telepresence: Skill for Claude Code

.claude/skills/regression-tests/SKILL.md

regression-tests is a skill for Claude Code, Codex from telepresenceio/telepresence. It costs 82 tokens per session (1,608 once invoked), scanned A, original, Apache-2.0.

A runner and debugging guide for Telepresence’s regression tests, which are integration tests that check several parts of a system working together. The tests require a local Kubernetes cluster and reachable container images.

In plain words
What is it for?
Use it to run or debug an area, suite, or individual regression test, with Go’s test filtering and environment settings such as the local container registry.
Why use it?
It explains how to select only the relevant test or suite and how the test environment affects results. This avoids running the entire integration suite when a narrower check is enough.

Written for Claude Code and Codex: installed under .claude/, but also agents/openai.yaml present.

This is telepresenceio/telepresence's own configuration. It tells Claude Code and Codex how to work on telepresence itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything telepresence configures →

About the project

Telepresence is a development tool that connects a local computer to a remote Kubernetes or OpenShift cluster, allowing a locally running service to receive cluster traffic and use the remote environment. Developers use it to test and debug services with their usual tools without repeatedly rebuilding and deploying containers. The catalogue add-ons help operate Telepresence connections and workflows.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 51
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
  • medium Excessive Agency · line 132
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

regression-tests 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 10d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

regression-tests

Runs the telepresence regression suite from the main conversation, where this harness's shell-env quirks are known.

Background to assume

  • Tests live under regression_test/ and need a working k8s cluster (kind / minikube / Docker Desktop) plus images it can reach. For a local cluster set RTEST_REGISTRY=local and LOAD the images into it rather than pushing.
  • regression_test/README.md is the reference: fixture-engine rules, the RTEST_* table, catalogs, labels, coverage. Read it before debugging a fixture problem.
  • The shell environment always wins; there is no config file. That means a stale export in the user's shell silently changes a run.

Scoping: plain go test -run

Areas are ordinary Go tests, suites and methods are subtests, so one -run expression selects at any depth:

go test ./regression_test -run '^TestIntercept$'
go test ./regression_test -run '^TestIntercept$/^HeaderFilter$'
go test ./regression_test -run '^TestIntercept$/^HeaderFilter$/^Test_PathPrefix$'

There is no TEST_SUITE/TEST_NAME indirection and no make-argument dance: inline VAR=value prefixes work in this harness, so run go test directly and keep make check-regression for the full unscoped suite.

Always pass -count=1 (results must never come from the test cache) and a -timeout that fits the scope: minutes for one suite, -timeout=100m for a full run.

The run command

TELEPRESENCE_REGISTRY=local TELEPRESENCE_VERSION=<version> \
  RTEST_CONTEXT=<context> RTEST_TEARDOWN=1 \
  go test -count=1 -timeout=30m -run '^TestArea$/^Suite$' ./regression_test \
  > /tmp/rtest-suite.log 2>&1
  • RTEST_CONTEXT pins the kube context. Pin it explicitly whenever the machine has more than one cluster — the default is the kubeconfig's current context, which is one kubectx away from being the wrong cluster.
  • RTEST_TEARDOWN=1 destroys the run's resources at the end. Without it, dev mode keeps namespaces, the release, and the connection for the next run to adopt, which is what makes a scoped rerun take seconds.
  • RTEST_FRESH=1 ignores adoptable resources (use when a previous run left something suspect). CI implies fresh + teardown.
  • RTEST_LABELS / RTEST_SKIP_LABELS select on compat-core, slow, stress, flaky-retry.

Changes

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.
