Night Market Config Catalog Skill for Claude

Night Market Config Catalog

Every configuration axis in this repo: where it lives, what the

options and defaults are, whether it is production policy or an

experimental opt-in, and what guards it. Flags drift, so every

axis ends with a one-line re-verification command. Run it before

trusting a value stated here.

Terms used once, defined once:

• Axis: one independently tunable configuration surface (a

file, a key, or an environment variable).

• Guard: the mechanism that notices when the axis breaks or

drifts (a test, a pre-commit hook, a CI job, or a script).

• Shadow mode: a hook that evaluates and warns but does not

block. The blocking posture is opt-in.

Axis table

| Surface | File | Key options and defaults | Status | Guarded by |

|---------|------|--------------------------|--------|------------|

| Quality gate thresholds | .claude/quality_gates.json | enforce_blocking true, max_critical_issues 3, max_warnings_per_dimension 5; per-dimension keys below | Production policy | Documented in docs/quality-gates.md; consumed as policy prose by sanctum PR workflows (see caveat below) |

| Context governance | .claude/context_governance.json | enforce_strict_limits false, require_progressive_disclosure true, require_modular_structure true, require_optimization_level "standard", block_on_critical_violations false, max_violations_per_file 5 | Production, advisory | docs/quality-gates.md |

| Repo Claude settings | .claude/settings.json | Contains only a description key. NO hooks registered at repo level; all active hooks ship from plugins | Production invariant | Convention; see night-market-architecture-contract |

| Behavioral rules | .claude/rules/*.md (8 files) | bounded-discovery, markdown-formatting, plan-before-large-dispatch, prefer-invariants-over-fallbacks, prefer-rg-over-grep, shared-utility-consumer-rule, skill-exit-criteria, slop-scan-for-docs | Production | slop CI, pre-commit, review practice |

| Python toolchain | root pyproject.toml | See "Root pyproject tool tables" below | Production | Pre-commit hooks, typecheck.yml, security.yml |

| Per-plugin coverage | plugins/*/pyproject.toml [tool.nightmarket] | coverage_threshold = 90 in 19 plugins, 85 in gauntlet (20 files total) | Production | Read by scripts/run-plugin-tests.sh |

| Pre-commit pins | .pre-commit-config.yaml | Remote pins: pre-commit-hooks v6.0.0, bandit 1.8.6 (last release supporting the 3.9 system interpreter). Ruff runs from a local repo via the uv-managed binary so hook and make format share one version | Production | scripts/check_pinned_versions.py, python39-compat.yml |

| Plugin manifest trio | plugins/<p>/.claude-plugin/plugin.json, .claude-plugin/metadata.json, openpackage.yml | All three carry version in lockstep with the marketplace (1.9.15 at compile time) | Production | plugins/sanctum/scripts/update_versions.py, plugins/abstract/scripts/validate_plugin.py |

| Marketplace version | .claude-plugin/marketplace.json top-level version | Single ecosystem version, source of truth for the fan-out | Production | update_versions.py <version> bumper |

| MCP servers | .mcp.json | One stdio server: markitdown via uvx markitdown-mcp | Production | Manual |

| LSP config | .cclsp.json | pylsp for py/pyi; typescript-language-server for js/ts and markdown | Production | Manual |

| Feature-review scoring | .feature-review.yaml | version: 1; weight tables for value and cost; thresholds high_priority 2.8, medium_priority 1.8, confidence_warning 0.6 | Production | Consumed by imbue:feature-review |

| Egregore runtime config | .egregore/config.json (runtime file, created in the target repo, not committed here) | Nested dataclasses in plugins/egregore/scripts/config.py: overseer, alerts, pipeline, budget, discussions. pipeline.completion_integrity = False | Experimental opt-in flag inside production config | Unit tests in plugins/egregore/tests/test_config.py (default, roundtrip, and raw-JSON opt-in paths) |

| Herald Stop-hook judge | plugins/herald/hooks/hooks.json + env vars | Stop hook double_shot_latte.py registered with timeout: 10; internal LLM_TIMEOUT_SECONDS = 8 | Hook production, LLM path experimental | Guard test asserts LLM timeout stays under the registered hook budget |

Caveat on the two .claude/*.json policy files: no Python

script in the repo reads them directly. They are policy inputs

referenced by docs/quality-gates.md and by sanctum command

prose (prepare-pr, pr-review configuration). Treat them as

contract documents for review workflows, not as runtime config

a daemon loads. Direct programmatic consumers: none found at

compile time (candidate: wire one before tightening values).

Quality gate dimensions (.claude/quality_gates.json)

Per-dimension keys and defaults:

| Dimension | Keys | Blocks? |

|-----------|------|---------|

| performance | max_file_size_kb 20, max_tokens_per_file 5000, max_function_lines 60, max_complexity_score 12 | No (block_on_violation false) |

| security | block_hardcoded_secrets true, block_insecure_functions true, require_input_validation true | Yes (block_on_violation true) |

| maintainability | max_technical_debt_ratio 0.3, max_nesting_depth 5 | No |

| compliance | require_plugin_structure true, require_proper_metadata true | No |

Security is the only blocking dimension. Everything else is

advisory, capped globally by max_critical_issues: 3.

Root pyproject tool tables

Root pyproject.toml (version 1.9.15, requires-python >=3.12)

carries these tables:

• [tool.ruff]: line-length 88, target-version py312.
• [tool.ruff.lint] select: E, W, F, I, B, C4, UP, PLC0415,

PLR0913. extend-ignore: E501, B007, B008, B905, E402, and

UP017. UP017 is load-bearing: it keeps timezone.utc instead

of the 3.11+ datetime.UTC alias because hook scripts must

import under the system Python 3.9. Removing it re-breaks

hooks (this has happened three or more times, and an AST test

now holds the line).

• [tool.ruff.lint.per-file-ignores]: tests get S-series and

assert allowances; /__init__.py gets F401; /hooks/*.py

gets BLE001, PLC0415, E402 (resilience lazy imports);

scripts/*.py gets E402.

• [tool.pytest.ini_options]: norecursedirs includes

plugins/*, so plugin tests MUST run per-plugin. Markers:

unit, integration, e2e, slow, network, plugin, skill, hook,

command, bdd, benchmark. --strict-markers is on.

• [tool.coverage.report]: fail_under = 85 at root.
• [tool.mypy]: python_version = "3.12" with strict-leaning

flags (disallow_untyped_defs, warn_unused_ignores, etc.).

• [tool.uv.workspace] members: plugins/abstract,

plugins/leyline, plugins/conserve, plugins/core (a minimal set

for linting, not all 26 plugin dirs).

• [tool.bandit] skips: B101, B103, B105, B108, B110, B112,

B310, B311, B404, B603, B607, B608. Each skip has an inline

rationale comment in the file. Keep that pattern when adding

one.

Manifest trio and the two semver namespaces

Each plugin ships three manifests that must stay in sync:

• .claude-plugin/plugin.json: name, version, component arrays.
• .claude-plugin/metadata.json: version, dependencies,

provides, claude integration block.

• openpackage.yml: cross-framework manifest (name, version,

description, keywords).

Two distinct semver namespaces appear in metadata.json and are

easy to confuse:

• The ecosystem version ("version": "1.9.15"), bumped in

lockstep from marketplace.json by

plugins/sanctum/scripts/update_versions.py <version>.

• Capability dependency ranges, for example imbue declares

"dependencies": {"abstract": ">=2.0.0"}. That 2.0.0 is a

capability-contract version, NOT the marketplace version.

Do not "fix" it to 1.9.x during a bump.

Environment variables

| Variable | Consumer | Values and default | Effect | Status |

|----------|----------|--------------------|--------|--------|

| VOW_SHADOW_MODE | imbue hooks via plugins/imbue/hooks/shared/vow_utils.py | Default "1" (shadow). Set 0 to block | Vow hooks (bounded reads, scope ramp, package hallucination, no-AI-attribution, no-emoji-commits) warn instead of blocking | Shadow default is production; blocking posture experimental |

| UV_TOOL_DIR | root Makefile (line 9) | Default ./.uv-tools | Where uv installs tools; ruff resolves from $(UV_TOOL_DIR)/ruff/bin first on PATH | Production |

| SKRILLS_REPO | root Makefile (skrills-build) | Default $HOME/skrills | Source checkout used to cargo-build the skrills binary | Production (skrills itself optional; Python fallbacks exist) |

| CONSERVATION_MODE | plugins/conserve/hooks/session-start.sh | quick, deep, normal; default normal; unknown values warn and fall back to normal | How much conservation guidance loads at session start | Production |

| DOUBLE_SHOT_LATTE_LLM | plugins/herald/hooks/double_shot_latte.py | Set "1" to enable | Enables the LLM "second shot" tiebreaker, only on the single ambiguous Stop-hook outcome | Experimental opt-in, default off |

| DOUBLE_SHOT_LATTE_MODEL | same hook | Default "haiku" | Model used for the second shot | Experimental |

| DOUBLE_SHOT_LATTE_MAX_CONTINUATIONS | same hook | Integer (read from env; see hook source for cap semantics) | Caps forced continuations | Production guard |

| CLAUDE_HOOK_JUDGE_MODE | same hook | "true" disables the LLM path | Prevents the judge from invoking itself recursively | Production guard |

Experimental and opt-in flags

Both current experiments follow the same pattern: default off,

guard tests, blocking behavior only on explicit opt-in.

egregore completion_integrity

• Key: pipeline.completion_integrity, a bool defaulting to

False in the PipelineConfig dataclass at

plugins/egregore/scripts/config.py (line 49 at compile

time).

• Stored in the target repo's .egregore/config.json, read by

the summon skill alongside .egregore/manifest.json.

• When True: a quality verdict of "fix-required" becomes a

step failure (cannot advance to ship) and merge is held for

human review regardless of auto_merge.

• Guards: plugins/egregore/tests/test_config.py covers the

False default, the opt-in roundtrip, and loading from a

hand-written raw JSON file.

herald LLM second shot

• The Stop hook itself is production (registered in

plugins/herald/hooks/hooks.json with timeout: 10).

• The LLM tiebreaker is gated three ways: DOUBLE_SHOT_LATTE_LLM

must be "1", judge mode must not be active, and the turn

must land on the single ambiguous outcome (every confident

verdict skips the LLM entirely).

• LLM_TIMEOUT_SECONDS = 8 is deliberately under the 10-second

registered budget. A value above the budget once made the harness

kill the hook before any verdict (full record:

night-market-failure-archaeology SB7). A guard test now asserts

the ordering. Never raise the LLM timeout without checking the

registered budget first.

Adding a config axis

Checklist for any new flag, threshold, or env var:

• [ ] Default preserves current behavior (default off, or the

value the system already exhibits).

• [ ] A guard test asserts the default AND the opt-in path,

including loading from raw serialized config

(model: plugins/egregore/tests/test_config.py).

• [ ] Env vars validate their input and fall back to the default

on unknown values with a warning

(model: plugins/conserve/hooks/session-start.sh).

• [ ] Any timeout inside a hook is asserted against the hook's

registered budget in hooks.json.

• [ ] Add a row to the axis or env var table in this file, with

status (production or experimental) and guard.

• [ ] Add a one-line re-verification command under Provenance.
• [ ] If the axis affects gating or review policy, update

docs/quality-gates.md and route the change through

night-market-change-control.

When NOT to use

• Running tests, lint, gates, or releases: use

night-market-operations.

• Deciding whether a config change is allowed at all, or how to

review it: use night-market-change-control.

• Plugin/skill/hook mechanics (what hooks.json fields mean,

how manifests load): use claude-code-plugin-reference.

• Recreating the toolchain (uv, Python versions, skrills): use

night-market-build-and-env.

• Diagnosing a broken gate or hook: use

night-market-debugging-playbook.

Exit Criteria

• [ ] Every re-verification command under Provenance exits 0 and

its output matches the value stated in this catalog.

• [ ] jq -r '.version' .claude-plugin/marketplace.json equals

the version in each plugin's plugin.json, metadata.json,

and openpackage.yml (spot-check at least one plugin).

• [ ] rg -l "coverage_threshold" plugins/*/pyproject.toml | wc -l

returns 20. Any other count means this catalog is stale

and must be updated before use.

• [ ] rg -n "completion_integrity: bool = False" plugins/egregore/scripts/config.py

matches. If the default changed, the Experimental section

here is wrong and must be rewritten.

• [ ] A new config axis added by the current change appears in

the axis or env var table with a guard and a

re-verification one-liner.

Known drift risks: pre-commit rev: pins (guarded by

scripts/check_pinned_versions.py), the coverage-threshold file

count (20 at compile time), the egregore config.py line number,

and the promotion status of the two experimental flags (see

night-market-completion-integrity-campaign for the promotion

question).
