Read the files your dispatch prompt names (plan, CONTEXT.md, PROJECT.md, project CLAUDE.md) before touching anything. Project CLAUDE.md directives are hard constraints; when they contradict the plan, CLAUDE.md wins - record the adjustment as a deviation.

Your prompt also names the risk surfaces this project answered. They are the bar the work is WRITTEN to: a task touching secrets, untrusted_input, concurrency or any other surface named there is built against it as you write it, not repaired once the risk_surface review fires on your committed range. They are not a halt condition and add no checkpoint - see <checkpoints>.

Batch independent probes throughout: greps, globs and reads whose target does not depend on another's result go out in ONE message, never one-then-wait. A probe you could only choose after seeing a prior result stays sequential.

To orient in a JS/TS file over ~20 KB, read it through node "${CLAUDE_PLUGIN_ROOT}/cadence-core/bin/skim.mjs" <file> - the same source with comments stripped and line numbers intact, roughly half the bytes. Then Read the exact range you will change: the comments are this codebase's design record and are what stop you re-breaking a fixed thing. Skim to find, Read to change.

Where skim.mjs does not apply - markdown, schemas, JSON - locate with grep -n carrying NO -A/-B/-C, then read the window those line numbers name. A grep returning nothing gets a LOOSER PATTERN, never a wider range; recovering a missed heading by dumping eighty blind lines pays for the miss twice. perl -ne 'print if /START/../END/' takes a section by its boundaries rather than by numbers you guessed. A -A40 on a FIRST probe is the tell that you are reading to find rather than reading to know.

For each task in the plan, in order:

1. Implement the task's change. Read ${CLAUDE_PLUGIN_ROOT}/cadence-core/references/lean-build.md (one consult site - this step) once per dispatch and hold its lean-first posture for every task: where a task's Verify: admits two shapes, you build the leaner one.

2. Verify falsifiably, prediction first: BEFORE running the task's Verify: command, state the exact output you expect to see. Then run it and compare. That command is what verifies the task; where a task names none, the test file the task's files map to, run by name. Never the full test suite per task or as a first probe: the suite has exactly one site, stated at the end of <process>. A surprise result - even a passing one - is evidence about the plan's assumptions: record it as [deviation] expected X, observed Y and only then act on it. Never rationalize an unexpected result after the fact into what you "really" expected. "It should work" is not verification.

3. Static analysis, before the commit. Run workflow.lint_command when it is set; when it is not, ask the project once per dispatch and run what comes back:

   node "${CLAUDE_PLUGIN_ROOT}/cadence-core/bin/planning.mjs" detect-commands --root <project root>
   

   Run its lint and its typecheck; either may be null, and both null means no static-analysis command Cadence can find - say so once and skip, an answer rather than a failure. Always spawn the subprocess: there is no in-host shortcut to skip it for. A failure here is a blocker and gets a carve-out of its own - see <deviation_rules>.

4. Commit per the commit protocol below.

5. Rewrite <plandir>/reports/plan-<k>.md (see <report_file>) with every row so far.
