1 scripts

HTML-rendered version of /cc-canary — produces a long-form nerf-detection report as a standalone dark-theme HTML file and auto-opens it in the browser. Same analysis as /cc-canary (forensic markdown writeup), same narrative placeholders, but the output is a styled HTML page suitable for viewing, sharing, or printing. Writes `./cc-canary-<YYYY-MM-DD>.html` to the current directory.

cc-canary-html — HTML nerf-detection report

Same analysis as
/cc-canary
, rendered as HTML.

Bundled script

scripts/compute_stats.py

does the work in ~2.5s: scans JSONLs, runs inflection + transition-day detection, builds pre/post aggregates, cross-version comparison, hour-of-day, word frequency, three-period thinking depth, visibility transition, per-turn rates, and abnormalities — then renders a complete HTML skeleton with every table filled and ASCII bar charts preserved in monospace

<pre>

blocks. Narrative slots are marked

<!-- C: ... -->

.

Default window:

60d

. Accept

7d / 14d / 30d / 60d / 90d / 180d

.

Your 4-step job

1. Run the script

Bash(python3 <SKILL_DIR>/scripts/compute_stats.py --window {window} --render-html /tmp/cc-canary-skeleton-{window}.html > /dev/null 2>&1)

<SKILL_DIR>

:

.claude/skills/cc-canary-html/

→ fallback to

~/.claude/skills/cc-canary-html/

.

Flags:

--window {Nd}

(required);

--include-agents

;

--min-user-words N

.

If the script fails: report error, retry once with

--include-agents

, else stop. Never fall back to hand-computation.

2. Read the HTML skeleton

Read /tmp/cc-canary-skeleton-{window}.html

3. Fill every

<!-- C: ... -->

placeholder and save

Replace each placeholder comment with HTML-safe narrative text. Escape

,

in anything you write. Keep all tables,

<pre>

bar charts, and existing HTML untouched. Save as:

Write ./cc-canary-{YYYY-MM-DD}.html

4. Open in the browser

Detect platform via

Bash(uname)

:

Darwin

→

Bash(open ./cc-canary-{YYYY-MM-DD}.html)

Linux

→

Bash(xdg-open ./cc-canary-{YYYY-MM-DD}.html)

anything else →

Bash(start ./cc-canary-{YYYY-MM-DD}.html)

If the open command fails, just print the absolute path — don't error.

End your message with:

Wrote /Users/.../cc-canary-{date}.html — opened in browser.

(or

… open manually.

if open failed).

Narrative placeholders

Same set as

/cc-canary

:

```
verdict-line
```
— HOLDING / SUSPECTED REGRESSION / CONFIRMED REGRESSION / INCONCLUSIVE + brief justification
```
summary
```
— 1–2 sentences, terse: what moved and by how much
```
timeline
```
— 1–2 paragraphs
```
xv-para
```
— 1 paragraph on cross-version (if §2 is present)
```
finding-N-class
```
× up to 5 — inline classification: model-side | user-side | ambiguous
```
finding-N-reason
```
× up to 5 — 2–3 sentences max, evidence-first
```
root-cause
```
— 3–5 paragraphs
```
what-would-help
```
— 2–4 concrete bullets
```
appendix-a1…a4, b, c, d, e, f, g, h
```
— 1 paragraph each
```
meta-note
```
— 2–5 sentences, first person, honest

Verdict calibration

HOLDING: ≤1 model-side signal
SUSPECTED REGRESSION: 2–3 model-side signals
CONFIRMED REGRESSION: ≥3 model-side signals + non-empty cross-version showing decline +
```
session_count ≥ 15
```
+ ≥2 models +
```
inflection.gap_sigma ≥ 1.0
```

INCONCLUSIVE:

session_count < 15

OR

inflection.method == "fallback_split_half"

with overlapping confounds

Cap at SUSPECTED when: only one model; <15 sessions; single-project with project starting mid-window; inflection coincides with a visible user-side event.

Hard rules

Never read, grep, or glob
```
~/.claude/projects/**/*.jsonl
```
. Never run
```
jq
```
/
```
awk
```
/
```
wc
```
on session files. Script owns all that.
Never touch existing HTML, tables, or
```
<pre>
```
blocks — they came from real data.
HTML-escape any narrative text you insert (
```
<
```
,
```
>
```
,
```
&
```
→ entities).
Every finding gets a classification label.
Hedge when cross-version is empty or
```
session_count < 15
```
.
Do not verdict CONFIRMED REGRESSION without the full checklist.
Do not save the skeleton as-is — replace every
```

```
first.

Failure modes

Script import error → check
```
python3 -V
```
≥ 3.8; retry once with
```
--include-agents
```
; else stop.
Skeleton < 5KB → likely no sessions in window.

inflection.method == fallback_split_half

→ state it; cap at SUSPECTED.

Cross-version Δ
```
None
```
→ div-by-zero when model-A value is 0; note the confound.
Browser-open command fails → don't error; print the path and move on.
