"""planning-with-files: one-process twin of inject-plan.sh and of the Claude
|
|
Code hook dispatcher in hooks/claude-hook.sh.
|
|
|
|
Why this file exists (v3.17.0). hooks/claude-hook.sh answered every lifecycle
|
|
event by running resolve-plan-dir.sh and inject-plan.sh, and those scripts
|
|
answer by forking: realpath, stat, sha256sum, awk, tr, mktemp, head, tail,
|
|
sed, wc, four separate Python starts, and a $(...) around most of them. One
|
|
UserPromptSubmit fire forks about 130 times, one PreToolUse fire about 60.
|
|
On Linux and macOS a fork costs one to three milliseconds and nobody noticed.
|
|
Under Git Bash on Windows a fork costs about 90 ms, so the same fire took
|
|
seven to twelve seconds against the 10 s hook timeout: Claude Code printed
|
|
"UserPromptSubmit hook timed out after 10s - output discarded", the plan
|
|
never reached the model, and every Bash, Read, Grep and Edit call waited five
|
|
more seconds before it ran.
|
|
|
|
This module does the same work in one interpreter start (about 60 ms). It is
|
|
a twin, not a replacement: scripts/inject-plan.sh stays the reference
|
|
implementation and the route every host without CPython 3 keeps using, and
|
|
tests/test_inject_plan_python_parity.py runs both over the same fixtures and
|
|
asserts byte-identical stdout.
|
|
|
|
Usage:
|
|
inject-plan.py --context=userprompt|pretool|precompact|preflight|validate
|
|
Same stdout as `sh inject-plan.sh --context=<ctx>` for the same project
|
|
state and environment.
|
|
inject-plan.py --claude-event=<event>
|
|
Same stdout as `sh hooks/claude-hook.sh <event>` for session-start,
|
|
user-prompt-submit, pre-tool-use, post-tool-use and pre-compact. The
|
|
stop event stays in the shell dispatcher: it must forward Claude's Stop
|
|
payload from stdin to gate-stop.sh untouched.
|
|
|
|
Exit status: 0 means "ran", and stdout is then the complete answer (possibly
|
|
empty). Any other status means "could not run"; the shell launcher falls back
|
|
to the reference chain. Nothing is written to stdout before the answer is
|
|
complete, so a failure can never leak half an answer. That write-once rule is
|
|
the contract the launchers rely on: capturing stdout in the shell would cost
|
|
another fork per event, the very thing this file exists to remove, so main()
|
|
is the only place that writes and it writes only after everything succeeded.
|
|
|
|
Meant to run under `python -I`: the project directory is then never on
|
|
sys.path, so a repository carrying its own secrets.py or hashlib.py cannot be
|
|
imported by a hook. Python 3.6 or newer, standard library only. No f-strings
|
|
and no annotations on purpose: an older interpreter must fail at import time
|
|
with a clean non-zero status, never half-way through the work.
|
|
|
|
Platform behaviors of the reference that ARE mirrored, because Claude Code on
|
|
Windows runs the shell chain through Git Bash and nothing else:
|
|
* Git for Windows' sed drops the carriage return before every newline it
|
|
processes, so the progress tail of a CRLF progress.md loses them.
|
|
* Git for Windows' gawk reads its input the same way, so smart extraction
|
|
of a plan line ending in "\\r\\r\\n" loses both carriage returns.
|
|
* Command substitution discards NUL bytes, so a NUL in .active_plan or in
|
|
an attestation file is dropped rather than making the value invalid.
|
|
* awk prints an uninitialized counter as the empty string, so a smart view
|
|
of a plan with no completed phase reads "phases: /3 complete".
|
|
* Cache keys are spelled with the launching shell's $PWD (handed over as
|
|
PWF_SHELL_PWD, excluded from MSYS path conversion), so both routes share
|
|
one turn-marker slot and one progress-guard slot per plan.
|
|
|
|
Known, accepted differences from the shell reference:
|
|
* Shell glob order follows locale collation; this twin uses code-point
|
|
order. This can change which three of four or more nested projects the
|
|
ambiguity notice names.
|
|
* BSD sed (macOS) appends a newline to a progress.md whose last line has
|
|
none; GNU sed and this twin do not.
|
|
* With PWF_PLAN_ROOT set under Git Bash the shell sees the pin as typed
|
|
and this twin sees it MSYS-converted, so notices quoting the pin and the
|
|
progress-guard key of a pinned plan can differ in spelling on Windows.
