Summary

R007 (no-scripts-with-justfile) rejected any vx.toml [scripts] table in a
repository that also has a justfile. This changes it to judge each entry
instead of the whole table.

Surveying the six repositories that turn red under the baseline promotion
showed the blanket ban removes real entry points. The four build-ue* entries
in dcc-mcp-unreal depend on the [env] table and have no justfile
equivalent, so deleting them drops the only build entry point — which forced a
whole-repository skip_rules exemption on exactly the repositories where the
gate matters.

New behaviour

An entry is reported when either is true:

  • (a) forwarding — the value runs just <recipe> or vx just <recipe>.
    Leading whitespace and triple-quoted blocks are stripped first, so a
    multi-line script whose first command is just docs counts.
  • (b) name collision — the key names a recipe the justfile already defines.
    - and _ are treated as equivalent, so test_cov collides with test-cov.

Everything else is kept. vx run lint and just lint are two entry points for
the same intent and they drift — that is what the rule exists to stop. An entry
the justfile does not provide has nothing to drift from, so banning it costs a
real entry point to prevent a problem that cannot occur.

Implementation

  • scripts/check_repo_contract.py: check_no_scripts_with_justfile now filters
    per entry, with _script_forwards_to_just and _normalise_recipe_name as
    helpers. Findings carry the reason (forwards to \x`/shares the name of
    justfile recipe `x``).
  • contract/repo_contract.json: R007 title and summary rewritten to the
    per-entry semantics; the forwarding commands and interchangeable separators
    are new contract values (scripts_just_forward_commands,
    scripts_recipe_name_separators) so the gate and the vx-repo-contract skill
    cannot drift apart. contract_version bumped to 1.2.0.
  • docs/repo-contract.md: new "Per-entry judging (R007)" section; rule table
    row updated.
  • tests/test_repo_contract.py: the R007 case now covers all four combinations
    — forwarding, name collision (including -/_ folding), an unrelated entry
    beside a justfile, and no justfile at all.

Line reporting

parse_vx_toml now returns the 1-based line of every table.key it assigns,
and each finding points at vx.toml:<lineno> instead of naming the file.

This is not cosmetic. The rule exists for repositories with dozens of entries,
and a report that names vx.toml 42 times is unusable there — vx.toml:37
goes straight to the entry. Multi-line triple-quoted values point at the line
of the assignment, not at their continuation or closing delimiter.

Callers that only want the parsed mapping index element 0 as before; the
positions map travels in the context under vx_positions, so
adapter_contract_rules.py is unaffected apart from a comment.

Validation

  • python -m unittest discover -s tests -v — 312 tests, all passing.
  • Run against the six repositories, --profile strict --error-rule R007:
Repository entries reported kept exit
loonghao/vx 64 42 22 1
dcc-mcp/fpt-cli 23 19 4 1
dcc-mcp/dcc-mcp-photoshop 11 5 6 1
loonghao/GameLearningRuntime 11 11 0 1
dcc-mcp/dcc-mcp-unreal 4 0 4 0
loonghao/transx 4 1 3 1
  • Deleting the 42 reported entries from a copy of loonghao/vx gives exit 0
    with the remaining 22 kept and only pre-existing R009 warnings left.
  • A repository with [scripts] and no justfile reports nothing and exits 0.
  • This repository still passes its own gate: 0 errors, exit 0.
  • No skip_rules exemption is needed for any repository.
  • Every reported entry carries a line number: 42/42 in loonghao/vx,
    5/5 in dcc-mcp-photoshop, 11/11 in GameLearningRuntime, and so on;
    spot-checked against the source files.

Summary by CodeRabbit

  • Bug Fixes
    • Repository checks now report only script entries that forward to just or vx just, or conflict with a recipe name in justfile. Names differing only by hyphens and underscores are treated as matches.
    • Findings include the relevant script entry and, when available, its location in vx.toml.
  • Documentation
    • Updated the repository contract documentation to describe the revised checks and configurable matching rules.

📝 Walkthrough

Walkthrough

R007 now reports individual [scripts] entries that forward to just or vx just, or whose names match justfile recipes after separator normalization. The TOML parser records table and key line numbers, which the checker uses in findings.

Changes

R007 validation

Layer / File(s) Summary
Define R007 criteria
contract/repo_contract.json, docs/repo-contract.md
The contract and documentation define per-entry forwarding and recipe-name collision criteria. They specify configurable forwarding prefixes and name separators, and allow unrelated script entries.
Record TOML source positions
scripts/check_repo_contract.py, scripts/adapter_contract_rules.py, tests/test_repo_contract.py
parse_vx_toml now returns 1-based source positions for tables and keys. Callers and tests handle the added return value, and parser tests check locations for multiline values.
Evaluate per-script findings
scripts/check_repo_contract.py, tests/test_repo_contract.py
R007 detects forwarding commands and normalized recipe-name collisions, then uses recorded positions for finding paths. Tests cover per-entry behavior, unrelated scripts, severity, and multiline-entry locations.

R007 can miss prohibited scripts or flag permitted ones, and its fallback criteria can differ from the contract. Resolve these issues before merging unless the behavior is explicitly accepted.

Comment @coderabbitai help to get the list of available commands.

R007 previously rejected any vx.toml [scripts] table in a repository that
has a justfile. Sweeping the six repositories that turn red under the
PIP-3782 promotion showed the blanket ban hits real entry points: the four
build-ue* entries in dcc-mcp-unreal depend on the [env] table and have no
justfile equivalent, so removing them loses the only build entry point.
That forced a whole-repository skip_rules exemption on the repositories
where the gate matters most.

Judge each entry instead. An entry is reported when it forwards to the
justfile (`just <recipe>` / `vx just <recipe>`, tolerating leading
whitespace and triple-quoted blocks) or when its key names a recipe the
justfile already defines, with `-` and `_` treated as equivalent. An entry
the justfile does not provide has nothing to drift from, so it is kept.

The forwarding commands and the interchangeable separators are contract
values (scripts_just_forward_commands, scripts_recipe_name_separators)
rather than literals in the checker, so the gate and the vx-repo-contract
skill cannot drift apart.
parse_vx_toml now returns the 1-based line of every table.key it assigns,
and R007 points at `vx.toml:<lineno>` instead of naming the file once per
entry. In a repository with 42 offending entries a report that names
vx.toml 42 times is unusable, which is exactly the case the rule exists
for.

Callers that only want the parsed mapping index element 0 as before; the
positions map is carried in the context under `vx_positions`.

Accept tabs between a forwarding command and its recipe.

If a multiline script starts with just<TAB>ci, prefix + " " does not match the command. R007 then misses an entry that forwards to just. Match command whitespace rather than one literal space.

Keep R007 criteria in the contract.

These fallback lists define forwarding commands and recipe-name separators in Python. If a contract omits or misconfigures either value, the checker silently applies criteria that the contract does not declare. Validate the contract values instead of substituting rule criteria here.

As per coding guidelines: “Never hardcode a rule, threshold, or allowlist in a script. They belong in the JSON under contract/.”

Extract actual recipes before checking name collisions.

_justfile_recipes treats build := "value" as a recipe, but skips a quiet recipe declared as @lint:. With matching [scripts] names, R007 reports a false collision for build and misses the collision for lint. Restrict the extractor to recipe headers and include quiet recipe headers. Both forms are valid justfile syntax. (just.systems)
