Information routing decision matrix for Hermes Cortex agents. Defines when to consult live context vs session history vs memory vs docs, with explicit priority ordering, staleness handling, confidence scoring, and cross-reference chaining patterns for multi-source state resolution.
State Orchestrator — Information Routing Decision Matrix v1.0.0
When you need to resolve a question about system state, behaviour, or history,
where do you look, and in what order? This skill provides a decision matrix
that maps each information source to its appropriate use case, with priority
ordering, staleness handling, confidence scoring, and cross-reference chaining
patterns for resolving conflicts or filling gaps.
There are four distinct information sources available to a Hermes Cortex agent.
Each has a different purpose, trust profile, and freshness guarantee.
Source
Symbol
Definition
Best For
Limitations
Live Context
[LC]
Current tool outputs, file reads, command results, and any state observable via direct inspection in this session
Ground truth — what the system actually looks like right now
Ephemeral; lost when session ends
Session History
[SH]
Prior messages, tool calls, and outputs within the current conversation turn / session
Continuity — what was just said or done moments ago
Noisy; contains intermediate exploration; not curated
Memory
[M]
Persistent files (MEMORY.md, USER.md, checkpoints, recovery files) stored across sessions
Long-term recall — decisions, blockers, user preferences, past completions
Can go stale; requires manual checkpoint discipline
Docs
[D]
Static reference: SKILL.md files, official docs, READMEs, man pages, API specs, third-party sites
Understanding — what a tool, library, or protocol can do
Describes intent/design, not actual state
2. Priority Order
When answering a question or making a decision, consult sources in this order.
Higher priority always wins unless there is evidence of staleness or unreliability
(see §4 Staleness Handling).
Live Context ──── Highest Priority
│
Session History ──── Immediate Past
│
Memory ──── Persistent Knowledge
│
Docs ──── Reference (lowest priority for state questions)
2.1 Priority Rule
The closer the source is to the current observable system, the higher its
priority. Live context tells you what is. Session history tells you what
just happened. Memory tells you what was decided. Docs tell you what was
designed.
2.2 When to Defer to a Lower-Priority Source
Even though priority is hierarchical, there are cases where you should skip or
not fully trust a higher-priority source:
Live context is missing — the file doesn't exist, the command errored,
the tool returned nothing. Defer to session history or memory.
Live context is noisy — a command produced 10,000 lines of output and you
only need the configuration intent. The [M] checkpoint may be more useful.
Session history contradicts live context — the user said "I just changed
X" but live context shows X is unchanged. Live context wins.
Memory is stale — the checkpoint says "using port 8080" but lsof shows
port 8080 is free and 9090 is in use. Live context wins.
Docs describe a default that memory overrode — the write_file doc says
it auto-creates directories, but memory notes a custom wrapper that disabled
this. Memory wins over docs for custom behaviour.
All sources conflict — use the conflict resolution procedure (§7).
3. Decision Matrix
This matrix tells you which source (or combination) to use for common situations.
The Primary column is where you should look first. The Fallback column
is where to go if the primary is insufficient, stale, or contradictory.
Situation
Primary
Fallback
Rationale
"What does this file contain right now?"
[LC] read_file
[SH] last tool output if file was read earlier this turn
Files change; always verify live
"What did we just do?"
[SH] last 2-3 exchanges
[M] latest checkpoint
Session history is immediate; checkpoints are summarised
"Why did we choose this approach?"
[M] checkpoint or MEMORY.md
[SH] discussion leading to decision
Memory curates the rationale; session history is raw
"How does this tool/library work?"
[D] SKILL.md or official docs
[LC] try --help flag
Docs describe intended behaviour; live flags confirm presence
"Is this dependency installed?"
[LC] which/where/import check
[M] install notes
The only way to know is to check the actual system
"What has been done so far today?"
[M] progress list or checkpoint
[SH] full session log
Memory is curated; session history is thorough but verbose
"What are the user's preferences?"
[M] USER.md
[D] Hermes docs (defaults)
User preferences override defaults
"Did we already try this approach?"
[M] memory of recent attempts
[SH] tool call history
Memory is summarised; session history has the raw errors
"Is there a security concern here?"
[D] SECURITY.md, docs
[M] any prior security notes
Security policy lives in docs; past incidents live in memory
"What version of X is running?"
[LC] version command
[M] install log
Live check trumps any recorded value
"How did our last session end?"
[M] SESSION_RECOVERY.md or checkpoint
[SH] (not available across sessions)
Recovery files are designed for this
"Is the system healthy?"
[LC] health check command
[M] baseline health metrics
Compare live output to known-good baseline
"What is the project structure?"
[LC] ls or search_files
[D] README.md
Actual filesystem is ground truth; README may be out of date
"What did the user really mean?"
[SH] user's exact words
[M] user's known concerns/goals
User's latest message is primary; memory provides context
"Should I trust this memory entry?"
[LC] verify key claims live
[M] the entry itself
Verify before acting on potentially stale memory
4. Staleness Handling
A source is stale when its content no longer reflects the current system state.
Stale data can lead to incorrect decisions, repeated work, or confidence in wrong
assumptions.
4.1 Staleness Tiers by Source
Source
Typical Half-Life
Staleness Indicators
Check Before Use?
Live Context
Seconds — real-time
Tool error, empty output
No — it's live by definition
Session History
Minutes — within the turn
A later tool call contradicted it
No — but cross-check with LC if in doubt
Memory (checkpoint)
Hours — one working session
Timestamp older than last git commit, last file write
Yes — verify key assertions with LC
Memory (USER.md)
Days to weeks
User behaviour contradicts preferences
Yes — re-confirm with user if it feels off
Memory (MEMORY.md)
Days
Timestamp suggests pre-session
Yes — always verify claims about file state with LC
Docs (SKILL.md)
Weeks to months (versioned)
Version mismatch; file references changed
No — but cross-reference with LC for system-specific details
Docs (third-party)
Months to years
Deprecation notices, version drift
No — but be aware of potential drift
4.2 Staleness Resolution Procedure
When a source is identified as potentially stale:
1. IDENTIFY ──── Which source has the claim? What is its timestamp or version?
│
2. ASSESS ──── How old is it relative to the last known state change?
┌──────────────────┴──────────────────┐
▼ ▼
Likely fresh (>90% confidence) Likely stale (<50% confidence)
───────────────────────────── ─────────────────────────────
Use the source directly. Proceed to step 3.
│
3. VERIFY ──── Use [LC] to check the key claim. E.g.:
• If memory says "port 8080" → run `lsof -i :8080`
• If memory says "Python 3.11" → run `python3 --version`
• If memory says "file X has config Y" → run read_file on X
│
┌────────────┴────────────┐
▼ ▼
Confirmed Contradicted
────────── ────────────
Confidence Update memory with new value
restored. Use the live value going forward.
Proceed. Log the update.
4.3 Freshness Notation
Use these qualifiers when citing a source:
Label
Meaning
[LC]
Current turn, just fetched
[SH: -N]
Session history, N exchanges ago
[M: YYYY-MM-DD]
Memory entry from a specific date
[D: vX.Y]
Docs at a specific version
[LC verified M]
Memory claim confirmed by live check
[LC overrode M]
Live context contradicted memory; live wins
5. Confidence Scoring
Every piece of information routed from a source carries an implicit confidence
score that you should use when weighing competing claims.
5.1 Base Confidence by Source
Source
Base Confidence
Reasoning
Live Context
95%
Direct observation of current state. 5% deduction for tool limitations (e.g., read_file might truncate)
Session History
85%
Direct observation, but may be superseded by later LC. Reduce to 70% if >10 exchanges ago
Memory (checkpoint just written)
90%
Just saved, still fresh. 10% deduction for human error in checkpoint content
Memory (MEMORY.md)
75%
Curated but may be hours/days old. Deduction increases with age
Memory (USER.md)
80%
User-defined preferences, relatively stable
Docs (SKILL.md)
85%
Versioned, maintained, but describes intent not state
Docs (third-party)
70%
May describe different version or environment
5.2 Confidence Adjustments
Apply these adjustments to base confidence:
Condition
Adjustment
Source was just verified by [LC]
+10% (capped at 99%)
Source contradicts another source
-15% per conflicting source
Source is >24h old (memory)
-10%
Source is >7d old (memory)
-25%
Source has version mismatch (docs)
-20%
Source was written by the current session
+5%
Source is a third-party doc with known deprecations
-15%
Source is a recovery file from an interrupted session
-10% (may be incomplete)
5.3 Thresholds
Score Range
Action
≥ 90%
Act on the information directly.
70–89%
Use the information but cross-reference if it will lead to a destructive action.
50–69%
Do not act without live verification. Flag as uncertain.
< 50%
Discard the source or ask the user. Do not use for decision-making.
5.4 Multi-Source Consensus
When multiple sources agree, confidence is boosted:
2 sources agree: base + 5%
3 sources agree: base + 10%
4 sources agree: base + 15%
Any source -20% per dissenting source
strongly dissents:
6. Cross-Reference Chaining
Cross-reference chaining is the practice of following a link from one source to
another to resolve a question or fill a gap. This is especially valuable when a
primary source is insufficient.
6.1 Standard Chain Patterns
6.1.1 Gap Fill Chain
──────────────
[D: SKILL.md] mentions a technique
→ but the technique requires a specific tool version
→ [LC: tool --version] to check version
→ if missing, [M: install notes] for how to upgrade
6.1.2 State Verification Chain
─────────────────────────
[M: checkpoint] says "port 8080 is configured"
→ [LC: lsof -i :8080] to verify
→ if not found, [SH: last session] for discussion about port change
→ if not in SH, [M: MEMORY.md] for any port migration notes
6.1.3 Decision Recovery Chain
────────────────────────
Why was X chosen?
→ [M: decision log in checkpoint]
→ if ambiguous, [SH: conversation excerpts around decision time]
→ if still unclear, [D: comparative analysis of alternatives]
→ final resort: ask the user
6.1.4 Bug Diagnosis Chain
────────────────────
Something broke.
→ [LC: error output or traceback]
→ [M: what changed recently?] (checkpoint diff, git log)
→ [D: error documentation]
→ [SH: what was the last thing that worked?]
→ [LC: reproduce with minimal test case]
6.1.5 Preference Resolution Chain
────────────────────────────
How should I format output?
→ [M: USER.md] for explicit preferences
→ if not present, [D: Hermes docs defaults]
→ if platform-specific, [LC: check platform from env]
→ if still uncertain, [SH: user's past messages for stylistic hints]
6.2 Chain Termination Rules
A cross-reference chain terminates when:
Live context confirms the answer — you have direct evidence of current state.
The user provides a definitive answer — the agent asks and the user responds.
A confidence threshold is crossed — you have ≥ 90% confidence from multi-source agreement.
All sources are exhausted — no more sources to consult; report a blocker.
6.3 Chain Recording
When you execute a cross-reference chain, record it in memory for future sessions:
## Cross-Reference Chain — YYYY-MM-DD HH:MM UTC### Question
Why is the API returning 503 errors?
### Chain1. [LC] `curl -I https://api.example.com/health` → 503
2. [M] Checkpoint from yesterday: "Deployed new auth middleware at 14:00"
3. [SH] Prior discussion: "The new middleware requires a Redis connection"
4. [LC] `redis-cli ping` → Could not connect
5. [D] Internal docs: "Auth middleware v2 requires Redis 6.x"
6. [LC] `redis-server --version` → Redis 5.0 (too old)
### Resolution
Upgrade Redis to 6.x. Confidence: 95% (LC + D + M all agree).
6.4 Chain Length Guidelines
Chain Depth
Use Case
When to Stop
1–2 hops
Simple fact check, version query
After LC confirms or contradicts
3–4 hops
Debugging a known issue, restoring context
After root cause identified
5+ hops
Complex multi-source investigation
After chain converges (≥90% confidence) or all sources exhausted
7. Conflict Resolution
When two or more sources disagree, use this procedure.
7.1 Conflict Detection
A conflict exists when:
[LC] contradicts [M] on a factual claim (e.g., file content, version, port).
[M] and [SH] disagree on what was decided.
[D] describes behaviour that [LC] disproves.
Multiple [M] entries from different times give conflicting accounts.
7.2 Resolution Rules
Conflict
Resolver
Rationale
[LC] vs [M]
LC always wins
Live state is ground truth; memory may be stale
[LC] vs [D]
LC wins for state questions; D wins for behaviour/design questions
LC tells you what is; D tells you what should be — different questions
[SH] vs [M]
M wins if checkpoint was written after the SH event; SH wins if the event hasn't been checkpointed yet
A newer snapshot overrides a raw event; raw events override older snapshots
[M] vs [M] (different dates)
Newer wins — check timestamps
Explicit versioning of memory
[M] vs [D]
M wins for custom/local decisions; D wins for default/standard behaviour
Local overrides take precedence over defaults
[SH] entry contradicts itself
Discard the earlier part; keep the later
Latest statement in a session is the most current intent
User says X, [M] says Y
User wins — always
User is the ultimate authority on their own intent
7.3 Conflict Logging
After resolving a conflict, log it:
## State Conflict — YYYY-MM-DD HH:MM UTC### Conflicting Claims- [M: 2025-06-07] "API key is stored in ~/.secrets/api-key"
- [LC] read_file("~/.secrets/api-key") → File not found
### Resolution
LC overrode M. API key has been moved or deleted since the memory entry.
→ Checked [M: install notes] — no migration record found.
→ Checked [D: docs] — default location is ~/.config/app/api-key
→ [LC] read_file("~/.config/app/api-key") → "sk-<key-found>"
### Action Taken
Updated [M: MEMORY.md] with new path. Confidence: 97%.
8. Anti-Patterns
❌ Asking docs for state — don't read the SKILL.md to find out if something
is running. Check live context.
❌ Ignoring session history when it's relevant — if you just ran a command
3 exchanges ago, don't re-run it. Use session history.
❌ Over-chaining — don't follow a cross-reference chain beyond 5 hops
without asking yourself whether a direct LC check would be faster.
❌ False consensus — don't treat [M] + [D] (2 sources) as strong
consensus if both ultimately derive from the same source (e.g., both were
written from the same meeting notes).
❌ Confidence inflation — don't add the multi-source bonus if all sources
ultimately trace to the same original observation.
❌ Never checking memory — some agents operate entirely in live-context
mode and lose all continuity across sessions. Use memory for persistence.
❌ Ignoring staleness in docs — third-party tutorials and even first-party
docs can describe APIs that were deprecated. Cross-reference version numbers
with live context.
