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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00086 | $0.00859 |
| Opus 5 | $0.00043 | $0.00430 |
| Sonnet 5 | $0.00017 | $0.00172 |
| Haiku 4.5 | $0.00009 | $0.00086 |
Grade A, and why
change-classification 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 6d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Change Classification
Domain skill for analyzing and classifying code changes before committing.
Iron Law
CLASSIFY BEFORE COMMITTING. Every changed file gets a classification. Unclassified files do not get staged.
Committing without classification is how out-of-context changes, secrets, and unintended modifications reach the repository.
Classification Algorithm
For each changed file, evaluate signals to classify as: in-context, uncertain, or out-of-context.
Primary Signals (Strong)
| Signal | Classification | Detection |
|---|---|---|
| File already in branch diff | in-context | git diff --name-only $DEFAULT_BRANCH...HEAD includes file |
| File matches issue keywords | in-context | File path contains words from issue title/body |
| File in active task | in-context | File path matches TaskList task descriptions |
| File matches task directory | in-context | Same top-level directory as task-related files |
Secondary Signals (Supporting)
| Signal | Classification | Detection |
|---|---|---|
| Same directory as other changes | lean in-context | Sibling of already-classified in-context file |
| Test file for changed module | lean in-context | Naming convention match (e.g., foo.rb → foo_test.rb) |
| Config in project root | uncertain | Changes to dotfiles, config, package manifests |
| Unrelated directory | out-of-context | No connection to issue or tasks |
Red Flags
These always get flagged regardless of context:
| Pattern | Action |
|---|---|
.env*, credentials*, *secret* |
Block — never commit |
*.lock, package-lock.json |
Warn — verify intentional |
| Large binary files (>1MB) | Warn — verify intentional |
| Auto-generated files | Note — may need regeneration |
First-Touch Detection
A file is "first touch" when:
- 0 commits on the current branch modify it (
git log $DEFAULT_BRANCH..HEAD -- fileis empty) - Large additions (>50 lines added)
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.

change-classification is a skill published in the GitHub repository synaptiai/synapti-marketplace (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 86 tokens to every session and 859 once invoked, about $0.0004 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 2026-09-03.
Other skills, from other repositories
document
Run /document pr | changelog | release-note | postmortem (or let it ask) to write the human facing prose about a change. Drafts from the real commits and diff, writing to the right place. Does not write code, tests, or specs.
create-pr
Creates a GitHub Pull Request on the current branch with a description focused on WHAT changed (not HOW). Uses emojis in the title and description. Use when the user asks to create a PR, open a pull request, or submit changes for review. Triggers on mentions of PR, pull request, merge request, or code review.
loop-close
Closes a slice or a session - adversarial audit of the diff, ledger entry, selective commit, honest report, and the handoff for the next session. Use before considering anything finished.
Implement
Implement one micro spec — one commit, one PR. The micro spec is the complete instruction set; write only the files in its File Operations table, verify against its acceptance criteria, commit.
strict-tdd
Strict RED->GREEN->REFACTOR test-driven development with enforcement. Never write production code before a failing test. Atomic commits per TDD cycle.
branch-and-worktree-workflow
Isolates feature work in its own branch or worktree and integrates it cleanly when done. Use this when starting work that should not disturb the current workspace, when several efforts must proceed in parallel on one repository, or when implementation is finished and the change needs merging, rebasing, or splitting…
