* docs(agents): restore and enforce progressive disclosure
* test(maestro): pin typed selector fallback signal
* docs(agents): address progressive disclosure review
* docs(agents): restore orphaned traps and close guidance-gate bypasses
- AGENTS.md: skills carry a minimal start/routing card; command semantics
stay in versioned CLI help (the skills contract enumerates two skills by
hand, so prose retains ownership for the rest)
- testing.md: restore the two local-only XCTest snags CI never hits
(unsigned-bundle policy refusal signature + first-run automation permission)
- scripts/gate/routing.ts: record GitHub's 300-changed-file path-filter limit
at the paths-ignore assertion it bounds
- agent-guidance-contract.test.ts: recurse docs/agents so nested guidance
cannot evade the byte budgets while the gate stays green
* docs: restructure AGENTS.md and CONTEXT.md for progressive disclosure
Apply the Claude 5 context-engineering guidance to the repo's agent docs:
keep the always-loaded file to gotchas and invariants, and move situational
guidance one hop away behind a routing table.
AGENTS.md 315 -> 229 lines. Cut generic agent-behavior boilerplate, three-way
duplication (Common Mistakes restated Hard Rules; Finding Source Owners
restated the registry section), and facts visible from the repo itself.
Kept verbatim: the expensive-lessons principles, enforcement gates, Hard
Rules, and environment traps.
Split out docs/agents/{cli-flags,pull-requests,device-verification}.md and
folded the Testing Matrix into docs/agents/testing.md, reframed around
pnpm check:affected so the prose stops duplicating the selector.
CONTEXT.md keeps all 50 terms, now grouped under a section index so a task
loads one section instead of the whole glossary.
* fix(check-affected): move the selector-owning sentinel to the Testing Matrix
The Testing Matrix moved from AGENTS.md to docs/agents/testing.md, but the
affected-check selector still treated only AGENTS.md as selector-owning. A
later matrix edit would have been classified as inert docs and skipped the
fail-open, so the selector could keep deriving gates from a spec that had
changed underneath it.
Move the sentinel with the prose, as a named SELECTOR_OWNING_DOCS set so the
next move is one line, and fix the two in-code comments plus the testing.md
paragraph that still pointed at the AGENTS.md matrix.
* docs: restore two rules dropped by the AGENTS.md split
Review caught two repo-specific rules that did not survive the move. Both are
prose without any backticked identifier, so the identifier-diff used to verify
the split could not see them.
- "Test through public interfaces; do not add unrelated production exports
solely to enable tests" returns next to the behavioral-tests rule in
docs/agents/testing.md, with the reason it exists.
- The guidance-ownership rule (decide whether new guidance/schema/metadata
belongs to the command surface, CLI grammar, CLI help, MCP projection, or
daemon runtime) returns to the always-loaded Docs & skills section, since it
governs all command-surface work and not just the flag case.
Also point the ADR routing row at docs/adr/README.md, which is already the
"read when you touch…" index, rather than at the bare directory.
