Closes the procedural hole that kept making Codex sessions fall back
to ``examples/`` for YAML scaffolding even after the SKILL forbade it.
The lookup tool returns a canonical Oracle ``.drawio`` as the geometry
source, but the agent had no YAML version of that geometry to copy —
the .drawio is XML with stencil-encoded icons. Without a scaffold,
agents reverse-engineered or fell back to ``examples/`` (which is
forbidden but happened anyway because the alternative was painful).
New tool ``tools/archcenter_drawio_to_template.py`` extracts:
• canvas dimensions
• containers (region / vcn / ad / subnet) classified by stroke /
fill style markers
• service bounding boxes with ``type: TODO_identify`` (the icon
type is encoded in stencil bytes — agent fills it from the
renderer's TYPE_TO_ICON aliases when authoring the spec)
• edge waypoints (source, target, points)
Output lands at ``kb/diagram/assets/archcenter-refs/<slug>/_template.yaml``
next to the .drawio. Lookup now surfaces it as
``cached: yaml=<path>`` so the agent has a one-step "copy this YAML
and adapt" path.
Ran across all 132 cached folders: 107 templates emitted, 24 had no
.drawio (zip didn't ship one), 1 already cached.
Other persistent guardrails added in this commit:
- SKILL.md option 2 step 3: explicit reminder that valid ``type:``
values come from ``TYPE_TO_ICON`` / ``ICON_TYPE_ALIASES`` in the
renderer source plus the icon-index JSON files. Do NOT grep
``examples/`` for ``type:`` — that's where the previous Codex
session was looking, against the rule.
- ``make archcenter-templates-refresh`` Makefile target.
- The lookup index now also indexes ``_template.yaml`` per slug.
- Auto-extracted templates committed under
``kb/diagram/assets/archcenter-refs/*/_template.yaml`` so a fresh
clone has them on first lookup (no extraction step needed).

Three-layer defense to keep root SKILL.md (Claude Code) and
.agents/skills/oci-deal-accelerator/SKILL.md (Codex) byte-aligned.
Without this, Claude Code and Codex can drift and give the user
contradictory instructions — exactly the failure mode that produced
the workload-driven-mode incident on 2026-04-25.
Layers (least → most enforcement):
1. Local pre-commit hook (.githooks/pre-commit, opt-in via
``make install-hooks`` which sets core.hooksPath). When SKILL.md
is staged, auto-runs scripts/sync-skill.py and stages the
regenerated .agents/ copy in the same commit. Idempotent.
2. ``make install-hooks`` target + a tip line in ``make venv``'s
output so any new clone discovers the hook setup.
3. CI gate (.gitea/workflows/skill-sync.yaml) on every push/PR
touching SKILL.md or the .agents/ copy. Runs
``scripts/sync-skill.py --check`` and fails the build on drift.
Catches anyone who skipped the hook.
README documents the rationale and the three layers.

Implements points 3–8 of the post-procedure follow-up.
- Make targets: diagram-lookup, diagram-validate-spec, diagram-spec-audit,
archcenter-descriptions-refresh, archcenter-smoke. Promotes the new
tools out of "remember the CLI" into discoverable build-automation.
- .gitea/workflows/diagram-validators.yaml — runs spec validator across
every absolute_layout spec on push/PR, plus a drawio re-render smoke
test on the canonical example. Hard fail blocks merges.
- archcenter_pattern_lookup --llm-rewrite — opt-in (ANTHROPIC_API_KEY
env var, mirroring DRAWIO_EXE pattern). Rewrites natural-language
queries into canonical OCI terminology before scoring; falls back to
the original query on any error.
- diagram_spec_validator — documents the policy on legacy archcenter
reproductions: LABEL_NEAR_PARENT_EDGE stays a warning so verbatim
reconstructions don't lose pixel-fidelity from cosmetic edits.
- README — documents the asset refresh procedure (downloader +
description fetcher are idempotent, refresh quarterly).

The diagram path now follows a documented standard procedure (lookup
the closest Oracle Architecture Center reference → confirm components
→ author absolute_layout → spec validator → render → visually verify)
and ships persistent guardrails so layout regressions can't recur.
Persistent procedure changes (apply to all users, all sessions):
- tools/diagram_spec_validator.py — geometry checks (CONTAINER_TOO_THIN,
CONTAINER_PADDING_VIOLATION, LABEL_OVERFLOW_PARENT) run BEFORE either
renderer (drawio + PPTX). Catches the subnet-collapse / label-overflow
bugs that the post-render drawio validator missed.
- tools/oci_diagram_gen.py + tools/oci_pptx_diagram_gen.py — call the
spec validator before emitting any output. Adds mysql / mysql_heatwave
type aliases.
- tools/archcenter_pattern_lookup.py — scores against cached page
descriptions (not just the 1-line summary), supports --queries for
multi-fragment composition, and applies synonym expansion via
kb/architecture-center/synonyms.yaml so "LB HA cross AD" matches
"load balancer high availability availability domain".
- kb/architecture-center/synonyms.yaml — canonical synonym table
(load balancer, autonomous database, data guard, …) used by the
lookup scorer.
KB enrichment:
- tools/archcenter_description_fetcher.py + 121 cached _description.md
under kb/diagram/assets/archcenter-refs/<slug>/. Removes the runtime
dependency on docs.oracle.com when authoring specs and feeds the
pattern-lookup scorer.
- 110+ cached .drawio / .svg / .png references for offline reuse,
plus the OCI Toolkit v24.2 import (kb/diagram/assets/oci-toolkit-drawio).
Documentation:
- docs/skill/output-formats.md — new "Standard diagram-generation
procedure (MANDATORY)" + geometry rules + the new validator entry.
- SKILL.md option 2 — references the mandatory procedure.
- README.md — describes the spec validator, archcenter_pattern_lookup
and description fetcher, and updates the KB-health table.
Tooling that backs the procedure (cumulative across recent sessions):
tools/archcenter_case_runner.py, archcenter_batch_driver.py,
archcenter_zip_downloader.py, drawio_visual_validator.py,
drawio_fidelity_eval.py, harvest_drawio_icon.py, import_oci_library.py,
oci_pptx_diagram_gen.py, oci_pptx_render.py, refresh_pptx_icon_index.py.

- refresh_sku_catalog.py: add --discover to report API SKUs missing from
catalog, filtered to already-curated serviceCategory values. Auto-runs
at end of --validate and --refresh so gaps surface on every maintenance
pass. First run found 162 missing SKUs (Blackwell GPUs, X12 Ax compute,
VMware reserved tiers, WebLogic-on-OKE, Analytics/OIC BYOL).
- oci_bom_gen.py: fix Cost % column being blank. Back-fill was gated on
formula detection but data rows write raw numbers, so the predicate
never matched. Now tracks data_item_rows explicitly.
- .gitea/workflows/sku-catalog-refresh.yaml: monthly automation (1st at
09:00 UTC). Auto-refresh prices → push branch + open PR; detect new
SKUs → open issue with labels. Gated on secrets.GITEA_TOKEN.
- kb/pricing/oci-sku-catalog.yaml: add B95714 / B95715 (Autonomous ATP
Dedicated ECPU, LI + BYOL) — canonical SKUs for ADB-D pricing.
- kb/services/compute.yaml: add X12 family (VM.Standard4.Ax.Flex,
BM.Standard4.Ax.120), E6.Ax and A4.Ax variants. Verified against
docs.oracle.com computeshapes.htm. Bump last_verified + changelog.
- templates/bom-spec.yaml: document 730 hrs/month convention as default
(= real annual billing / 12; 744 overstates by 1.92% on 12-month TCO).
- Makefile: new 'make sku-discover' target.

Codex users hit `python: command not found` on the welcome-flow
pre-flight because SKILL.md called `python tools/kb_freshness.py`
directly. Any hardcoded version (python/python3/python3.12) breaks
for somebody — users have 3.8, 3.10, 3.11, 3.12 in the wild.
Fix: channel all skill-initiated Python calls through `make` targets
so the Makefile's single $(PYTHON) variable (auto-detected venv >
3.12 > 3.11 > 3.10 > python3) is the only place Python resolution
lives.
- Makefile: add `kb-check` target emitting JSON for the skill pre-flight
- SKILL.md + .agents/skills/.../SKILL.md: call `make kb-check` and
`make freshness-refresh` instead of bare `python tools/...`
- CLAUDE.md: same fix in the Welcome Flow instructions

Makes the skill work on any laptop regardless of installed Python version
or LLM harness, without per-command approval prompts or missing deps.
- Makefile: auto-detect Python (venv > 3.12 > 3.11 > 3.10 > python3)
and new `make venv` target that picks the best Python at creation time
- .claude/settings.json: project-level Claude Code permissions
(Write to examples/ and output/, common bash commands pre-authorized)
- .codex/config.toml: Codex sandbox config with network_access=true,
approval_policy=never, sandbox_mode=workspace-write — fixes
`make venv` failing with "No matching distribution" in Codex
- CLAUDE.md / AGENTS.md: document the `make venv` flow, drop all
hardcoded python3.12 references in favor of make targets
- CLAUDE.md: add Karpathy-style coding guidelines (think before coding,
simplicity first, surgical changes, goal-driven execution)
- .gitignore: add .venv/

Why this set of changes:
- KB pricing was drifting silently — domain files (database.yaml,
storage.yaml, etc.) had prices 30-800% off the live Oracle API and
nobody read them. The skill was auditing as stale on every check
with no path to fix it.
- The skill itself violated Anthropic's spec (`name` field had
uppercase/spaces) and was over the 500-line guideline (647 lines),
hurting discovery and load performance.
- Welcome flow occasionally improvised the menu instead of reading
SKILL.md, missing options.
Pricing — single source of truth, fully automated:
- Extend tools/refresh_sku_catalog.py with --refresh-domain compute,
pulls shape-level prices from the Oracle public pricing API
(apexapps.oracle.com), preserves manual fields (notes, GPU specs,
free-tier annotations, estimation_helpers), recomputes derived
monthly values, and protects $0 free-tier prices from overwrite.
- Delete 12 redundant pricing/<domain>.yaml files. They duplicated
oci-sku-catalog.yaml with worse abstractions and were nobody's
source of truth (no tool consumed them).
- Migrate the genuinely valuable knowledge from those 12 files
(billing models, BYOL rules, free-tier rules, ECPU vs OCPU,
X11M elastic model, hyperscaler comparisons, service nuances)
into kb/field-knowledge/pricing-knowledge.yaml — non-numeric,
no refresh needed.
- Result: pricing freshness check goes from 13 stale files to 0.
KB freshness automation:
- Add tools/kb_freshness.py — wrapper around kb_linter.check_freshness()
with --check, --auto-refresh, --json, --quiet modes. Bridges stale
files to their refresh tools (SKU catalog, compute domain, arch
center). Wired into the welcome flow as a pre-flight banner that
asks the user before refreshing.
- Fix pre-existing kb_linter bug: it crashed on the 45 multi-doc
YAML files (frontmatter + body pattern) because it used safe_load
instead of safe_load_all. Freshness check was effectively dead.
- Standardize timestamp field: linter now accepts last_verified,
last_updated, and last_refreshed; refresh_arch_catalog writes
last_verified instead of last_refreshed.
- Add make freshness / make freshness-refresh targets.
Skill alignment with Anthropic Agent Skills best practices:
- Rename `name: OCI Deal Accelerator` to `oci-deal-accelerator`
to comply with the [a-z0-9-]{1,64} spec.
- Refactor SKILL.md from 674 to 445 lines via progressive disclosure:
extract WA review output format, ECAL readiness format, and output
conventions into docs/skill/*.md referenced from the main file.
- Add scripts/sync-skill.py + make sync-skill: source of truth is
root SKILL.md, .agents/skills/oci-deal-accelerator/SKILL.md is
auto-generated. make lint validates sync.
- Add evaluations/ with 3 manual baseline scenarios (welcome-flow,
full-proposal, wa-review) per the Anthropic best-practices guidance
to "build evaluations first."
Welcome flow hardening:
- Tighten CLAUDE.md to MANDATE reading SKILL.md before showing the
menu (no improvising), and document the freshness pre-flight check
with the ask-before-refresh user flow.
- Update SKILL.md welcome flow to instruct: parse kb_freshness JSON,
show banner with stale count + oldest file, prompt user to refresh
(only when an automated tool exists), fall back silently on errors.
Linter hygiene (zero remaining issues):
- Expand config/kb-tags.yaml taxonomy with features, operations,
metrics, limitations sections covering 31 previously-unknown tags
used in field findings (rac, ecpu, refreshable-clone, hnsw, etc.).
- Assign owners for kb/compatibility/, kb/competitive/,
kb/well-architected/ (Diego Cabrera as default until team grows);
kb/pricing/ marked as "Auto-refreshed" since it no longer needs
human ownership.
- kb_linter accepts top-level `date` as fallback for contributor
block; migrate FF-202603-008 from legacy `reported_by` to
contributor block.
- Result: linter goes from 45 issues to 0.
Other:
- Recompute estimation_helpers monthly values in compute.yaml after
the price refresh (they were derived from the old E5/A1 numbers).
- Add kb/README.md — contributor guide (directory map, frontmatter
spec, refresh tooling, review cadence).
