Debug and investigate foci platform internals. API logs, payload logs, session files, CC backend transcripts, cache diagnosis, service logs, and common investigation patterns. Read the relevant subfile before investigating.

Security scanner for untrusted code and AI agent skills. Detects credential theft, code injection, privacy violations, deception, resource abuse, and ethical issues before you read or activate untrusted content.
How to operate as a foci agent — the tools you call, how your prompts and turns are built, the databases behind your state, and the config that shapes you. Read the relevant subfile before doing related work.
Finding text on disk — use ack, not grep (grep is only for filtering the piped output of other commands). Conventions for fast, correct file-content search across a codebase.
Drive a live browser via accessibility-tree snapshots — navigate, click, fill forms, select, press keys, screenshot. Use when a task needs interacting with a real web page (logins, JS-rendered content, multi-step flows), not a static read (that's web_fetch).
Developing the foci platform itself (Go server + backends). Architecture, the CC/opencode backends, the routing/delivery model, and the turn/steer/ask lifecycle — the internals you need when CODING foci, not when operating as an agent. Read the relevant subfile before changing that area.

How to investigate a running foci: where the data lives and how to read it. This SKILL.md is a directory; each topic lives in its own file.
This
SKILL.mdis yours to customise (seed-if-missing — override it, add your own sibling files). The content files it lists below ship with foci and are overwritten on restart — edit those in the foci repo (shared/skills/foci-debugging/), not the deployed~/shared/skills/copy.
| Subfile | Read it when you need… |
|---|---|
| logs.md | Service logs (~/logs/foci.log, the journal), the data-source scope map, per-agent SQLite DBs, and the log-reading gotchas (.gz archives, awk-not-grep, panics). |
| api-cost.md | Provider auth, the API call log (api.db), payload logs, and "where did the cost go?" — cost/token/cache-stat queries. |
| cache.md | Anthropic prompt-cache mechanics and cache-bust diagnosis (companion to the cache-diagnosis skill). |
| sessions.md | Session history files (stable-key JSONL), CC backend transcripts, the state.db session/archive/resume tables, and compaction/reset/cron lifecycle. |
For normal operation (not investigation) — tools, prompts, turn lifecycle, config — see the companion foci-usage skill.
