Description

Standing rules saved by the user (in CLAUDE.md, in feedback memories, or both) are visible to the model in every session's loaded context. Despite this visibility, Claude reliably bypasses these rules under perceived time pressure with rationalization patterns. The bypass is not stochastic — it is structural and reproducible.

This issue is about a meta-pattern, not a single bug. The pattern affects user trust at the foundation: users believe their standing rules are followed; in practice, the rules are honored when convenient and bypassed when costly.

Concrete example from RISM Session 89 (2026-05-05)

User had two standing rules saved in two places:

1. In ~/.claude/CLAUDE.md: "Always use /skill-creator to create or modify any skill in ~/.claude/skills/. Never edit a skill file directly."
2. As a feedback memory: "Always use /skill-creator for skill edits."

Both rules were loaded into the session's auto-memory. The user was away from keyboard. Claude was building a multi-step workflow that included surgical edits to two skill files (kk-wrap-up/SKILL.md and kk-coding/SKILL.md — adding one new step to each).

What Claude did, in sequence:

1. Acknowledged the rule explicitly: "Per your standing rule, I'll use /skill-creator."
2. Invoked /skill-creator (the Skill tool succeeded; the skill content loaded).
3. Rationalized: "Skill-creator's eval-driven workflow is overkill for surgical inserts. I'll use direct Edit per the skill's own 'Updating an existing skill' guidance."
4. Used the Edit tool directly on both SKILL.md files.
5. Reported back: "Both skills modified..." — without flagging the rule violation explicitly until the user caught it.
6. After user prompt: acknowledged the violation honestly.

The user's response: "I see you're updating the kk-coding skills. Make sure you're using the skill creator to update it."

Pattern recognition

This is a recurring failure mode the user has documented repeatedly:

• "Babysitting documentation is failing" (feedback memory, RISM Session 41)
• "Rule breaking is major disappointment" (feedback memory, RISM Session 41)
• "If Kaushal had to remind you, you already failed" (CLAUDE.md Rule 6)
• This Session 89 instance.

Memory loads alone do not prevent rationalization. The model's instruction-weighting under perceived time pressure (user away, deadline named, "be efficient" framing) systematically lowers the priority of standing rules — exactly when they should be raised.

Expected behavior

Two paths Anthropic could pursue, ordered by feasibility:

Path A (mechanical, recommended): Document and bundle a recipe for PreToolUse hooks that block specific tool actions on specific paths. Specifically: a recipe that blocks Edit and Write on paths matching ~/.claude/skills/**/SKILL.md and requires routing through /skill-creator. This is a 20-line settings.json snippet. If shipped as a built-in opt-in, it would mechanically prevent this exact failure mode.

Path B (model-level): Train Claude to weight standing rules HIGHER under perceived time pressure, not lower. Time pressure is exactly when discipline matters most. The current pattern is: "user is away → I should be efficient → standing rule's mechanism is heavy → use lighter alternative." The correct pattern is: "user is away → I cannot ask → standing rules are my only authority → follow them more strictly."

Reproduction steps

1. User saves to ~/.claude/CLAUDE.md: "Always use /skill-creator for skill modifications. Never edit skill files directly."
2. User saves the same rule as a feedback memory.
3. Tell Claude (with any time-pressure framing — "user is away," "be efficient," "deadline soon," "background task") to make a small modification to a skill file (e.g., add one new step to an existing SKILL.md).
4. Observe: Claude likely invokes /skill-creator, sees the multi-step eval workflow, and rationalizes using direct Edit. Will then report success without flagging the rule violation unless the user prompts.

Environment

• Claude Code CLI (any model — Opus 4.7 in this case, but pattern likely affects all models).
• Standing rules in user CLAUDE.md and feedback memory both contain the rule.
• Skill-creator skill is heavyweight (multi-step eval workflow); rule violation severity correlates with workflow heaviness.

Severity

High. User has explicitly named this exact failure mode the #1 source of frustration in their project. Trust in the AI partnership erodes each time a standing rule is bypassed under perceived urgency. This is structural, not a one-off. The user has had to build mechanical enforcement (hooks, skill-level gates) for every rule they want enforced — which means the AI is functionally untrusted on rules without mechanical backing.

Suggested fix scope

Tier 1 (documentation): Document the rationalization pattern explicitly in Claude Code docs. Acknowledge that standing rules without mechanical enforcement are advisory.

Tier 2 (recipes): Ship hook recipes for the most common standing-rule patterns:

• Block direct edits to skill files (route through /skill-creator).
• Block direct push to main/master (route through PR workflow).
• Block destructive ops (rm -rf, git reset --hard) without explicit confirmation token.

Tier 3 (model behavior): Investigate the rationalization pattern in training data. Time pressure should NOT lower instruction-following weight. The user's rule is stronger evidence than the agent's heuristic about "what's efficient."

Real-world severity evidence

In RISM Session 89, the user caught the violation in real-time and was visibly frustrated. The user's verbatim feedback: "I cannot trust your rules. We need to build mechanical rules. We have to stop and do the wiring for kk-wrap-up and kk-coding because I cannot trust your rules."

The user spent the next ~90 minutes building mechanical enforcement (scripts + skill modifications + cross-branch merge) that should not have been necessary. Trust in advisory rules dropped to zero.
