How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
5 rules. About 0 are common, 3 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 8
Follow the code conventions in CONTRIBUTING.md.
- Very specific: line 12
Every capture source has a named flag, off by default, and an entry in docs/data-handling.md.
- Distinctive: line 14
Before consent, source discovery may return one ephemeral boolean for whether a configured root exists and is non-empty.
- Distinctive: line 28
Keep derived learning, revisions, backups, and private evaluation evidence in user-owned storage outside this public checkout.
- Distinctive: line 44
Keep removal bounded to recorded ownership.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Data handling
Follow the code conventions in CONTRIBUTING.md. Preserve the boundaries documented in docs/data-handling.md.
Consent and scope
Every capture source has a named flag, off by default, and an entry in docs/data-handling.md. Widening locations or content counts as a source change. Transcript access does not enable Git metadata, and reading skills does not authorize editing them.
Before consent, source discovery may return one ephemeral boolean for whether a configured root exists and is non-empty. Do not open entries or retain their names, paths, counts, timestamps, or provider identifiers.
Preserve repository and remote-owner boundaries. Unknown origins stay isolated. Global guidance requires explicit global evidence or a user decision. Managed policy limits cannot be widened by user configuration.
Learning input
Events carry pointers. resolveRedacted is the learning-text boundary: eligible excerpts pass through redactSecrets when materialized. Do not add competing downstream redaction gates. Derive fingerprints, metadata, and model-facing text from the same bounded source snapshot.
Exclude tool results, tool-returned file contents, thinking blocks, and data-access results from learning. Redaction reduces exposure without guaranteeing anonymity. Removing a redaction pattern needs a documented reason.
New sources need integration tests proving the adapter-to-redaction path, including excluded fields and synthetic secrets. Demonstrate that bypassing the gate makes the regression test fail.
Storage and publication
Keep derived learning, revisions, backups, and private evaluation evidence in user-owned storage outside this public checkout. Use independently authored synthetic fixtures. Do not copy private material into ignored repository files.
The index stores locators and metadata, without captured text. No raw transcript archive exists, and shadowclone does not upload or synchronize private learning state by default.
Preserve manual edits, ownership fingerprints, permissions, and supporting resources when publishing skills. Keep third-party packages and native memory read-only. Record reversible revisions and block overwrites when intervening edits conflict.
Model requests, diagnostics, and actions
Learning uses bounded redacted excerpts. Authorized coding runs can expose a repository to the selected provider, and evaluation judges receive unredacted generated code. Keep those distinct boundaries explicit; code evidence is not safe for logs or publication.
Log counts, sizes, hashes, source names, and opaque locators. Samples require an explicit debug flag and redaction. Never put raw capture or identifying transcript paths in errors or reports. Review any new network destination against the consent and purpose authorizing it.
Source, model, and publication permissions govern unattended learning. External actions require explicit approval for the particular action. The product does not commit, push, or act on GitHub itself; the shadowclone-work skill acts through the host agent's permissions.
Removal and verification
Keep removal bounded to recorded ownership. Preserve original transcripts and report edited artifacts that block cleanup. Document retention limits in the data-handling guide.
Exercise changed consent, scope, storage, redaction, and process boundaries with synthetic tests. Inspect new logging, file, process, and network sinks before handoff. Report material boundary changes and verification without copying sensitive evidence into the report.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
