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

slope-retro 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 9d 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

SLOPE Post-Merge Retro

Use this after the PR is merged, or when the user asks to preserve lessons from a completed sprint or PR.

Prepare

  1. Confirm the sprint number from slope sprint status, the roadmap, the scorecard, or the user.
  2. Capture the merged PR number when available.
  3. Identify a short summary, durable learnings, hazards, and follow-ups. Do not include secrets or private tokens.

Run

  1. Preview when details are uncertain: slope retro post-merge --sprint=<N> --pr=<PR> --summary="<summary>" --learning="<learning>" --dry-run
  2. Persist the retro: slope retro post-merge --sprint=<N> --pr=<PR> --summary="<summary>" --learning="<learning>" --hazard="<hazard>" --follow-up="<follow-up>"
  3. Repeat --learning, --hazard, and --follow-up as needed.
  4. Use --learning=project:8:<text> or another supported category[:weight]:text prefix when the memory category matters. Supported categories are workflow, style, project, hazard, and other; process is accepted as an alias for workflow; weight must be 1-10.

Verify

  1. Check command output for the saved .slope/retros/post-merge/sprint-N[-pr-M].json path.
  2. Confirm memory persistence with slope memory search "<distinct learning text>".
  3. If the command reports skipped memories, treat them as duplicate-safe persistence unless the user expected a new learning.

Report

Tell the user the retro path, memory rows added/skipped, and any follow-up work captured. If a follow-up should become roadmap work, add or triage it before ending the phase.

Changes

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.
