odd-memory SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

odd-memory from using-system/oddyssey is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

The .odd/ memory - its contract and one reference per kind. The contract states what every kind shares (where the memory lives, the frontmatter and the whole body, append-only reports versus living-source benchmarks, recall by frontmatter then by section, the no-secrets rule, the work branch and the lone commit, the reply that carries a synthesis and never the artifact); each reference says how to persist, recall and show its kind - observation reports, instrumentation reports, benchmarks, the…

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

# The `.odd/` memory contract

The ODD loop's memory is a set of committed files in the observed
repository, under `.odd/`: git versions them, pull requests review them,
every user of the repository shares them — no side-channel storage,
nothing opaque. It has five kinds, each with the reference that owns
its specifics (its paths, its frontmatter fields, its recall matching,
its branch name, its commit subject, what its reply carries, and how a
stored one is shown):

| Kind | Store | Reference |
| --- | --- | --- |
| Observation reports | `.odd/observe-run-reports/` | [references/observe-run-report.md](references/observe-run-report.md) |
| Instrumentation reports | `.odd/otel-instrumentation-reports/` | [references/otel-instrumentation-report.md](references/otel-instrumentation-report.md) |
| Maintainer rulings | `.odd/decisions.md` (findings) and `.odd/entry-classifications.md` (tree entries), written by `scripts/odd_ledger.py` | [references/decisions.md](references/decisions.md) |
| Benchmarks | `.odd/benchmarks/<name>/` | [references/benchmark.md](references/benchmark.md) |

How to install

The exact contents, by fingerprint
mdr add using-system/oddyssey/odd-memory@sha256:35218d192c1b8e65

The line at the top of this page pins the label git:20260918.535f541, 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.
