Let a Nix configuration declare gitea-axi's ambient context instead of
running a command that writes it. `setup` and `setup hooks` are write-only
against files the operator is assumed to own, so an operator whose agent
configuration is generated cannot use them at all.
The package installs the bundled Agent Skill to share/gitea-axi/skills and
publishes it as `passthru.skill`, alongside `passthru.sessionStartHook` read
from `session-start-hook.json` — a committed declaration the fast tier reads
too, so a test drives `setup hooks` and asserts the two agree.
On top of that, `homeModules.gitea-axi` declares both from those attributes
through home-manager's own Claude Code options, so an operator's existing
skills and SessionStart hooks compose rather than collide. Importing it
without enabling it yields a byte-identical generation.
The spec's Out of Scope entry deferring a home-manager module is deleted;
ADR 0020 records the reversal, and INSTALL.md describes both paths.
Grilling task 0042's mitigation found its framing too narrow. Recording an
absolute entrypoint path is one defect; the deeper one is that `setup` is
write-only, and an operator whose agent configuration is generated
declaratively cannot let it write at all. On such a machine both halves fail —
`setup hooks` against a read-only settings file, and `setup` on an unhandled
filesystem error — and the Agent Skill gets hand-copied into the operator's own
configuration, where it silently drifts from the package that ships it.
Three tasks follow:
- 0043 records the bare binary name, resolved through PATH, so the hook
survives an upgrade on any wrapper-based install. Fixes the marker-substring
coupling with it and drops the derivation's build-tree rename.
- 0044 reports an unwritable target as a structured error naming no cause,
rather than crashing.
- 0045 adds the declarative install path: a stable Skill location, the Skill
and hook specification exposed as Nix-consumable attributes, one committed
hook specification read by both the expression and the test suite, and a
home-manager module wiring them. Blocked by 0043, whose bare name the
specification declares.
CONTEXT.md gains the four terms this settled and amends `setup` and
`SessionStart hook`, which described the imperative path as the only one.
Entries for unbuilt work name the task that lands them, so the glossary does
not assert behaviour the code lacks.
The re-run-after-upgrade help text this branch added stays as it is: accurate
until 0043 removes it, which that task carries as a criterion.
