail. Each skill pairs one recurring failure shape with the exact Crumbtrail MCP calls that confirm or rule it out, so an agent troubleshoots against a recorded session instead of a generic checklist.

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose an intermittent failure caused by ordering, where derived state is read after it was invalidated: a response that lands after the thing it was for went away, two writes that overwrite each other, a value that flips back. Use when the same steps sometimes work and sometimes do not. Names the Crumbtrail timing…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure whose real defect lives in a pinned upstream library rather than in application code, and whose fix is a version bump that may import the next breaking change. Use when a flow stopped working with no application change anyone can point at, when a symptom appeared everywhere at once, or when a bump…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure that appears only after content or configuration was promoted from one environment to another, where the promotion tool diffed by name and exact structure and a drifted schema, a duplicate name, an unsupported sub object or a rename broke the comparator, or the promotion reported success and…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure that differs between users or accounts on the same build because a feature flag or toggle is unset, stale, or doubling as configuration. Use when a feature works for one user and not another with identical code, when an old toggle blocks a new path, or when behaviour differs and nobody can say which…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a value that is serialized in one context and parsed in another, so a time zone, locale, calendar or numeric format flips it: off by hours, off by a day at midnight, a decimal separator swapped, money out by a factor. Use when a value is right in one place and wrong in another. Points at the recorded…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure where the reported status disagrees with the work, because status is written on a separate path from the work itself: success shown on failure, in progress forever, sync complete with zero rows, a 200 followed by a mid stream error. Use when an action was acknowledged and the effect is absent or…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a crash caused by an always present optional field that was absent for one row, model or mode, or by a null or oddly typed value reaching code that assumed presence. Use when a stack shows a property read on undefined or null and only some data triggers it. Explains how to read the captured payload that fed…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure that appears only on a rewritten or second implementation of a surface, where the new path silently omits behaviour the old path had. Use when a reporter says a feature works on the old screen, the old route, the old renderer or the previous release, and not on the new one. Explains which Crumbtrail…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure where a delete or a rename did not cascade to every row or pointer referencing the object, and the orphan detonates later in whatever dereferences it next. Use when something unrelated broke after a removal, when an object appears half gone, or when a screen fails on a reference to something that no…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure that works at small size and dies at a round number, where a fixed timeout, a parameter cap, a row maximum, an identifier length limit or an operation sized for the median account becomes fatal for a large one. Use when a flow works for most accounts and fails for the biggest, when something…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a change that does not take effect until a reload, a logout or a navigation away and back, because a cache or a piece of derived state has no invalidation hook on write. Use when a save appears to work but the screen keeps showing the old value. Names the Crumbtrail queries that prove the write landed, and…

CrumbtrailDev/crumbtrail-cli

Skill Claude CodeCodex

Diagnose a failure caused by something outside your control changing its payload, its authentication or its semantics, breaking a thin adapter that trusted the old shape. Use when an integration that worked for months starts failing with nothing shipped on your side, when a vendor call still returns success while the…
