# An installed skill's page

Why these rules: docs/rem-skills/rem-page-skill.md

Keep the core headings `What it does`, `Insight`, `When to use`, `Current status`,

`How to use`, `Inputs and outputs`, `Usage history`, `Limitations`, `Uncertainties`,

`Source` and `Sources`. Keep other headings only when evidence fills them; omit

an optional section whose whole body would be Unknown. Keep the order below:

```markdown

# <Name>

## What it does

## Insight

## When to use

## Current status

## Example result

## How to use

## Inputs and outputs

## Usage history

## Performance

## Limitations

## Related projects

## Open threads

## Uncertainties

## Sources

```

**The short opening**

- `Insight`: 1–3 cited findings changing task choice, setup or verification.

Compare instructions with recorded outputs; name the mismatch, capability or

failure condition, consequence and next check. Prefer a specific trap or

conflicting rule over listing prerequisites. Put the execution-evidence

caveat in `Current status`, not in each Insight. Counts do not prove success.

- `What it does`: one plain sentence: the task and useful outcome. Metadata is

advertised capability, not verified behaviour.

- `When to use`: a concrete suitable task and an important unsuitable case, when

known. Never present invented examples as observed successes.

- `Current status`: latest observed run date, version/model, whether the task

was completed, actual output, quality assessment, known blockers; a few lines

linking the detailed run. With no reviewed run evidence: `Unknown — not

verified` (not "never ran").

- `Example result`: one real artifact or short excerpt with its run reference.

Label illustrative examples and failed/partial outputs.

- `How to use`: shortest verified invocation, prerequisites, working directory,

ideally at most three steps. Never expose credentials.

- `Inputs and outputs`: required inputs, expected outputs and their locations.

**Run evidence and statistics**

`Usage history`: observed runs, recent first: date, task, run ID/link, skill

version or source hash, model/configuration, completion, output/artifact,

quality assessment, elapsed time, failure reason. Missing fields stay Unknown.

Exit status, task completion and quality are three separate things: a clean

exit without the artifact is not completion; an unreviewed output is not good.

Link older records when numerous.

`Performance` summarizes observed records, never advertising:

- Date range, sources, coverage gaps, number of distinct runs (deduplicated by

run identity). No records means unknown, not 0% or zero runs.

- Completed, partial, failed, cancelled, unknown counts. A completion rate

states numerator, denominator and exclusions; never hide failures or compare

a truncated retry with a completed task.

- Quality separately, with a named rubric or review basis and number reviewed.

No invented numeric score; unreviewed outputs do not pass.

- Elapsed time and input/output tokens with units and per-metric sample sizes;

per-run totals apart from per-call usage. Never infer tokens/second from task

duration; use generation timing. Never invent cost or token telemetry.

**Limits and maintenance**

- `Limitations`: scope, dependencies, known failure patterns and workarounds,

each evidenced.

- `Maintenance`: verified maintainer/contact, recent dated changes and whether

they were validated. Earlier successes do not verify a newer version.

- `Related projects`: observed associations and valid links only.

- Notebook links use notebook paths. Do not copy source-relative

`../name/SKILL.md` links into the catalog; use a verified catalog link or

the plain skill name.

- `Open threads`: concrete next actions, owners/dates when known.

- `Uncertainties`: missing logs, unread sources, stale results, unresolved

identity/version attribution. Do not manufacture a complete-looking dashboard.

- `Source`: the map owns it: the source file (linked, never pasted), discovery

location, allowed tools and every installed copy, identical or differing by

content hash. Leave it as the map wrote it.

- `Sources`: numbered references with source id, date, confidence; every

investigated claim cited. Mark inference.

**Mapping and later review**

Mapping owns installed copies and session counts. Review adds evidence and

preserves those markers, identity, useful prior content and `Investigation:`.

Never execute a skill merely to document it.

Catalog pages go in `skills/catalog/`. Review source and retained eval summaries;

never read mail or execute the skill for this review.
