@senior: issue #17 — live agent capability table via Gitea 1.27 /api/v1/token

skill-gitea-api.sh now introspects each agent's own PAT (AGENT_TOKEN +
TOKEN_PM/SENIOR/JUNIOR/LEAD/QA) via GET /api/v1/token — a Gitea 1.27+
self-introspection endpoint (token-in, scopes-out, no password) — and bakes a
live, always-accurate 'who can do what' matrix into SKILL.md. Every agent that
loads gitea-api sees every teammate's real scopes; no hand-maintained table to
drift when scopes rotate. Falls back to a static note on <1.27 or unset tokens.

agent.yml passes GITHUB_SERVER_URL + the per-agent TOKEN_* secrets into the
gitea-api skill step so the script can introspect them. run-agent.sh adds a
roster note pointing agents to the matrix for capability-based routing.

Least-privilege gating (plan point #3) was already done in issue #22 via
agents.json skills arrays + install-opencode.sh permission.skill scoping, so
no redundant case gates are added here.

 find the owner/repo for a `#N` in *this* repo, just use `${GITHUB_REPOSITORY}`.
 
+### Search for similar/related past issues by keyword (knowledge base)
+
+When a new issue looks like something the maintainer may have answered before, search
+for similar issues **before** asking clarifying questions — reuse prior answers instead
+of re-asking. Two variants:
+
+```bash
+API="${GITHUB_SERVER_URL}/api/v1"
+# Same-repo: list issues on THIS repo matching keywords (all states, issues+PRs).
+# ${GITHUB_REPOSITORY} is "owner/repo" for the current repo.
+curl -sS -H "Authorization: token $AGENT_TOKEN" \
+  "$API/repos/${GITHUB_REPOSITORY}/issues?q=deploy+traefik&type=issues&state=all&limit=20" \
+  | jq -r '.[] | "#\(.number) [\(.state)] \(.title)"'
+# Then read a matched issue's thread (see the "Open a referenced issue" example above).
+
+# Cross-repo: search issues across ALL repos the token can see on this instance.
+# Use the owner's name when you know it (e.g. the homelab repo), or leave it open.

+```
+
+Tips:
+- Pick keywords from the new issue's title/body (service names, error strings, the
+  action being requested). Try a couple of phrasings if the first returns nothing.
+- `state=all` matters — past answers are usually on *closed* issues, which `state=open`
+  would hide.
+- When you find a match, open its thread and read the maintainer's answers there; cite
+  the matched issue (e.g. `homelab#103`) in your plan and reuse those answers. Only ask
+  about things genuinely not covered by the precedent you found.
