Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.00926 |
| Opus 5 | $0.00018 | $0.00463 |
| Sonnet 5 | $0.00007 | $0.00185 |
| Haiku 4.5 | $0.00004 | $0.00093 |
Grade A, and why
github-issue-dedupe 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 today.
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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub issue dedupe
Contract
| Field | Bound contract |
|---|---|
| Trigger | Find duplicates or check for similar issues against a target GitHub issue. |
| Authority | Remote: posts at most one comment on the target issue listing duplicates; requires explicit human invocation. Preview the issue and the comment consequence before posting. No credentials, data-at-rest changes, paid actions, publishing, deployment, remote bulk mutation, or irreversible deletion beyond that comment. |
| Side effect | Optionally posts one comment on the target issue listing the duplicates, only when the human confirms. Duplicate issues themselves are never modified, closed, labeled, or deleted. |
| Done | A duplicates classification is returned: a high-confidence duplicates list, or a no-duplicates classification for negative results. |
Inputs
- Target issue reference (owner/repo#number or URL). Required.
- GitHub repository scope to search (owner/repo). Required; defaults to the target issue's repository.
- Search terms, symptom phrases, error messages, or stack traces extracted from the target issue. Required; derived from the target issue title and body when not supplied.
- Optional: additional keyword overrides, labels to filter.
Procedure
- Resolve the target issue: read its title, body, labels, and comments with
gh issue view. Extract symptom phrases, error messages, stack traces, and distinctive keywords. Done when: the target issue is resolved and its search terms are extracted. - Bound the search scope to the named repository. Do not search outside it unless the human explicitly supplies a broader scope. Done when: the search scope is bounded to the named repository.
- Run a multi-strategy search over open and recently closed issues using
gh search issuesandgh issue list:- Keyword and title-similarity search from the extracted terms.
- Error-message and stack-trace overlap search.
- Symptom-phrase overlap search using multiple phrasings of the reported problem. Done when: all three search strategies have been run or recorded as non-runnable.
- For each candidate, compare it against the target issue across these dimensions: title similarity, shared error text, overlapping symptom descriptions, and matching reproduction steps. Discard the target issue itself. Done when: every candidate is compared across all four dimensions.
- Classify each remaining candidate as a duplicate or not. A candidate is a high-confidence duplicate only when 2 or more dimensions match the target issue. Done when: every candidate has a duplicate classification with the matching dimensions named.
- If no candidate has 2 or more matching dimensions, return a no-duplicates classification. Do not post a comment. Done when: the no-duplicates classification is returned.
- If one or more candidates qualify, present the duplicates list to the human with the target issue reference, each duplicate's number and title, and the matching dimensions. Done when: the duplicates list is presented to the human.
- Only when the human confirms, post one comment on the target issue listing the high-confidence duplicates. Do not modify, close, label, or delete any duplicate issue. Done when: the comment is posted or the human declines.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

github-issue-dedupe is a skill published in the GitHub repository OutlineDriven/odin-claude-plugin (35 stars, last pushed today), licensed Apache-2.0. It adds 36 tokens to every session and 926 once invoked, about $0.0002 per session on Opus 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 2026-09-06.
