Adds system_logs with two variants:
- journalctl (systemd hosts): unit, since, lines, grep
- dmesg (any Linux): source, lines, grep
Both declare sudo: true — privilege escalation is handled by dispatch.
Also adds OR support in match conditions: array values mean any must
pass. Combined with AND across keys:
{"binary": ["journalctl", "systemd-cat"], "os": "linux"}
= (journalctl OR systemd-cat) AND linux
A .meta file can now declare multiple variants, each gated by match
conditions. The first variant where all conditions pass determines the
tool's schema, documentation, and executable. If no variant matches,
the tool is hidden from the registry on that host.
Match conditions:
binary — exec.LookPath or absolute path stat
file — os.Stat (file or dir exists)
os — runtime.GOOS
arch — runtime.GOARCH
env — environment variable is non-empty
nenv — environment variable is empty
This enables network-transparent tool declarations: one .meta file
works across heterogeneous hosts (systemd vs syslog, apt vs pacman,
GUI vs headless). When ollie-remote deploys to a different machine,
tools adapt their contract to what's actually available.
No variants field = current behavior, zero breaking changes.
Tools no longer need to be co-located in $OLLIE_TOOLS_PATH. The .meta
sidecar can specify a cmd field pointing to any executable:
- Absolute path: use directly
- Bare name: resolve via $PATH
Resolution order: OLLIE_TOOLS_PATH/<name> → meta.cmd → PATH lookup.
Local wrappers always win, enabling simplified interfaces over complex
system binaries.
Rewrites doc/WRITING_TOOLS.md to document the plugin model: any
executable + .meta = tool, no source tree integration required.
The Registry had its own discover() method that still required
'ollie:prompt' in file content — the old header-based check that was
removed from DiscoverTools(). This caused tool_load to fail for ALL
tools (not just Go binaries) since .meta is now the sole metadata source.
Fix: delegate to DiscoverTools() which correctly scans .meta files.
