What it does

PPTX Render Review is an agent skill from aiden0z/pptx-renderer. Use when reviewing PPTX renderer visual fidelity, triaging failed or needs-review oracle cases, inspecting PDF/PNG versus HTML screenshots, checking renderer bugfix side effects, planning regression coverage, or saving manual support verdicts in this repository.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Documents & Office, covering PowerPoint presentations. It works with Microsoft PowerPoint. The repository describes itself as: High-fidelity, browser-native PPTX renderer in TypeScript. Parses OOXML into HTML/SVG DOM with rich text, shapes, images, tables, 2D charts, SmartArt, equations, effects, and… The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit cf5b63d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • jq
    • pnpm
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, pnpm and curl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

PPTX Render Review loads about 1.5k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 522 words of instructions outside code blocks.

~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PPTX Render Review

Overview

Use renderer screenshots, diff images, and oracle metrics to make fast visual fidelity judgments. Start from side-by-side review, then use diff-first as a diagnostic lens; stay read-only unless the user asks for a fix.

Required Context

From the repository root:

bash
pwd
git status --short
find test/e2e/reports/oracle-failures -maxdepth 1 -type f -name '*.json' -print0 | xargs -0 ls -lt | head

For current quality, compare generated_at values and prefer the newest report matching the requested corpus.

Review Sources

Source order:

NeedSource
Interactive visual reviewhttp://127.0.0.1:5173/test/pages/e2e-compare.html
Single native slide/test/pages/render-slide.html?file=testdata/cases/{case}/source.pptx&slide=N
Metricstest/e2e/reports/oracle-failures/*live*.json or requested report
Diff and screenshotstest/e2e/reports/{case}_slide{N}_{pdf,html,diff}.png
Manual verdict storetest/e2e/reports/oracle-failures/manual-review.json
Support catalogtest/e2e/reports/oracle-failures/support-catalog.json

Workflow

  1. Confirm report freshness:
bash
jq '{generated_at,total_cases,
  passed:(.results|map(select(.passed==true))|length),
  failed:(.results|map(select(.passed==false))|length),
  needs_review:(.results|map(select(.needs_review==true))|length)}' test/e2e/reports/oracle-failures/<report>.json

If it is not the newest matching corpus, call it stale.

  1. Confirm dev servers only when browser/API review is needed:
bash
pnpm dev:e2e

If servers already run, reuse them.

  1. Pick a review set for the changed rendering area:
AreaPrefer samples
Shape geometrytarget shape id, related presets, adjustment variants
Fill/strokegradient, scheme color, alpha, connector, multi-path
Chartaxis, legend, marker, combo, stock, doughnut, data labels
Text/tablepypptx text, table alignment, composite cases
SmartArtlayout family, generated PNG ground truth, edge-heavy
  1. For renderer fixes, build a small interaction matrix before changing code or declaring the fix complete. Include the user-visible positive case, the inverse/opt-out case, and the parent container or browser behavior that could expose a side effect. For text layout changes, inspect a:bodyPr and cover relevant combinations of wrap, horzOverflow, vertOverflow, spAutoFit, normAutofit, noAutofit, insets, vertical text, bullets, multi-paragraph text, and adjacent runs. A leaf TextRenderer test is insufficient when the visible behavior depends on the ShapeRenderer text container.

  2. Prioritize:

PriorityMeaning
P0large diff in changed rendering area
P1passed=false or semantic mismatch
P2passed=true, needs_review=true
P3representative supported sample for baseline
  1. Inspect selected cases in side-by-side view first. Use diff-first to locate suspicious regions, then confirm in ground-truth/rendered side-by-side before making a verdict. Prefer PNG ground truth; use PDF only when PNG is unavailable or requested.

Default to decision metrics first: auto gate (PASS, REVIEW, FAIL), SSIM, color correlation, and needs_review. Open Diagnostics only when locating a mismatch or explaining why a case needs review; diagnostic metrics include foreground IoU, chamfer, MAE, text coverage, word counts, and shape count.

  1. Save verdicts only after per-slide visual inspection:
bash
curl -sS -X POST http://127.0.0.1:8080/api/manual-review \
  -H 'Content-Type: application/json' \
  -d '{"test_file":"CASE","slide_idx":0,"verdict":"supported","note":"short reason"}'

Use supported, unsupported, or unsure. Notes name visible mismatch, not guessed code cause.

Red Flags

  • Bulk-marking from metrics alone.
  • Treating diagnostic metrics as top-level verdict gates.
  • needs_review=true without expanding from diff into side-by-side inspection.
  • Old generated_at or wrong corpus/source.
  • Notes guess code cause instead of visible mismatch.
  • Text/layout fixes tested only at the run/span layer without the shape text container.
  • Missing inverse coverage for explicit opt-outs such as horzOverflow="overflow".

Reporting Back

Report the report path, generated_at, selected review set, auto gate summary, diff observations, saved verdicts, and stale/missing data. Keep diagnostic metrics secondary unless they explain a visible issue.

Common Mistakes

  • Do not use windows-all-eval.json or all-shapes-eval.json blindly.
  • Do not mark a case supported from metrics alone when needs_review=true.
  • Do not bulk-save manual verdicts; save only case/slide verdicts you inspected.
  • Do not chase fg_iou as a pass/fail gate; it is diagnostic only.
  • Do not modify renderer code during review unless the user asks for a fix.
