fusion-drift-doctor

fusion-drift-doctor is a skill for Claude Code from ahmedawan-oracle/claude-code-plugins. It costs 196 tokens per session (2,198 once invoked), scanned A, original, MIT.

A read-only diagnostic skill for schema drift between Oracle Fusion data and an AIDP pipeline. Schema drift means that a source column was renamed, removed, or changed type compared with the version the pipeline expects.

In plain words
What is it for?
Use it after specified AIDPF drift errors or when a seed or incremental run reports schema drift, to classify affected columns and choose the appropriate repair route.
Why use it?
It explains drift-gate failures and checks the live source so you can distinguish a changed source field from a problem in the pipeline's declared data structure.

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

fusion-drift-doctor 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.

The scan reads SKILL.md. This mod also ships 1 executable file (drift_classify.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

fusion-drift-doctor — what drifted, and how to fix it

The runtime gates DETECT drift and fail the run; they don't tell you which fix. This skill closes that: read the failure, probe the live Fusion PVO, classify each affected column, and route to the right remediation. Read-only — it diagnoses and hands off; it never edits packs/profiles or runs the pipeline.

When to use

  • A seed/incremental run failed with AIDPF-2072 / 4070 / 4071 / 2012 / 4040, or the summary says "schema drift" / "PVO drift".
  • "The Fusion PVO column got renamed", "bronze schema changed", "why does my incremental keep failing the gate?"
  • As a precheck inside /aidp-fusion-incremental before dispatch.

The gate codes it triages

Code What it means Route
AIDPF-2072 Live Fusion PVO schema drifted vs the bootstrap-pinned snapshot (a source column renamed/removed). classify → bootstrap --refresh or /medallion-author
AIDPF-4071 A declared outputSchema column is missing from the live PVO. classify (same as 2072)
AIDPF-4070 A live PVO column's type changed vs declared. /medallion-author — draft a bronze type-overlay (retype outputSchema to the live type) from the persisted AIDPF-4070__<node>.json
AIDPF-2012 Bronze table fingerprint drifted vs the pinned profile fingerprint. confirm the change is legit → bootstrap --refresh to re-pin
AIDPF-4040 Plan-hash drift — the node's plan-hash differs from the seed-pinned one. classify the cause (below) — re-seed only fixes a genuine plan-shape change

Note the distinction: PVO source drift (2072/4070/4071) is detected by a metadata-only BICC probe of the live PVO — it catches a renamed source column even when the bronze Delta table still holds the old one. Bronze-table drift (2012) is a DESCRIBE of the materialized table. Different layers.

Helper

File Role Invoked via

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.
