tilt

A tool for checking the health of Tilt development resources, investigating errors, reading logs, and working with Tiltfiles. Tilt is a tool that manages local development environments and their services.

In plain words
What is it for?
Use it to inspect Tilt resource status, separate errors from pending work, investigate logs, and diagnose deployment or development-environment problems.
Why use it?
It brings failed resources and their causes to the surface, including container health problems that ordinary status checks may miss.

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

tilt scanned grade A with 1 finding 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 2d 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.

Tilt

First Action: Check for Errors

Before investigating issues or verifying deployments, check resource health. Run errors first, separately from pending/in-progress — otherwise real failures get buried in 20+ pending lines:

# 1. Errors only — surface the buildHistory[0].error so you see WHY, not just THAT
tilt get uiresources -o json | jq -r '.items[] | select(.status.runtimeStatus == "error" or .status.updateStatus == "error") | "\(.metadata.name): runtime=\(.status.runtimeStatus) update=\(.status.updateStatus)\n  reason: \((.status.buildHistory[0].error // "(no buildHistory error; check tilt logs)") | gsub("\n"; " ") | .[0:240])"'

# 2. In-progress and pending — informational; an in-progress build may flip to error any moment
tilt get uiresources -o json | jq -r '.items[] | select(.status.updateStatus == "in_progress" or .status.updateStatus == "pending" or .status.runtimeStatus == "pending") | "\(.metadata.name): runtime=\(.status.runtimeStatus) update=\(.status.updateStatus)"'

# 3. Docker-compose container health — MISSED by the error filter above.
#    An `Up (unhealthy)` compose container keeps runtimeStatus=ok/update=ok, so
#    queries 1-2 never flag it; the red UI badge comes from healthStatus here.
tilt get uiresources -o json | jq -r '.items[] | select(.status.composeResourceInfo.healthStatus == "unhealthy") | "\(.metadata.name): compose healthStatus=unhealthy (HEALTHCHECK failing — service may still be up)"'

# 4. Quick status overview
tilt get uiresources -o json | jq '[.items[].status.updateStatus] | group_by(.) | map({status: .[0], count: length})'

If a resource is in_progress when you check, re-poll before declaring it healthy — it can transition straight to error with a populated buildHistory[0].error. The updateStatus field reflects only the current build attempt; the last error always lives in buildHistory[0].error even when updateStatus is none or not_applicable.

Docker-compose resources are a blind spot. Their runtimeStatus/updateStatus reflect only build/up state, NOT the container's docker HEALTHCHECK — so a probe-failing container (docker psUp (unhealthy)) reads runtimeStatus=ok and slips past queries 1-2, while the Tilt UI still reddens it. The authoritative signal is .status.composeResourceInfo.healthStatus (healthy / unhealthy / absent when the service has no healthcheck), which query 3 catches. These resources also have k8sResourceInfo: null (spec.type == "docker-compose"); to find why a probe fails, drop to docker: docker inspect <compose-project>-<svc> --format '{{json .State.Health}}' reads the probe's last exit code + output. A common cause is the healthcheck script invoking a CLI the image doesn't ship (e.g. curl/grpcurl removed in slimmed images) — the service is fine, the probe is broken.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

tilt is a skill published in the GitHub repository alleneubank/claude-code (52 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 1,291 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
