What is rpce-maintainer-guidance?

A set of evidence-based guidelines for maintaining RepoPrompt CE, including how to investigate issues, plan changes, review compatibility, and handle migrations or performance concerns. It is guidance for decisions, not an implementation of those features.

Use it to scope fixes, distinguish confirmed facts from hypotheses, choose between an investigation and a code change, and check behavior during migration, restart, cancellation, or partial success.

It helps maintainers make smaller, safer changes based on the actual execution path, user impact, and project evidence.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.01418
Opus 5.5	$0.00035	$0.00567
Sonnet 5.5	$0.00017	$0.00284
Haiku 4.5	$0.00009	$0.00142

Security

Grade A, and why

rpce-maintainer-guidance 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 2mo 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.

RepoPrompt CE Maintainer Guidance

Use this skill as a project decision guide, not as an imitation of a person. Do not attribute inferred opinions to any individual. State uncertainty, cite the relevant principle, and let current repository instructions, source code, tests, product behavior, and explicit maintainer decisions override historical guidance.

Read references/guidance-sources.md when the task needs the evidence behind a principle, involves a disputed tradeoff, or changes model defaults, telemetry, Agent Mode, MCP, worktrees, persistence, or release behavior.

Decision workflow

Define the observable user impact and the invariant that should hold.
Trace the real execution path and source of truth before proposing a fix.
Separate confirmed facts, plausible mechanisms, unproven hypotheses, and unknowns.
Split mixed failure modes into independently testable issues or PR tracks.
Choose the smallest coherent change that fixes the cause without creating a parallel authority or speculative compatibility layer.
Check user-state, migration, crash, restart, cancellation, and partial-success behavior before declaring the design safe.
Check scale and concurrency: project-size growth, CPU contention, off-main-actor synchronization, caching, coalescing, and accidental whole-root work.
Keep asynchronous work observable. If users or agents cannot tell what is running, add an appropriate status or tool-card surface.
Validate at the affected boundary with the smallest useful test, then exercise the real UI or live MCP path when behavior depends on integration.
Recommend one of: implement now, investigate first, file or update an issue, stage as a follow-up, or decline as unnecessary.

Core principles

Fix causes, not symptoms

Ask why the unexpected state, stall, timeout, or invalid value exists.
Reject patches that merely mask a stall, retry around unexplained state, or replace data with blanks.
Treat extra fallbacks as complexity that must earn its place with a demonstrated failure mode.
Prefer an investigation when the causal chain is not yet supported by evidence.

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.
