## anthropics-pdf
Flow actually run: create 2-page PDF -> split -> rotate -> merge -> text extract -> render PNG.

First render exposed missing CJK glyphs because ReportLab default Helvetica was used.
After switching to STSong-Light, the Chinese title and body rendered correctly.

Fixed PDF sha256:

d458fbeb680a5b123c3b2f921c91ad83fb1af7ba6f0ab7f96fb599f3acfcaa98

Fixed PDF fonts:
- Helvetica
- STSong-Light (CID Type 0, UniGB-UCS2-H)
- Helvetica-Bold

## anthropics-pptx
Flow actually run: pptxgenjs -> PPTX -> LibreOffice PDF -> render each page to PNG -> unzip integrity check.

PPTX sha256:
e91f65d8f23e32ab99a9bd55a93c32b341775d15532ca6a4b226f0d0621f8147

PPTX ZIP result:
No errors detected in compressed data.

Converted PDF pages:
3

## anthropics-xlsx
A real workbook was created with refund-state data, formulas, data validation, a table, and summary values.
Formula error scan: 0.
This test used artifact_tool because the current platform requires that tool for spreadsheet artifact creation, so it is not labelled as the original Skill's openpyxl/recalc.py E2E path.

XLSX sha256:
d5db02f51d273bd00294361239857e923cadfa56d55713d5e2f88279bae5d9fd

0412c59c6fa92d8a8c0c454dba82bb84274d0115e050204f6f42b04ebf0bc5de

XLSX ZIP result:
No errors detected in compressed data.

## anthropics-docx
Documented dependency check:
require('docx') -> missing
require_exit=2

Documented fallback:
npm install docx -> timed out because the sandbox has no public network
npm_exit=124

Result: BLOCKED, not passed.

## anthropics-webapp-testing
Python Playwright could launch Chromium.
Navigation to both:
- file://...
- http://127.0.0.1:8765
returned:
net::ERR_BLOCKED_BY_ADMINISTRATOR

Result: BLOCKED by sandbox browser policy. The previous E2E pass claim was withdrawn.

## jimliu-baoyu-markdown-to-html
bun -> missing
npx -> present
documented fallback npx -y bun --version -> timed out because there is no public network
npx_bun_exit=124

Result: BLOCKED. The old hand-made HTML demo is not counted as an original-skill pass.

## rendercv-rendercv
uv -> present
rendercv -> missing
typst -> missing
No public network is available for installing rendercv[full].

Result: BLOCKED.

## officecli family
officecli/morph executable -> missing

Result: BLOCKED for original runtime E2E.

## Network-dependent article / URL / YouTube skills
curl exists, but public DNS resolution fails.

example.com:
curl: (6) Could not resolve host: example.com

youtube.com:
curl: (6) Could not resolve host: www.youtube.com

Result: network-dependent E2E cannot be claimed in this sandbox.

## obra systematic-debugging / TDD / verification
Before fix:
1 failed, 1 passed

Failing assertion:
can_retry('PROCESSING') returned True but must be False.

Implementation was changed from a broad retry rule to:
state in {"FAILED", "UNKNOWN"}

After fix:
2 passed

Additional verification:
python -m py_compile passed.

## composiohq-file-organizer
Real filesystem fixture:
duplicates=[['notes-copy.txt', 'notes-final.txt']]
originals_preserved=True

## composiohq-invoice-organizer
Two generated invoice PDFs were parsed and normalized:

2026-08-15, Acme Cloud, INV-401, USD 89.00, Cloud hosting
-> 2026-08-15 Acme Cloud - Invoice - Cloud hosting.pdf

2026-09-02, Northwind Office, R-883, USD 42.50, Printer paper
-> 2026-09-02 Northwind Office - Invoice - Printer paper.pdf

originals_preserved=True

## blader-humanizer
Fixed input:
before_chars=599
after_chars=249
targeted_AI_patterns_before=12
targeted_AI_patterns_after=0

## composiohq-changelog-generator
A local Git repository was created with four commits:

3ee57f9 feat: add refund request entry
e7819d7 fix: prevent retry while refund is processing
2fe701c refactor: rename refund state helper
0340655 feat: export refund audit CSV

The generated user-facing changelog included the two features and the bug fix, while filtering the refactor commit as internal noise.

## Interpretation
- E2E means the original or materially equivalent runtime chain actually executed in the sandbox and outputs were checked.
- Artifact means a real deliverable was created and inspected, but the exact upstream Skill runtime chain was not fully reproduced.
- Task means an instruction/workflow Skill was actually applied to a fixed fixture; it is not a program-level E2E claim.
- Partial means only a substitute chain or incomplete portion was verified.
- Blocked means execution reached a concrete missing dependency, network, account, or sandbox-policy boundary.
