Honest limits

A reliability tool that hides its own limits is not a reliability tool. Here are Molt's, stated plainly.

Credit figures are estimates

Bright Data publishes no per-operation price list. Every credit number anywhere in Molt — the CLI, the cockpit, an incident's cost-of-silence line — is a weighted estimate for relative usage, not a bill. See Credits for exactly how the weights are derived.

Healing is slow and capacity-limited

create and heal are AI-Flow jobs: five to twenty-five minutes each, behind a concurrent-job cap that returns 429 if two collide. Molt serialises them through a single slot rather than pretending otherwise — see Bright Data integration.

Targets must stay small

The intent analyser fails outright on large documents. A real 1.63 MB page killed two scraper create attempts at the very first pipeline step, and each failed attempt left an orphaned collector that cannot be deleted programmatically — someone has to remove it from the dashboard by hand. molt add measures a target's actual response size before ever calling create, and refuses above roughly 200 KB unless overridden with --force.

Bright Data cannot reach your laptop

Collectors run in Bright Data's cloud. A target on localhost is not a target — which is the whole reason this project's demo target, apps/chaos, is deployed publicly rather than run locally.

A small preview cannot prove a magnitude changed correctly

When a heal returns two preview rows against a sixty-row baseline, comparing raw counts would be comparing apples to a much smaller pile of apples. Heal & review covers what Molt says instead: that the sample is too small to compare sizes, while still standing behind what it can prove — a zeroed field is no longer zero.

Constraint

The false-green this project exists to catch, caught itself once. Early in the web cockpit's build, the Fleet page coloured a cell by raw fill rate. A field returning 0 instead of its real value still fills on every row, so it read 100% and rendered green — the exact failure Molt is built to detect, reproduced by its own dashboard. The fix was to classify every cell through the same compareSnapshots logic that drives incidents, never by fill rate alone; see Concepts for the distorted classification that makes this the correct reading today.

A verdict is only as good as the comparison it is made against

Every drift check compares two snapshots. If the baseline itself was captured from a broken run — pinned by mistake, or inherited from a bad first check — every later comparison inherits that mistake silently. Baselines covers the two commands that exist specifically to correct this by hand: nothing in the engine moves a baseline on its own.
