SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00908 |
| Opus 5.5 | $0.00011 | $0.00363 |
| Sonnet 5.5 | $0.00005 | $0.00182 |
| Haiku 4.5 | $0.00003 | $0.00091 |
Grade A, and why
dedupe-issue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Detect duplicate issues
Compare a newly filed GitHub issue against candidate issues provided by the workflow and identify likely duplicates by similarity of title and description.
Inputs
Expect the prompt to include:
- the incoming issue's number, title, and description
- candidate issues prepared by the outer workflow
- the repository owner/name as context
Duplicate detection procedure
- Use the candidate issues prepared by the outer workflow as the comparison set.
- If no candidate issues are available, report that duplicate checking could not be verified in
summaryorissue_body, leaveduplicate_ofempty, and continue triage from the available local inputs. - Normalize the incoming issue's title and description by lowercasing, stripping leading/trailing whitespace, and collapsing runs of whitespace into single spaces.
- For each candidate issue in the comparison set:
a. Compute title similarity: compare the incoming title to the candidate title. Consider them title-similar when they share the same core noun phrases or intent after stripping common prefixes like "bug:", "feature:", "[request]", emoji, and markdown formatting.
b. Compute description similarity: compare the key symptoms, error messages, reproduction steps, and requested behavior between the incoming and candidate descriptions. Ignore boilerplate template sections (e.g., "## Environment", "## Steps to Reproduce" headers with empty content) that do not carry diagnostic signal.
c. A candidate is a likely duplicate when both of the following hold:
- The titles convey the same problem, feature request, or question (not merely sharing a common keyword).
- The descriptions overlap on at least one substantive detail: a shared error message, the same failing behavior, the same requested capability, or an equivalent reproduction scenario.
- Rank candidates by overall similarity (title weight ≈ 40%, description weight ≈ 60%) and select the top matches.
- Only flag an issue as a duplicate when 2 or more existing issues are identified as likely duplicates. A single weak match is not sufficient — the evidence must be corroborated across multiple existing issues to reduce false positives.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dedupe-issue is a skill published in the GitHub repository Terry-Mao/AICodingFlow (169 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 908 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
