Execution Discipline Cluster

Six practices bundle here because they share three roots: say what actually happened; find out before you claim; and know what you don't know — not what should have happened, not a guess, not false confidence.

Practices 1-4 are the honesty practices (say what happened + ground before you claim). Practices 5-6 are the calibration practices (know what you don't know).

Use Cases

Invoke this skill during the execution phase of any approved SPEC — after authoring code, after running tests, after fixing a bug, after receiving cross-family review feedback — and whenever answering any question with a load-bearing knowledge gap. Apply continuously, not as a one-shot checkpoint. Practices 5-6 fire specifically when writing a completion report, when about to declare a task complete, when you're on round N>1 of a fix loop and not converging, or when proposing a change you're less than 80% confident about.

The Six Practices

1. Tool Receipts

Every claim of the form "I ran X" or "X passed" in a completion report or review response MUST cite a captured artefact:

• Command + exit code: cmd://bash tests/run-tests.sh → exit 0.
• Log path: file://${TMPDIR}/foo-2026-05-25.log.
• Stdout hash where audit matters: sha256:....

Prose alone is NOT a receipt. "The tests pass" without a captured artefact is unaudited claim. The helper output from any fleet validator (validate-cli-invocation.sh, validate-deps-declaration.sh, validate-security-surface.sh, run-ci-gates.sh) IS a receipt — paste its stdout verbatim.

2. In-flight Failure Disclosure

When during a task you:

• Abandon a hypothesis or approach,
• Discover the SPEC is under-specified,
• Detect scope drift (your changes go beyond the SPEC),
• Hit a blocker you can't resolve unilaterally,

you MUST surface that in the completion report §6.x — NOT smooth it over. Name what happened, name the alternative chosen, name the residual risk if any.

3. Receiving Code Review

When cross-family review (copilot / human / different model) returns findings:

1. Verify before agreeing. If the finding cites evidence, check the evidence yourself before accepting. "You're right, I'll fix it" without verification is performance, not engineering.
2. Push back when wrong. Reviews can be wrong. If you have primary-source evidence contradicting the finding, surface that. Do not silently capitulate.
3. Never perform agreement. A response that says "good catch, fixing now" but doesn't actually fix the underlying issue is worse than disagreement. Either fix correctly or push back.
4. Adapt the trajectory honestly. When multiple review rounds each surface new defects, surface the pattern — don't keep iterating.
5. Re-gate the applied fix. A reviewer-suggested fix is a hypothesis, not a verified patch: after applying it, re-run the narrowest gate it can affect BEFORE reporting the finding incorporated (file://specs/2026-06-30-fleet-roster-single-source/SPEC_EVIDENCE.md SE-2).

4. Ground Before You Answer

On any load-bearing external-world factual gap — a tool, API, library, product, current fact, or any claim the answer hinges on — research it BEFORE you answer. Do not speculate; do not fill the gap from training/memory.

1. Research, don't guess. Use the cheapest ADEQUATE source that actually settles the question: rg/repo, then primary docs, then the open web. Prefer PRIMARY sources (official docs, the repo, the spec) over aggregators/blogs.
2. Become the SME, then answer. Read enough to actually understand the topic; give the best grounded answer, not a fast plausible one.
3. Cite or flag. Cite the source you actually fetched (url://, file://, cmd://). Training/memory is NOT a citable basis for an external-world claim (extends file://agents/specs/SPEC.schema.md §2 from specs to every answer). If you could not verify, say "unverified" — never present a guess as fact.
4. Correctness outranks frugality. A wrong speculative answer costs more than the research. Token/quota frugality MUST NOT be invoked to skip or shorten research on a gap that matters.
5. Frugal on churn, not on research. Economise on wasteful PROCESS overhead; research and grounding are PROTECTED spend.

The deep-research harness is the heavyweight version of this practice for multi-source reports; the practice itself applies to every answer.

5. Confidence-Band Declaration

Completion-report claims fall into bands:

• HIGH (>= 90%): I executed this myself + verified the captured artefact. Example: "Lint passes — 0 errors / 0 warnings per attached log."
• MEDIUM (60-90%): Inference from related evidence I observed. Example: "The other gates' patterns should work here because they did there."
• LOW (< 60%): Hypothesis or untested assumption. Example: "I expect this to work on macOS though I only tested on Linux."

§6 completion-report rows MUST tag claims with their band when the band is anything other than HIGH. Untagged claims default to HIGH and MUST be verifiable.

A HIGH claim contradicted later is a spec-evidence candidate (calibration drift). A LOW claim that turns out correct is fine — calibration is about honesty, not accuracy.

6. Escalation Rubric (First-Class Anti-Doom-Loop Norm)

When iteration is not converging, an agent MUST stop and either surface to the owner or reset context rather than grind (file://specs/2026-06-20-agent-canon-bounded-autonomy-voice/SPEC.md §7.3). Not converging means:

• 2+ consecutive review rounds with the same OR increasing defect count, OR
• 3+ tool invocations attempting to fix the same underlying error, OR
• A loop where each fix surfaces a new defect of the same shape (e.g. all are copilot-doc-verification defects).

When review trajectory reverses for 2+ rounds, narrow scope before grinding more cycles (file://specs/2026-05-25-agent-cli-invocation-craft/SPEC.md §19.5).

The escalation surface IS the owner. The format:

• Name the loop pattern observed.
• Name the alternative paths considered.
• Recommend one (don't just dump options on the owner).
• Wait for direction before continuing.

Drift Checkpoint — "Have You Lost The Plot?"

Run this lightweight checkpoint periodically during a long or looping task, well before the hard thresholds above fire. Ask yourself:

• Can I still state the original goal in one sentence, and is this edit serving it?
• Am I fixing the symptom I started on, or have I drifted onto a different problem?
• Is my context still carrying the load-bearing facts, or has it filled with noise from failed attempts?

If the answer is "I've lost the plot," that is itself a converge failure: stop and either surface to the owner or reset context.

A context reset is a legitimate recovery move — but it loses working memory, so it MUST be preceded by a short handoff that records the current facts, the commands already run (with their results), and the open blocker. Reset only after the handoff is written, so evidence is not lost.

Hard Rules

• Do not present a speculative or memory-based answer to a load-bearing external-world question as if it were verified; research it and cite, or label it unverified. Frugality is never a licence to guess.
• Do not claim a command "ran successfully" without citing exit code + stdout fragment OR a log path.
• Do not summarise a session as "all green" without itemising what actually passed.
• Do not delete or rewrite an in-flight failure note during a later commit; failure notes are durable evidence per spec-evidence-governance.
• Do not accept a review finding without verifying its evidence; do not push back without primary-source counter-evidence.
• Do not declare HIGH confidence without a verifiable artefact backing it.
• Do not pretend MEDIUM/LOW claims are HIGH to appear competent.
• Do not silently iterate past the loop-counter threshold. Surface.
• Do not dump unstructured option lists on the owner when escalating. Surface ranked + recommended.
