Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00156 | $0.00692 |
| Opus 5 | $0.00078 | $0.00346 |
| Sonnet 5 | $0.00031 | $0.00138 |
| Haiku 4.5 | $0.00016 | $0.00069 |
Grade A, and why
docker-watch-mode-2025 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 13d 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.

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Docker Compose Watch Mode (2025 GA)
Docker Compose Watch enables automatic hot reload during local development by synchronizing file changes instantly without manual container restarts.
Three Watch Actions
1. sync - Hot Reload
For frameworks with hot reload (React, Next.js, Node.js, Flask). Copies changed files directly into running container.
2. rebuild - Compilation
For compiled languages (Go, Rust, Java) or dependency changes. Rebuilds image and recreates container when files change.
3. sync+restart - Config Changes
For configuration files requiring restart. Syncs files and restarts container.
Core Procedure
- Confirm the app already starts with
docker compose upbefore adding watch rules. - Prefer
syncfor source directories when the runtime already reloads files. - Use
rebuildfor dependency manifests, Dockerfiles, compiled artifacts, or base-image changes. - Use
sync+restartfor configuration files that are read only at process startup. - Add narrow
ignorerules for dependency folders, build outputs, VCS folders, caches, secrets, and generated files. - Run
docker compose up --watchand verify both fast source edits and dependency changes.
Usage
services:
frontend:
build: ./frontend
develop:
watch:
- action: sync
path: ./frontend/src
target: /app/src
ignore: [node_modules/, .git/, dist/]
- action: rebuild
path: ./frontend/package.json
Start with: docker compose up --watch.
Troubleshooting Checklist
- Change not detected: verify the watched path is relative to the Compose file and not excluded by
ignore. - Hot reload not firing: confirm the application inside the container has its own watcher enabled.
- Container restarts too often: split source
syncfrom manifestrebuildrules. - File ownership issues: prefer named volumes for dependency directories and sync only application code.
- Slow sync: narrow watched paths and exclude build outputs or large generated folders.
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.

docker-watch-mode-2025 is a skill published in the GitHub repository JosiahSiegel/claude-plugin-marketplace (54 stars, last pushed 2mo ago), licensed MIT. It adds 156 tokens to every session and 692 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
