Token cost

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.

Security

Grade A, and why

implement-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 3d 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.

What it actually says

Implement Issue

Implement changes for a GitHub issue.

Process

1. Load Context

Determine the issue number from the user's request, which may carry context beyond the number. Fetch the issue and any plan comments:

gh issue view <issue-number> --comments

Also check .claude/workspace/ for any plan files related to this issue. If no plan exists for a complex issue, suggest running /praxis:plan-issue first.

2. Setup Branch

Check existing local and remote branches for one related to this issue -- it may be named by issue number (feature/issue-123) or by description (feature/audit-improvements). If one exists, check it out. If not, create a new branch. For sub-issues of a larger feature, branch from the parent feature branch rather than main.

3. Read Relevant Docs

Based on the issue area, read the appropriate project documentation in docs/.

4. Implement

Follow the plan if one exists. Work through changes methodically. Make progressive commits as logical units of work are completed rather than one monolithic commit at the end.

5. Update Documentation

Changed behavior may need doc updates. Commit doc changes.

6. Verify

Run the Verify commands from CLAUDE.md. Fix any failures and commit the fixes before pushing.

7. Push

Push the branch with all commits.

8. Post Summary

gh issue comment <issue-number> --body "## Implementation Complete

Branch: \`<branch-name>\`

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.
