Mines this machine's agent transcripts for failed gameface, unity and cs2-dev MCP calls, and turns them into roadmap hits and entries.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Scanning transcripts for MCP failures

Every failed `gameface`, `unity` or `cs2-dev` call an agent made is evidence of a gap: grammar `eval` lacks, a message that sent the agent the wrong way, a mode a tool is missing. This skill counts the failures no earlier run counted, and lands them in `docs/ROADMAP.md` as **Hits** on the entry each one bears on, or as new entries.

[`scan.ts`](scan.ts) does the mining; its header states the ledger contract. Its state lives in `.scratch/mcp-failures/` and is machine-local, like the transcripts it reads.

## 1. Scan

Run `bun .agents/skills/scan-mcp-failures/scan.ts`. It prints the totals and one line per error signature, and writes every failure to `.scratch/mcp-failures/failures.jsonl` with its input, cleaned error and the agent's next four moves.

With no failures, go to "Record". A run with no ledger (a first run on this machine, or a wiped `.scratch/`) recounts failures the **Hits** already hold: count only those dated after an entry's `as of` date.

How to install

The exact contents, by fingerprint
mdr add citiesskylinesmodding/agents-plugins/scan-mcp-failures@sha256:1e414926825c3e29

The line at the top of this page pins the label git:20261102.ba5cd7f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
