Offload code search to deterministic tools instead of hand-grepping or reading whole files (P1). Climb the ladder lexical → structural → semantic, stopping at the first rung that answers. Use whenever locating symbols, call sites, definitions, or concepts in a repo.

Measure cost and context before justifying any harness change (P7). Read /context, /cost, /status and the tool-failure log to get before/after numbers; roll back anything that worsens a metric. Use when adding tools, evaluating a phase, or diagnosing quota burn.
GitNexus is a conditional accelerator, not a default navigation tool. Use it early only when the task already signals large-repo, cross-module, blast-radius, or unclear-flow uncertainty. Every candidate must be verified with rg/Probe before reading deeply or editing.
Compress output to the minimum that conveys the result (P8). Drop preamble, prose, and whole-file re-prints; deliver code, diffs, and file:line refs. Use on every response, scaling density to task size (lite / full / ultra).
Offload mechanical and type-aware edits to deterministic tools instead of LLM file-rewrites (P2). Use ast-grep --rewrite for repeated/mechanical transforms and Serena replace_symbol for single type-aware symbol edits. Apply whenever a change is rule-shaped rather than judgment-shaped.
Engineering guardrails for every change — the behavioral base of the policy spine. Make no unrequested assumptions, no over-engineering, no orthogonal edits, and match the surrounding code. Apply on every edit, plan, and review.
Portable code-review checklist. Use before a commit/PR or after a non-trivial change. Run it in a separate read-only helper when your runtime supports one; Sober ships the checklist, not a fixed reviewer.

Never hand-grep, never read a whole file to "look around." Each search is one offloaded call whose result is file:line + ~2 lines (P0/P8). Climb only as far as needed.
ripgrep (default). Exact strings, identifiers, regex.
rg -n "createSession" --type ts | head -50
rg -n "TODO|FIXME" -g '!*.test.*' | head -50
probe search "auth middleware" ./src
mgrep — concept queries only, last resort (cost + noise).
mgrep "where is rate limiting enforced" src/
| head — bounded output (P0).probe missing → rg).Need concrete recipes for a rung (regex flags, Probe queries, mgrep phrasing)? Read references/ladder.md.
