Holds `bin/tsk`, the graph tool, and `tools/SECRETS.md` (the secret-handling convention). It ships **no** predefined runbooks or CLI references — those accumulate in the user's KB. Read-only. - **Knowledge base** (`$KB`) — the user's private git repo, where all knowledge lives. Resolve it with `tsk kb` (use `$TSK_HOME/bin/tsk` if `tsk` is not on PATH). If no KB exists yet, offer to create one: `tsk init ~/troubleshoot-kb`. | Location | Holds | Your access | |----------|-------|-------------| | `$KB/incidents/` | archived investigations | **write** (only after the user confirms) | | `$KB/runbooks/` | the user's own SOPs | read-only (drafts need human review) | | `$KB/topology/` | services, deploy locations, dependencies, log sources | write (after confirmation) | | `$KB/tools/` | the user's own CLI / query references | read-only | | `$TSK_HOME/tools/SECRETS.md` | secret-handling convention | read-only | A fresh KB starts nearly empty (just templates) — knowledge builds up as you investigate. **Never edit this SKILL.md or any `runbooks/` on your own — SOP changes require an explicit user request or human review.** ## The seven steps ### 1. Search past incidents (always first) Search by keyword (service name, error code, component, symptom): ```bash tsk search "" # covers $KB/incidents and $KB/runbooks # or grep directly grep -ril "" "$(tsk kb)/incidents/" ``` If a similar case exists, read it first — last time's root cause and tool-call chain are usually reusable. ### 2. Match a runbook If `incidents/` has no hit, look for a matching SOP in `$KB/runbooks/` and follow it. A new KB has none yet — that's expected; proceed from first principles, and after resolving a recurring class, the feedback loop (step 7) will have you draft one. ### 3. Read topology When the investigation involves a specific service, read the topology first: - `$KB/topology/services.yaml` and `$KB/topology/dependencies.md` - If `*.local.yaml` / `*.local.md` siblings exist, they override — read them first. **Freshness:** check the "last updated" date in `$KB/topology/README.md`; if it is older than 30 days, warn the user that the topology may be stale and ask them to confirm. ### 4. Use the tool references Before calling any cloud CLI / kubectl / log query, check `$KB/tools/` for a matching reference and use its verified command templates. If none exists yet, proceed from general knowledge — and if you nailed down a reusable command form or a right-first-time query (correct profile/project/logstore), propose adding a short reference to `$KB/tools/` (copy `$KB/tools/TEMPLATE.md`). **Multi-account cloud: always pass the profile (don't run bare first, then switch).** With multiple cloud accounts the default profile/context is rarely the one you want; a bare query against another account's resources fails or — worse — silently reads the wrong environment. Resolve the service's `profile` (and `region`) from `$KB/topology/services.yaml` (`log_sources` / `clusters`) and put it on the first command. If topology has no profile for the service, list available profiles, then **write the correct mapping back** (see step 7). **Secrets:** use the CLI's own credential store (kube-context / named profiles); service secrets (DB passwords, API keys) come from env vars or a secret manager (see `$TSK_HOME/tools/SECRETS.md`). **Never write any secret into an archive** — record only "used credential X". **Boundary:** read-only ops (get / describe / logs / query) run directly; any write op (delete / restart / scale / apply / config change) must be shown to the user with its impact and confirmed first. ### 5. Investigate - **Focus on the target service; expand by evidence, not by topology.** `topology/` dependencies are a map of *where to look when needed*, not a checklist to pull every upstream/gateway log up front. Only expand to a dependency when the target service's own evidence points there (e.g. it returns 5xx and its logs show a failing downstream call, or you need the gateway access log to get the caller identity). State why before expanding. - List 1–3 hypotheses and verify each with evidence; don't conclude on a hunch. - Every conclusion needs command output or a log line as proof. - Record each key command you run (you'll need them when archiving). ### 6. Archive (only after explicit confirmation) Do **not** archive by default. Archive only when the user clearly signals both: 1. the issue is resolved / located / closed, or the current findings are worth saving as the conclusion, and 2. they want it saved / archived / recorded to incidents (or equivalent explicit wording). If they only said "check this" or "look at the logs", do not create an incident file or touch `incidents/INDEX.md`, even if you reached a conclusion. You may add: "Say the word and I'll archive this as an incident." After confirmation: ```bash tsk new "" # generates $KB/incidents/YYYY-MM-DD-.md with OKF frontmatter ``` Fill the template (`$KB/incidents/TEMPLATE.md`): - **Frontmatter** (`type/title/service/status/tags/timestamp`) — used by `tsk tag`, `tsk lint`, and the graph. - **Symptom** in the user's words + a normalized description (service name, error code, namespace — so it's grep-able next time). - **Timeline**: key moments only, not a transcript. - **Tool calls**: complete, copy-pasteable commands (with profile/context). This is the highest-reuse part. - **Root cause**: if not found, write "not located; currently suspect X, ruled out Y/Z". - **Redaction**: replace any AccessKey / token / password with `` or a placeholder — even though the KB is private. Then add one row to `$KB/incidents/INDEX.md` (date | service | symptom | root cause | tags | file). ### 7. Feedback loop **Topology / log-source correction — independent of archiving, fire any time (high value, don't skip).** Whenever the investigation corrected a topology fact, propose updating `$KB/topology/services.yaml` right then and write it after confirmation. Typical triggers: - You picked the wrong log project / group / logstore and only found the right one by trial — add the "service ↔ correct project/store/account/profile" mapping to `log_sources` so next time is a direct hit. - A service's namespace / cluster / replicas / domain disagrees with `topology/` → fix it. - New service, new dependency, or a decommissioned one → add/remove. This does **not** depend on whether you archive. Even for a "just check this" request that you don't archive, if you nailed down a correct log-source mapping, propose writing it back. After updating, bump the "last updated" date in `$KB/topology/README.md`. **Sediment a runbook (after archiving):** if the same class of issue has appeared ≥3 times in `incidents/`, propose drafting a new runbook into `$KB/runbooks/` (draft for the user; merges only after human review). ## Archive quality bar - Creating an incident / touching `INDEX.md` without explicit user confirmation is a defect — undo it. - Missing any of "symptom / tool calls / root cause (or progress)" → reject and rewrite. - No "see the conversation above" — an archive must be self-contained.
